Testing the Aggressiveness of Speed Bumps
Are some speed bumps too aggressive? Are all speed bumps created equal”? Testing by Gorski Consulting provides some answers.
A new article has been posted by Gorski Consulting that discusses the results of testing of an aggressive section of speed bumps located on Edmonton Street in London ,Ontario, Canada. A test vehicle was driven over the bumps at moderate speeds of about 30 km/h and the resultant longitudinal and lateral rotations of the test vehicle were obtained. This new data adds to the increasing body of data that already exists on the Road Data webpage of the Gorski Consulting website.
Bicyclist And Pedestrian Safety In Jeopardy Along Latest Path In London Ontario
At face value this curve of the new bicycle path appears to travel over a newly constructed bridge in a safe manner – but there is a problem.
It is as if designers of bicycle paths have never ridden a bicycle before. Such appears to be the case at the latest addition to a multi-use path being completed in East London, Ontario.
The extension of the multi-use path system in London has to be hailed as a much-needed improvement. For many years the path system formed a “Y” where the centre of the arms of the letter was positioned at the City’s downtown. The two upper arms of the “Y” are located in the north and south sections of East London. With a recent, short extension of one of those arms toward the other it would appear that the City is attempting to connect them and therefore form a ring around the City. And this approach is commendable. But someone seems to have forgot about bicycle safety.
In the vicinity of Trafalgar St. the new extension of the path was designed to travel beneath Trafalgar at the same location where the pre-existing bridge crossed over Pottersburg Creek. It was not a bad idea to simply run the new path within the same location as the creek. But the implementation of that decision led to a mistake in design which now plagues the safety of both bicyclists and pedestrians.
The photo below shows a view looking north at a newly constructed bridge that carries the new path over to the east side of Pottersburg Creek before abruptly changing direction so that the path will go underneath the pre-existing bridge of Trafalgar Road.

Below is a northerly view at a point just past the newly-constructed bridge. If bicyclists intend to continue using the path they must make a sudden left turn to travel underneath the pre-existing bridge at Trafalgar Road.
This northward view is just past the newly-constructed bridge where bicyclists wanting to continue on the path must make a sudden left turn underneath the pre-existing bridge at Trafalgar Road.
Another view shown below is from the top of the pre-existing Trafalgar Road bridge and here we can see the new bridge at the extreme right of the view and how cyclists will need to make a sharp left turn to go underneath the pre-existing bridge.

What is not obvious in these photos is that there is a persistent downslope in the several hundred metres leading up to the T-intersection. Anyone who is familiar with bicycling will appreciate the very large effect that vertical slopes have on the speed of bicycles. Thus bicyclists crossing the newly constructed bridge will likely be travelling a higher than average speed due to the downslope.
What may also not be readily apparent is that there is a washout of loose gravel and dirt in the above photo that has deposited loose material onto the path precisely where there is a steep down grade and cyclists must make a sharp turn to go under the pre-existing bridge. The extent of the loose material is more visible in the additional photo below.
The photo below shows another view of the new path as it travels underneath the pre-existing bridge. A sharp right turn is required to travel underneath the bridge precisely at a point where the loose gravel and earth have slid down onto the path surface. Even though this debris may be cleared from time to time it will undoubtedly become a continual problem.

If this location was only for one-way travel the problem would not be as great. But as can be seen in the southward view below, various pedestrians and other cyclists will be travelling toward this blind spot and will undoubtedly crash with the northbound cyclists because there is not a sufficient line of sight provided.

