Over the past several years, numerous essays have examined the deterrent effects of aggressive police patrol strategies like traffic law enforcement (Jacob and Rich, 1981; Sampson and Cohen, 1988; Wilson and Boland, 1978, 1981). This essay continues this line of research. It reports on the results of a field experiment in Dayton, Ohio, designed to measure the effects of traffic law enforcement ...

background: in chile, a new law introduced in march 2012 lowered the blood alcohol concentration (bac) limit for impaired drivers from 0.1% to 0.08% and the bac limit for driving under the influence of alcohol from 0.05% to 0.03%, but its effectiveness remains uncertain. the goal of this investigation was to evaluate the effects of this enactment on road traffic injuries and fatalities in chile...

OBJECTIVE To estimate the effect of a new road traffic law against alcohol-impaired driving in Japan. METHODS Japan passed a new road traffic law in June 2002 intended to reduce alcohol-impaired driving by decreasing the permissible blood alcohol level and by increasing penalties. Using data collected from police reports, the number of traffic fatalities and injuries were analyzed by time ser...

background and aims: this study aimed to evaluate the effect of enforcement of new traffic laws on the fatal and non- fatal injury rates in iran. methods: in a longitudinal, interventional controlled trial study, all subjects with history of fatal and non-fatal injuries were studied. their injuries were caused by six risky violations (unauthorized speed, illegal overtaking, red traffic light cr...

objectives: to determine the behavioral pattern of golestan university of medical science (gums) students as pedestrian and car occupants in relation to traffic law based on health belief model. methods: this cross-sectional study was performed during 2012 in gums. a total of 370 students of gums were selected using multi-stage sampling method including stratified and random sampling. data were...

In this paper we develop optimal control laws for traffic networks. A standard traffic flow model is used to formulate the traffic control in terms of " on-off " strategy for the traffic signals. It is of the form of the optimal bilinear control problem with the binary constraints. We develop a Lyapunov function based feedback law for minimizing traffic congestions and stabilizing the traffic f...

background and aim : about one-third of iranian children mortality is caused by injuries from which 36% occur due to road traffic injuries. using child restraint embedded in vehicles can reduce road traffic fatalities by 71% for neonates and 54% for children. based on its effectiveness in reduction of fatality and prevention of injury severity, child restraint usage mandatory law is a priority....
