Cyclists Riding on Sidewalks In London Ontario

Cycling efficiency and safety require that we gather observations about the characteristics of cyclists and how they behave on our road system.

Why do so many cyclists chose to ride on a sidewalk rather than on the road where they are legally required? That is one of the questions we need to answer if we are to improve cycling efficiency and safety in the Province of Ontario.

Gorski Consulting has been gathering observations of cyclists in London, Ontario for many years. These observations are permanent since they were made with video or still photos. This allows for review of the observations to extract information that was not needed at the time of the documentation. As Ontario, Canada and other nations work toward increasing cycling as a mode of travel observations of cyclist characteristics and actions become vital to understanding how to accomplish these increases in cycling volume while also improving efficiency and safety.

In recent years London Ontario, like many Canadian cities, has been building various cycling facilities. Data from several in-street sensors also suggest that cycling volumes are rising. At face value these developments appear to be good news. Yet the vast percentage of roads in London still remain geared for automotive travel. This means that the increased numbers of cyclists are riding on roadways not built to accommodate cyclists. This leads to the likelihood that increased cyclist injuries and deaths can be expected in the future.

London and Ontario have never provided a detailed and public accounting of the number of cyclist collisions that occur in their jurisdictions. One reason for this is that revealing these numbers could place responsibility on these entities for those incidents where the infrastructure has been substandard. It cannot be ignored that both London and Ontario are the defendants in many civil suits and thus they have a reason to hide safety-related problems if those problems become the source of those civil suits.  Yet, if these entities cannot be relied upon to detect and correct safety problems, who is left to do that essential work?

At no cost to the taxpayer, Gorski Consulting has been providing data to the public about a variety of road safety issues, including cycling safety, for many years. As we have no interest in the outcome of civil suits we are able to provide an independent and reliable assessment of what is occurring on our roads.

While Gorski Consulting cannot provide any information about cyclist collisions, we are able to provide a detailed study of the characteristics and actions of cyclists on London’s streets. This can help to unravel what causes may be involved in those cyclist collisions.

The table below is an example of two factors that are being tracked in our cyclist observations: cyclist gender and cyclist riding location. For a number years we have been noticing the small number of female cyclists that exist an London’s roads or adjacent to them. Similarly we have also observed that a large number of cyclists use the sidewalks of roadways rather than riding on the right edge of a lane shared with motor vehicles. The table below summarizes the status of these two factors over a nine-year period commencing in 2013.

Looking in the first column of the table we see the data referring to the years 2013 and 2021. It can be seen that there were a total of 1574 observations of male cyclists and only 277 observations of females, resulting in a total of 1851 observations.

Next we note how many cyclists were observed to be travelling on the sidewalk rather than on the road. There were 761 males and 160 females observed on the sidewalk. A limitation in this analysis is that there was no distinction made between cyclists who were walking their cycle versus riding  on it, although the vast majority of cyclists were riding. Also cyclists who were observed within a pedestrian crossing were also coded as riding on the sidewalk regardless of whether they were walking or riding. We may update the analysis on some future date to distinguish between walking and riding cyclists.

Next we have a row of the table labelled “% Female”. This is the percentage of all observed cyclists who were judged to be female, over the total number of observed cyclists, so 160/1851 = 14.96 %. All the data in the table excludes cyclists whose gender could not be identified. There were 130 cyclists in the years 2013 through 2021 whose gender could not be identified.

Next we have percentages for the males and females observed on the sidewalk. As an example the number of observed males on the sidewalk, 761 was divided by  the total number of male cyclists, or 761/1574 = 48.35 %. The same method revealed that 57.76% of females were observed on the sidewalk.