The designers of paths for pedestrians and cyclists seem to not understand that the various safety systems of design that exist on roadways must also apply to multi-use paths. Lines of sight, stopping distances, controls of vertical and horizontal alignment, signage, and surface conditions are just as important on these paths. Even at a speed of 25 km/h a cyclist colliding with a frail pedestrian or child can cause significant injury. Similarly a cyclist travelling at that seemingly slow speed can sustain serious injury when impacting an forgiving roadside object or from simply falling onto a hard surface.
Unfortunately, it has been our experience that the courts in Ontario have demonstrated a propensity to protect those responsible for creating unsafe path and road conditions for cyclists resulting in many unsafe scenarios that need not exist.
Canadian Association of Journalists Support Aylmer Express Journalists
The London Free Press has reported that the Canadian Association of Journalists is condemning the Ontario Provincial Police for their actions in charging two Aylmer Express journalists with respect to an incident that occurred in June of 2017 involving the death of a driver who drove his vehicle over a cliff of Lake Erie. The circumstances as to how and why the incident occurred was not clear as reports of the OPP involvement in a pursuit of the deceased’s vehicle were confusing, at best. The two charged journalists, John Hueston, and his son, Brett, were involved in some kind of verbal altercation with police when they tried to take photographs near the site where the plunge took place. It is likely that a trial, reportedly commencing on Wednesday, June 27th, will provide some clarification as to why charges against the two were necessary. The summary of the incident as reported by the London Free Press, suggested that the police actions were excessive and unnecessary.
The issue has been raised on numerous occasions involving police actions. A full, detailed and independent assessment of police actions is often unavailable to the public. The involvement of independent journalists who can provide an objective assessment of police actions has been a fundamental cornerstone of western democracy. It cannot be overstated that when issues of significant importance to society need to be illuminated there has to be an independent voice to present that view.
At the time of the incident Gorski Consulting had also expressed concern over the confusing report of how the driver came to his death. A news article was prepared summarizing the inconsistencies in that information. Subsequently that news article has now been uploaded to the Articles page of this Gorski Consulting website.
Highway 401 Median Cross-over Fatal Collision Near Chatham Ontario
A high-tension cable barrier will be installed along the 119 kilometer stretch of Highway 401 between Tilbury and London, Ontario. This decision has already been made and construction is already underway. Its effectiveness however will remain questionable on a highway that contains so many large and heavy trucks. Just this past week, on June 22, 2018, a tractor trailer travelled through the median and collided with another truck resulting in fatal injuries to one of the truck drivers. It has not been definitively proven that the proposed high tension cable barrier will prevent such a collision from occurring. A cable can gain its strength of its length while being anchored at many locations and providing some level of deflection. However many loaded tractor trailers could weight as much as 80,000 pounds. Deflecting such a large mass may prove challenging when the truck’s angle of departure increases. Also, as has been proven in many instances, relatively minor impacts to installations are often left unrepaired and over time the initial strength of such a system becomes weakened.
There is little or no independent supervision of the agencies that provide maintenance to the systems. Police whose duty it should be to protect the public from all highway hazards, regardless of their origin, simply do not understand that their duty must include the protection of the public from hazards caused by roadway deficiencies.
There are many concerns with respect to the reporting of the results median cross-over collisions. The public that is expected to elect their political representatives must have a clear understanding of the safety issues so that they can inform their political representatives of what they expect. When the public is uninformed it makes the wrong requests. Thus a proper degree of public information about how highway systems are performing is essential.
Charges Against Aylmer Express Newspaper Journalists An Appalling Abuse of Democracy
For years Gorski Consulting has expressed the opinion that the public needs to be made aware of the manner in which persons have perished in motor vehicle incidents. It has been our continual criticism that investigating police do not provide sufficient information about those deaths and the mainstream news media are often handicapped with the lack of funds to provide quality journalism that digs deeper than what they are simply told to report by police.
Over the years we have been impressed with the quality of reporting by the very small Aylmer Express newspaper located in Aylmer, Ontario. On a number of occasions, when the large mainstream organizations did not provide sufficient detail surrounding a motor vehicle collision, we found that the Aylmer Express filled in those details. We often wondered how such a small outfit could provide such quality journalism that the larger outfits could not.
It is with great distress that we have learned that these high-quality journalists have been charged with respect to the high-quality activities that they have engaged in by attempting to obtain information about how a driver came to his death upon driving over a cliff of Lake Erie on June 23, 2017, not too far from Aylmer, Ontario.
In fact, Gorski Consulting was also concerned about the reported information about the death such that we prepared an article on the incident and posted the article on our Articles page of this website. The circumstances by which the death was reported did not make sense and we totally understand why the Aylmer Express journalists would seek to attend the site where the driver perished to learn whether the police were involved in a chase that ultimately led to the driver’s death.
It was only through the actions of the London Free Press that published an article in their digital website that we learned of the charges to these journalists. Without that action no one would have known that these charges took place. We understand that every incident has its divergent reporting of facts. However the London Free Press article was disturbing in the way it reported the police actions that appeared to be highly inappropriate. The journalists, John Hueston, publisher, and his son Brett, apparently crossed over a road-closed sign on the roadway to get closer to the collision site where the driver perished. While taking photos of the recovery operations they were reportedly approached by a plain-clothed female offer and subsequently by her superior, that, through a verbal exchange, led the journalists to be charged with “criminal obstruction of a police officer”. Again, the facts as reported by the London Free Press may be different than reality and the true facts may be revealed in court. However, if the facts are as reported, they truly represent a challenge to democracy and the freedom of the press which is so vital to it.
What is at stake at the upcoming trial that will commence in St. Thomas, Ontario on June 27, 2018, is not just the damaging of the reputations of these high-quality journalists. What is at stake is the fundamental right of the public to be provided with independent information about the “5 Ws” of any incident (Who, What, Where, When and How, or something to that effect). Independent reporting beyond what the public is told by the government, its police, or other agencies in charge, has long been crucial to the ideals of democracy that guarantee a balancing of power. The tipping of that important balance can lead to far more unpleasant outcomes than the result of a simple trial.
We will be watching closely for the result of that trial. But more importantly, we emphasize the importance of freedom of expression and the absolute necessity that the public be informed of important matters that the public has a right to know. When the public is simply told what it is to know this is a recipe for disaster. Independent journalism is absolutely essential to our stable and secure way of life that we have enjoyed for many generations.
