In this thesis the lateral performance of heavy vehicle combinations, specifically longer combination vehicles, is discussed. The use of longer combination vehicles is promoted by their positive impact on the traffic congestion problem, as well as their economic and environmental benefits due to reduced fuel consumption and emissions. However, from a safety perspective, ther...

Vehicle design features that enhance safety can mitigate older driver frailty and declines in ability. We have investigated the older driver’s perception of vehicle safety and how this influences their vehicle purchase. Focus groups (n = 27) were conducted among drivers aged 70-90 in South-Western Ontario. Questions focused on participants’ perceptions of vehicle safety and design, the vehicle ...

Older drivers are at risk for vehicle crashes due to impairments of visual processing and attention, placing these drivers at greater risk in driving tasks that require continuous attention to neighboring traffic, especially lead vehicles (LVs). We investigated car following behavior in 42 younger drivers (ages 18 to 44 years) and 58 older drivers (ages 65 to 86 years) in a driving simulator. T...

We present a microscopic driving algorithm that prescribes the acceleration using three parameters: distance to leading vehicle, next traffic light and nearest stopping point when is in red phase. apply this construct decision trees enable two behaviors: aggressive careful. The focus of study analyze amount drivers are needed order generate gridlock portion city with signalized intersections. A...

OBJECTIVE The initial months of licensure are especially hazardous for teenagers. Factors leading to crashes of novice 16-year-old drivers were identified. METHOD Sixteen year-olds in Connecticut who were involved in nonfatal crashes during the first 8 months of licensure were interviewed, and police crash reports were examined. Crash types and contributing factors were identified. RESULTS ...

This paper presents the results of a field test evaluating drivers’ decision making and gap acceptance for a left turn maneuver with opposite traffic; with a focus on the scenario where the turning vehicle is approaching the intersection. Twenty-three participants drove an instrumented vehicle ten times around an extended block turning left at four specific intersections. DGPS and radar data we...

With 2003 Fatality Analysis Reporting System data, we examined relationships among predictors of motor vehicle injury/fatality outcomes for younger (35-54 years) and older (65 years and older) drivers. Using the Precede-Proceed Model of Health Promotion as an organizing framework, we classified variables into person, vehicle and environment domains and conducted a multinomial logistic regressio...

Most of drivers have to compensate small directional deviations from the desired driving path when disturbances such as crosswinds, overtakings, road irregularities and unintended driver inputs  are imposed. These types of deviations have a tiring effect on driver and traffic’s safety and should be minimised. To increase the understanding the influence of vehicle’s properties in crosswind and o...

harm by either a driver or passenger of one vehicle directed against the occupants of another vehicle or pedestrians entail road rage and could potentially lead to involvement in collisions, injuries, and death.1-3 Road rage has also been associated with psychiatric illnesses in both the victims and the perpetrators.4 A previous study reported that the most common type of road rage experience o...