It was noted that a larger than normal number of observations were made in the year 2021 (564) compared to the nine-year total of 1851. In 2021 there also appeared to be a higher number of cyclists observed riding on sidewalks. Thus we made a column of data for the years 2013 through 2020 and a separate column for the year 2021, to show the differences. It is not clear whether the differences are genuine however it appears that the percentage of males (64.89) and females (64.94) riding on a sidewalk were higher in 2021 than the previous eight years where the males percentage was only 40.94 % and the female was 55.00 %. Differences could exist in the way that we made our observations in the earlier years such that we may not have focused as much on cyclists existing off the road surface. Never-the-less the difference is intriguing. We cannot see an obvious reason why cyclists should be using the sidewalk more often but this may be resolved with further studies.

We also created a separate column for data from the first quarter of the year 2022. Since there were only 83 observations made in this period the calculated values have likely been affected by small cell volumes. For example only 10 female cyclists were observed and 9 of them were observed on the sidewalk leading to a calculated percentage of females on the sidewalk of 90%. Clearly this value does not appear to be accurate. But we will see what develops once further data is obtained for the year 2022.

Discussion

Cyclist observation data collected by Gorski Consulting between the years 2013 and 2021 indicates that approximately 50 percent of cyclists ride on sidewalks adjacent to the streets of London, Ontario. On higher hazard roads this percentage rises dramatically. For example, from observations obtained between 2018 and 2021, along the busy, 4-lane, segment of Dundas Street between Highbury Ave and Clarke Road the percentage of sidewalk riders was noted to be 82.6 percent.

This is a view of a male cyclist riding westbound on the north sidewalk of Dundas Street near Burbick Place in December of 2021. Far more cyclists ride on the sidewalk than on the road along this busy, 4-lane segment of Dundas Street in east London.

It is peculiar that the City of London’s by-law prohibits cyclists from riding on a sidewalk unless the rider is under the age of 14. Presumably this is because it is deemed safer for children to ride on the sidewalk. Yet arguments presented by Ontario’s Ministry of Transportation in various publications emphasize the dangers of riding on the sidewalk. For example, in Ontario’s Book 18 of the Traffic Manual the following dangers of riding on sidewalks are noted.

Myth #1: Cycling on Sidewalks is Desirable

 Cycling should almost never be mixed with pedestrian traffic on sidewalks. The only exception is for children (typically under the age of 11) who may lack the necessary skills and cognitive abilities to operate a bike on a roadway with motor vehicle traffic. Cycling on a sidewalk is strongly discouraged because of the mobility constraints and varying abilities of pedestrians and cyclists. Cyclists travel at much higher speeds than pedestrians, yet they cannot change their direction or speed as quickly as a pedestrian can. There are also numerous fixed objects on or adjacent to a sidewalk around which cyclists must navigate. These include parking meters, utility poles, sign posts, transit shelters, benches, trees, fire hydrants and mail boxes. In general, cyclists should have access to dedicated or bicycle-friendly facilities. Other conflicts that cyclists encounter while riding on a sidewalk include pedestrians alighting from buses, exiting stores and emerging from parked cars. Such situations do not allow enough time for cyclists to avoid a collision. Pedestrians, on the other hand, can find it difficult to predict the intended direction of an oncoming or overtaking cyclist. When cyclists use sidewalks to travel in the opposite direction to the adjacent motor vehicle flow, conflicts occur more frequently at driveways or intersecting streets. This is because drivers who exit these areas are not looking for cyclists, who travel at higher speeds than pedestrians. The risks to cyclists are similar to those for raised cycle tracks, in-boulevard facilities and separated bike lanes described in section 5.4.1.2. However, they are amplified since the lack of a formal cycling facility and associated signing makes drivers less likely to expect cyclists to be crossing. Finally, sidewalks are typically 1.5 metres wide which is the minimum width of an on-street bicycle lane. Thus, any manoeuvring by the cyclist to avoid pedestrians, fixed objects or oncoming cyclists would require them to either stop or leave the sidewalk. In residential areas, it is common for children to ride their bicycles on sidewalks. This type of cycling is appropriate, however these sidewalks should not be signed as bicycle paths or routes.

