Scholarly information regarding some aspect of traffic safety.

RESEARCH - The Transition to Unsupervised Driving

New Driver SignsThis study released by the AAA Foundation for Traffic Safety is based on a small group of teen drivers using a vehicle equipped with an event data recorder called Drivecam.

RESEARCH - The Nature of Errors Made by Drivers

Austroads LogoHuman error is responsible for between 75% and 90% of crashes, but this report from Australia suggests that the system that a driver makes the error within needs to be more carefully examined. The system either contributes to the error or shapes the driver's behaviour that produces the error.

RESEARCH - Seatbelts on the School Bus

School BusI am frequently asked why school buses don't have seatbelts. The Alabama School Bus Seat Belt Pilot Project put seatbelts in school buses and studied their benefits. The study found a wearing rate of just under 62%. This resulted in, on average, saving 0.13 lives and 7.60 injuries per year. The seat belts were 39% effective in reducing fatalities and 13% effective in reducing injuries.

RESEARCH - Are Older Commercial Vehicle Drivers a Safety Risk?

Truck TractorCommercial Truck and Bus Safety Synthesis Program (CTBSSP) Synthesis 18: Older Commercial Drivers: Do They Pose a Safety Risk? explores age-related changes in the basic functional abilities needed to drive safely. The report is designed to help assist industry and labor practitioners in promoting safer commercial operations.

RESEARCH - Human Factors Guidelines for Road Systems

NCHRP logoThis report produced by the US Transportation Research Board's National Cooperative Highway Research Program (NCHRP) explores human factors principles and findings for consideration by highway designers and traffic engineers.

RESEARCH - Shoulder and Centerline Rumble Strips

NCHRP LogoTRB's National Cooperative Highway Research Program (NCHRP) Report 641: Guidance for the Design and Application of Shoulder and Centerline Rumble Strips explores the design and application of shoulder and centerline rumble strips as a crash reduction measure, while minimizing adverse effects for motorcyclists, bicyclists, and nearby re

RESEARCH - Design and Evaluation of Effective Crosswalk Illumination

The City College of New York's University Transportation Research CenterIt's amazing how complicated that it can be to decide on the best way to light a crosswalk. The design must provide illumination of pedestrians so that they can be seen at night, be easy to maintain, cost effective and not cause glare that would interfere with the driving task. This study by a group of scientists from the Rensselaer Polytechnic Institute examines the issue and settles on fluorescent lamps mounted in bollards at each end of the crosswalk.

RESEARCH - Driving While Fatigued

Truck TractorDriver fatigue is an important causal factor in many highway crashes—and is of particular concern in the trucking industry where many operators undertake long haul drives with limited amounts of sleep. Previous studies suggest that fatigue can affect steering performance and speed control.

RESEARCH - British Columbia Roadside Survey 2008

CCSA Logo"A random survey of drivers was conducted at pre-selected locations in British Columbia from Wednesday to Saturday nights in June 2008. The purpose was to collect information on the prevalence of alcohol and drug use among nighttime drivers. Those surveyed were asked to provide a voluntary breath sample to measure their alcohol use and an oral fluid sample to be tested subsequently for the presence of drugs."

RESEARCH - Driving While Ill is Impairing

Lloyd's TSB LogoLloyd's TSB Insurance commissioned a study that suggests driving with a cold or the flu can impair a driver by up to 11%, comparable to having consumed a double of hard liquor. A single sneeze lasts about 2 seconds, during which the driver's eyes are closed.
