The 24/7 Sobriety Project requires those arrested for or convicted of alcohol-related offenses to take twice-a-day breathalyzer tests or wear a continuous alcohol monitoring bracelet. Those who fail or skip their tests are immediately subject to swift, certain but modest sanctions—typically a day or two in jail.
Drivers 65 and older are only 16 percent more likely per mile driven to cause a traffic accident than are drivers ages 25–64. And their total contribution to the nation's traffic accidents is surprisingly small, writes David S. Loughran.
Reviews a wide variety of evidence regarding traffic safety in the United States, with specific reference to military personnel, focusing on safety interventions and attempts to change driver behavior and decisions.
This report describes a method for modeling an emergency response system; identifying how individual parts of the system might fail; and assessing the likelihood of each failure and the severity of its effects on the overall response effort.
This study investigated the applicability of Multinomial logit (MNL) models to predict the proportion of crashes by collision type and to estimate crash counts by collision type.
A comprehensive look at Los Angeles traffic debunks common myths about the metropolitan region's traffic patterns and details the reasons why congestion is so bad -- and why it will get worse in the coming years without significant policy changes.
This research brief identifies key factors determining L.A. transportation policy needs and makes 13 recommendations that together could reduce congestion -- arguably the worst in the country -- substantially within five years.
The authors of this book recommend strategies for reducing traffic congestion in the Los Angeles area that could significantly enhance quality of life, reduce economic and environmental costs, and improve social justice within about five years.
RAND Study Finds Senior Drivers Less Likely than Youngest Drivers to Cause Accidents.
This research brief summarizes a study that concludes older drivers are relatively safe and that targeting restrictive licensing policies at that group will do little to improve overall traffic safety.
This paper summarizes the findings and policy implications of a study estimating the relative riskiness of older drivers, concluding that stricter licensing policies targeting that group would likely not improve traffic safety substantially.
Published commentary by RAND staff: Green But Unsafe, in Wall Street Journal, Europe Edition.
Investigates the possibilities of implementing instruments developed in the United States, such as SafeStat, to increase road traffic safety, and investigates developing a similar instrument for prioritizing carriers for inspection in the Netherlands.
Study refutes a common criticism of no-fault auto insurance -- that it may increase the accident rate by reducing drivers' incentives to drive carefully.
A model for analyzing traffic accidents that relates unsafe driving to operational and environmental variables, the production of injuries and property damage, and the safety measures that might reduce the incidence and severity of accidents.
A survey of the literature on medical problems and physical fitness as they relate to the occurrence of traffic accidents.