By-laws in London Ontario require that cyclists cannot ride on sidewalks. An exemption applies for children under the age of 14.

If cycling on the sidewalk is so truly dangerous why does the Ministry of Transportation and many municipalities allow children to ride on sidewalks? Do children’s cognitive skills really become better than adults when it comes to dealing with the dangers of riding on sidewalks? Or is it that riding on the road is more dangerous than officials wish to admit.

Many cyclists can appreciate when their travel on a sidewalk could pose a safety issue to pedestrians. While discounting may be an option many cyclists can simply slow down or steer off a sidewalk briefly, at low speed, without causing any danger to a vulnerable pedestrian. It is not that cyclists are a danger on the sidewalk but that inappropriate and inconsiderate actions by some cyclists sometimes occur when better judgment is possible.

Ontario’s Ministry of Transportation and Ontario’s municipalities downplay the hazards of cyclist travel on roadways. The two photos below show an example of a typical hazard. As shown in the first photo a cycling lane comes to an end on Hale Street just south of Brydges Street in London, Ontario. The southbound cyclist must now approach a parked vehicle with no alternative but to steer left, further into the southbound lane.

Situations such as the one shown in this example are common in London Ontario where cycling lanes suddenly end and a cyclist is left to travel along a roadway which may not be designed to accommodate cyclists. Here a cyclist needs to veer out into the southbound lane to pass a parked van.

In this situation Hale Street is wider than normal, so the danger is not as great, but that is not the case along many roads in London. Veering out to pass a parked vehicle, or to avoid surface deficiencies, means that the cyclist is vulnerable to being struck by a passing motorists.

In other instances not all cycles are of the same width, especially when the cyclist is carrying cargo, as shown in the example below. Veering further into a traffic lane means that a potential is created whereby an unsuspecting motorist must steer away from the cyclist when that opportunity does not always exist.

There are many examples, such as the one shown here, where cyclists carrying cargo may be safer riding on a sidewalk rather than being exposed to being sideswiped by a passing vehicle.

There are other examples of the lack of practical understanding of how cyclists ride that results in the creation of cycling infrastructure that attempts to force riders to perform according to official dictates. In the example below the City of London created a one-way cycling track on Dundas Street in east London presumably in the belief that cyclists would follow the dictates of the signage and only travel in the direction indicated by that signage. The result, as shown in the two photos below is that cyclists just ride the “wrong” way in accordance to the way cyclists have always travelled despite what the signs say.

Here a westbound cyclist is using the south sidewalk to travel along Dundas Street near English Street in east London. A new cycling track can be seen next to the roadway but the cyclist ignores that presumably because it is signed so that cyclists can only travel eastbound, not westbound on the track.

As shown here the westbound cyclist eventually travels onto the cycling track travelling the wrong way. This is not a problem with the actions of the cyclist but a problem with the official understanding of planners of such facilities who believe they can force cyclists to act in a different manner from how they naturally behave.

Those who design cycling infrastructure must understand how cyclists behave, naturally, in the roadway environment rather than dictating that their behaviours must change. Unreasonable theoretical dictates mean that there will be conflicts and a constant need for costly enforcement to subdue cyclists to confirm with those dictates.  Many of these problems can be reduced by observing how cyclists behave in their natural state. Detailed documentations using video and still photos are objective ways of providing data of cyclist characteristics and motions. Gorski Consulting continues to provide this vital behavioral data.

OPP Place Wrong Emphasis on Story of Near-Drowning in Norfolk County

This photo posted on the OPP Twitter page fails to emphasize the danger of standing water near roadways. Sites of such standing water should to inspected to make sure that adequate barriers are installed to prevent vehicles from entering the water.

There is always a need to emphasize the importance of wearing a seat-belt because in the vast majority of cases seat-belt usage can save an occupant’s life or reduce the severity of injury. However there are instances where seat-belt use can be a problem. Those instances are when a vehicle is submerged in water or a vehicle becomes engulfed in a fire and the occupant becomes entrapped by the seat-belt. No safety device is 100% fool-proof and the public needs to have a realistic appreciation of that. And when dangers exist that could lessen the effectiveness of safety systems those dangers need to be clearly spelt out.

