Data Science (DSCI) 490 Capstone Research Guide

Transport Canada’s National Collision Database (NCDB) contains data on all reportable motor vehicle collisions in Canada that the provinces and territories provide each year.

Your vehicle’s tires are engineered to perform safely, day in and day out. But to do their job right, tires need regular maintenance. This pamphlet
provides the information you need to maintain your tires properly.

The goal of RoadSafetyBC and its partners is to end deaths and serious injuries on British Columbia’s roads. The data published on this page supports that goal.

Most new cars come with All-season tires.

Peer Reviewed Article - There are many accidents in road traffic involving both heavy goods vehicles and passenger vehicles, and the interpretation of the causes of some accidents can be very difficult. The paper presents the results of an analysis of the road accident causes involving a truck and two passenger cars. The hypothesis was verified that the incident took place after the damage to the front wheel of the truck, which resulted in an uncontrolled change of the direction of its travel and leaving the lane in the opposite direction of the passenger cars. The damaged tire was inspected, and traces were described in the form of cracks on the side surface, irregular abrasion on the central part of the side surface and near the bead, as well as deformations resulting from damage to the cord. The thesis was made that the tire cracked as a result of its material structure defects. In order to verify it, bench tests were carried out on the deformation of the tire sidewall at various load conditions, which simulated driving with too little air pressure in the tire. Detailed studies of the fracture of the tire sidewall and the wires that make up its steel cord were carried out. Macroscopic examination of the cord wires on eight samples revealed the presence of corrosion changes that should not occur under normal operating conditions. The results of the research work indicate that tire rupture was caused by delamination of the material coatings and corrosion of the steel cord wires. These defects could have arisen due to the earlier cracking of the rubber layer and the ingress of moisture or as a result of the use of corroded steel cord wires in tire production. In the analyzed case, the driver could not regain control of the vehicle and avoid a collision with oncoming vehicles.

Since excessively worn tires pose a significant risk to vehicle safety, it is crucial to monitor tire wear regularly. This study aimed to verify the efficient tire wear prediction algorithm proposed in a previous modeling study, which minimizes the required input data, and use driving test data to validate the method. First, driving tests were conducted with tires at various wear levels to measure internal accelerations. The acceleration signals were then screened using empirical functions to exclude atypical data before proceeding with the machine learning process. Finally, a tire wear prediction algorithm based on a 1D−CNN with bottleneck features was developed and evaluated. The developed algorithm showed an RMSE of 5.2% (or 0.42 mm) using only the acceleration signals. When tire pressure and vertical load were included, the prediction error was reduced by 11.5%, resulting in an RMSE of 4.6%. These findings suggest that the 1D−CNN approach is an efficient method for predicting tire wear states, requiring minimal input data. Additionally, it supports the potential usefulness of the intelligent tire technology framework proposed in the modeling study.

As the fall colours pop and winter looms, many folks are - or should be - thinking about their vehicle's winter footwear, whether it's getting swapped on a seasonal set of tires they already have, or it's purchasing tires to see them through winter's cold and whatever white stuff comes our way.

Top executives from motor company Ford and tire manufacturer Bridgestone/Firestone were summoned before a congressional panel to explain their roles in a safety crisis over tire shredding. Appearing before the panel, Masatoshi Ono, Bridgestone's chief executive, said he accepted “full and personal responsibility” for the recall of 6.5 million tires, found mainly on Ford Explorers. He added, however, that his company could not find a design effect that was causing tread to wear away at high speeds. In his testimony, Jacques Nasser, Ford's chief executive, blamed Firestone, saying his company did not know there were defects with the tires until it eventually secured the claims data from Firestone and analyzed it. The rapidly escalating safety crisis has already claimed the lives of 88 Americans.

Ford Motor Co. CEO Jacques Nasser announced Tuesday that 13 million Firestone Wilderness tires would be recalled at a cost of $2-billion (U.S.), doubling the number that was taken back last summer after they were linked to deadly accidents.
