Scholarly information regarding some aspect of traffic safety.

RESEARCH - Effectiveness of Painted Stop Lines

Stop Line

If there is a marked stop line at an intersection controlled by a stop sign, drivers (and cyclists) are required to stop at that line. This rule is probably almost universally ignored in favour of stopping in a position where the driver can see cross traffic that would require them to yield. Of course, many drivers choose not to stop at all.

MOTORCYCLES - Saw But Forgot

motorcycleOne of the most common motorcycle crashes occurs when another road user moves into the path of the oncoming rider. These collisions are often called Look But Fail to See (LBFTS) or Sorry Mate, I Didn't See You (SMIDSY). Recent research suggests that the failure to yield could also be resulting from a memory deficit or Saw But Forgot errors.

RESEARCH - Understanding ADAS

AAA LogoComplex automation known as advanced driver assistance systems (ADAS) can now control the vehicle’s speed, headway, and lane position, and capabilities continue to expand. Drivers need to understand these new vehicle features in order to use them effectively and appropriately.

RESEARCH - Safety Evaluation of Pedestrian Countdown Signals

Pedestrian Countdown SignalHere's a document from the US Federal Highway Authority that looks at the safety benefit of pedestrian countdown signals. The study results showed that after the implementation of these signals, pedestrian crashes decreased by 9 percent, total crashes decreased by 8 percent and rear-end crashes decreased by 12 percent.

RESEARCH - Speeding is Best Predictor of Crash Risk

speed demonThe University of Waterloo has identified speed as the best predictor of crashes after analyzing data from onboard devices in vehicles. The research examined four aggressive driving behaviours, speeding, hard braking, hard acceleration and hard cornering for possible links and the likelihood of crashes. Of the four, only speed was statistically significant as a strong predictor of crashes.

RESEARCH - More Than Paint Needed to Keep Cyclists Safe

painted cycle laneResearch by Dr. Ben Beck at Australia's Monash University collected data on 60 cyclists in Melbourne who rode their bicycles with a custom device (the 'MetreBox') installed to quantify the distance that motor vehicle drivers provide when passing them. More than 18,000 vehicle passing events from 422 trips were recorded.

RESEARCH - Bike Friendly Cities are Safer

CyclistA report from the Mountain - Plains Consortium answers the question of why bike friendly cities are safer for all road users. From the document abstract:

Despite bicycling being considered on the order of ten times more dangerous than driving, the evidence continues to build that high-bicycling-mode-share cities are not only safer for bicyclists but for all road users. This paper looks to understand what makes these cities safer.

RESEARCH - Raising Rural Speeds Also Raised Collision Numbers

120 kmh speed signSome sections of rural highways in British Columbia saw an increase in the posted speed limit in 2014 following a provincial government review which included a poll of the population. Within two years some of these increases were rolled back due to rising collision rates. Today a research report released by academics from the University of British Columbia evaluates the effect that the initial speed increases have had since they were implemented.