The OPP failed in its obligation to warn the public about the danger of a recent near-drowning when it posted the above photo along with the following comment on its Twitter account:

“A #SaturdayShoutOut to a driver in Norfolk County, whose seat belt use and quick thinking saved his girlfriend’s life. His pickup left the road, rolled into a watery ditch that submerged the vehicle. He managed to cut their seat belts and escape”

The emphasis of this story should not have been about the success of the driver who was able to cut seat-belts and allow him and his passenger to escape his submerged pick-up truck. In many instances such a success is pure luck. In many instances of such rollover even glancing blows to the head can cause an occupant to become disoriented. When a vehicle tumbles and then comes to rest upside down such an occupant can become even more disoriented and not even understand which way is up. Darkness only magnifies the problem. Water coming into the interior of an upside down vehicle can be variable in its volume depending on factors such as the status of the windows and whether they have been broken before the landing in water. Al these complications make success unpredictable and often unsuccessful. Suggesting to vehicle occupants that they can successfully escape such a vehicle with the use seat-belt cutters is not helpful. Seat-belt cutters can help but do guarantee a successful result.

A far more important point that should have been made is that standing water near any roadway can be a real danger. Therefore where ever such water exists is it essential that roads personnel, police and others who have control over the characteristics of a site, ensure that the site contains sufficient roadside safe guards to prevent or minimize that chance that an loss-of-control vehicle could exit the roadway and enter the water. In the present case the OPP should have notified the public that they had examined the site where the pick-up fell into the water and made a determination whether the site contained properly functioning roadside protection from such an occurrence. It is not helpful that the OPP Twitter post did not even mention the specific location where the pick-up truck entered the water. So no one else would capable, independent of the OPP, to inspect the site and determine if an unwarranted danger existed.

This is just another example of numerous past instances where police, who are often the only ones entrusted to investigate and reconstruct collisions, fail to document those instances where roadway problems pose an unreasonable danger to the public. There exists in the police culture that they are there primarily to charge drivers with offenses related to the Highway Traffic Act or Criminal Code and that they should have no responsibility to document roadway  safety problems. This is one of the factors that prevents many safety problems from being corrected.

Observed Female Cyclists on Streets of London Ontario Remain Low

Despite the appearance that cyclist volumes may be rising, the percentage of female cyclists observed on or adjacent to Streets in London, Ontario remain low.

Observations of cyclists in London Ontario have been made by Gorski Consulting for a number of years along various paths, trails and roads. A segment of those observations are those obtained along London’s streets. These include cyclists who may be riding within a lane shared with motor vehicles, in various cycling lanes or tracks, or on sidewalks. The observations include cyclists that may be stopped waiting at a traffic signal or walking their cycle. The following table shows the results of these observations for the first quarter of each year from 2013 through to 2022.

It can be seen that the number of observations made in the years 2021 and 2022 are greater than previous years. This may indicate that there are more cyclists on or adjacent to these streets. Alternatively we may simply having been paying more attention to documenting these instances in the last couple of years.

The last column in the above table shows the percentage of observations that were female. These percentages are taken from those where the gender of the rider was verified. So the 40 instances where gender was unknown were excluded from these percentages. Overall it can be seen that the percentage of female cyclists observed on London’s Street was found to be about 9.3 percent over the noted years of 2013 through 2022. In the earlier years of 2013 through 2016 there were less observations and the percentage of observed females was very low. This has tended to reduce the overall percentages for the combined years. Yet one can positively say that the overall percentage of female observations is certainly below 13 to 14 percent. This is a low value that does not appear to be changing even if the overall number of cyclists has grown.

If the small numbers of observations shown in our table do not invalidate our conclusions it would seem that some concern should be generated as to why there are so few female cyclists riding on London’s streets in winter conditions. Many have concluded that this is due to safety reasons and that is possible. Is inconvenience another factor? Possibly. It’s an issue that needs further discussion.

Posted Speed, Travel Speed, Impact Speed and Change-in-Speed – Do You Know The Difference?

Speed and its effects is often misreported and misunderstood as the cause of motor vehicle collisions.

There is no shortage of internet crazies with opinions on everything and a long list of brain-washed followers willing to swallow whatever is put before them. The analysis and reconstruction of collisions is no exception. While it is important that members of the public express their opinions and concerns about the collisions reported to them, there must also be a willingness to accept that those opinions may not be fully informed. As such the following is a brief discussion of one aspect of collision analysis dealing with vehicle speed. Knowing the difference between various descriptors of speed is essential if anyone wishes to provide an informed opinion on collision and injury causes.

For example, Posted Speed is the maximum speed seen posted on signage along any roadway. Often this Posted Speed is about 10 km/h lower than the “Design Speed” of the roadway. In the Province of Ontario many urban roads contain a Posted Speed of 50 km/h. On rural highways 80 km/h Posted Speeds are common, and on high speed expressways a Posted Speed of 100 km/h is common. The internet is full of “expert” opinions that road safety is dependent on the specific speed that is posted on roadside signage. Thus, if a Posted Speed of 50km/h is reduced to 40 km/h this will result in a dramatic safety benefit. Presumably the belief is that drivers are religious followers of Posted Speeds and when these speeds are reduced the speeds travelled on a road segment will also be quickly reduced. There is a naïve belief that the reduction of injuries and deaths are greatly correlated to lowering Posted Speed.

Travel (Operating) Speed is another descriptor which describes the speed at which vehicles travel on a road segment. A specific type of travel speed is the “85th Percentile Speed”, or the speed at which 85 percent of vehicle are observed to travel, at or below that speed. The 85th Percentile Speed is often used by roadway personnel to decide whether Posted Speeds are reasonably set.

In my numerous documentations of vehicle motions using multiple video cameras, I am able to obtain a very detailed assessment of the precise Travel Speed of each vehicle unit where my testing is conducted. While some variations exist, average Travel Speeds are often 10 km/h higher than the Posted Speed.  I have also observed that a good 20 percent of vehicles possess a Travel Speed that is 20 km/h or higher above the Posted Speed. The greatest difference between Posted Speed and Travel Speed that I have documented is on the 400-Series expressways of Ontario where, in some locations and at certain times, Travel Speeds of 130 km/h are not uncommon.

There are common postings on various social media sites that Travel Speed is directly proportional to the severity of injury and probability of death. The commonly held view is that a vehicle travelling at a certain speed will result in a certain severity of injury or a certain probability of death. These generally accepted points of view never provide the specific basis for these conclusions. Whatever research has been conducted the travel speed of a vehicle would be a difficult parameter to determine unless it was obtained from event data recorders. And it has never been revealed which research has specifically used this source as the basis for determining Travel Speed.

A more reliable parameter in terms of predicting injury causation and probability of death has been the Impact Speed of a vehicle. Travel Speed and Impact Speed are not the same. A vehicle may be travelling at 80 km/h and, without any interventions, may possess an impact speed of 80 km/h. Yet in another instance of a vehicle travelling at 80 km/h the driver may apply his brakes reducing the vehicle’s speed to 40 km/h at impact. Those two scenarios are vastly different in terms of injury/death potential. Meanwhile the concept of “velocity” is put into play when we consider the directionality of that impact speed. Two vehicles coming into a full-over-lap head-on collision at 80 km/h have the potential of causing much more injury and death than two vehicles travelling at 80 km/h and approaching from intersecting roadways. We then must consider, not only the Impact Speed of the vehicles but the Change-in-Speed, or more precisely the “Change-in-Velocity” of those vehicles as a result of the impact.

If Posted Speed, Travel Speed and Impact Speed were such complete predictors of injury and death, federal agencies such as the U.S. National Highway Traffic Safety Administration (NHTSA) or Canada’s Transport Canada would have used these parameters in their decades of inquiry into the mechanisms of injury. But that is not the case. On a general level NHTSA determined long ago that, over a broad number of collisions, the documentation of collision evidence for the purpose of calculating a Change-in-Velocity (or Delta-V) would be a useful exercise. Therefore hundreds of investigators spent numerous hours measuring the extent of crush on vehicles, estimating the stiffness of those involved structures and then calculating the Delta-V experienced by those vehicles. Upon completing that process investigators would also document the specific evidence of occupant contact visible in the vehicle interior or exterior. By obtaining reliable medical information on the specific injuries sustained by involved persons, investigators could then match the injury to its source. Now a second process of considering the “Second Collision”, that is the collision between the human body and the vehicle, could be begun. So not only is it important to calculate the Delta-V of the collision-involved vehicle, but the calculation of the severity of impact between the human body and the vehicle is equally important, if not more so. And, eventually, the calculation of a third collision, which is the collision of the internal organs of the body within itself is completed. It is the acceleration, or the rate of change in velocity, that describes how injuries differ from one instance to the next. And further, it is the rate of change in acceleration, or “Jerk” which has a further influence.

So, understand that Speed, in whatever way it is described, can be a useless value in understanding how and why collisions occur and how injuries and deaths occur. Speed has really nothing to do with injury causation or death except that, in a sense, Speed creates the potential for injury because it is what causes vehicles and persons to possess kinetic energy that must be dissipated. Dissipation in a controlled manner is what is desirable and this is accomplished in many ways through the design of vehicle structures, the use of safety devices such as seat-belts and air bags and through the design of the highway structures that extent the time of vehicle deceleration while also reducing the possibility of intrusions into the occupant space or reducing the chances of unpredictable chaos when vehicle rollover is initiated.

Yes, when an inappropriate Travel Speed is chosen by a driver that can increase the probability that a collision may occur. But that has nothing to do with what severity of collision will occur. There are far too many factors involved in this relationship to enable Travel Speed to be used as a useful predictor of injury or death.

Additions to Road Data Webpage of Gorski Consulting Site

Road conditions are a factor in the causation of motor vehicle collisions. An objective method of comparing one road to another is the objective of the data contained in the Road Data webpage of the Gorski Consulting website.

The Road Data webpage has been updated on the Gorski Consulting website to explain additional testing that has been conducted in recent years.

As a result of an unexplained hacking of the Gorski Consulting website in early January, 2022 we have removed our hosting account from Godaddy to a more local company, Nerds-On-Site. Mr. Mike Barry of Nerds has been very helpful with this transition and has been patiently explaining how Gorski Consulting site will operate with their firm.

One of the complications is that the data files on the Road Data webpage may become unlinked and these links will likely need to be re-connected shortly. As a result of this need it became apparent that the text on the Road Data webpage has not been updated for quite some time. So this has been the impetus to update our text along with explanations of what additional testing has been completed and uploaded to this page.

If you now visit the Road Data webpage there will be new additions of data regarding testing from 2021. This testing involved driving an 18-passenger school bus over speed bumps in a number of locations throughout London. The purpose of this testing was two-fold: to demonstrate how the motions of the bus might be comparable to the previous testing using a passenger car, and secondly, to demonstrate what reactions are caused to vehicles which pass over speed bumps.

Another set of data includes testing with two school buses, a full-size school bus and an 18-passenger school bus, over a number of roads in London, Ontario. This data should demonstrate that, although small differences occur in the vehicle motions, there does not appear to be a major difference in the data whether  the testing vehicle is a passenger car or something very different such as a full-size school bus. Thus the methodology that we have employed over the years appears to be valid and can provide an indication of the “goodness” or “badness” of the road regardless of what kind of test vehicle is used in the testing.
