Microscopic computer models provide the opportunity to simulate vehicle and pedestrian behaviour under varying infrastructure conditions. Pre-crash and crash involvement risk at street, or even suburb level, can be explored and modified through various scenarios, such as: traffic calmed streets, pedestrian crossings, technology based infrastructure and other physical interventions. Models can s...

BACKGROUND Road traffic injury is a major cause of death among youths. AIMS To estimate mortality differences in family socioeconomic position (SEP) and municipal disadvantage level. METHODS Data on all Norwegians born in 1967-76, gathered from national registries, were linked by a unique national identification number. The 611 654 participants were followed-up for 5 years from age 16 years...

Run-off-road crashes have been identified as a major concern for automobile safety and several advanced driver assistance systems (ADASs) targeting run-off-road crashes are on the market today. Assessment of ADASs require relevant test scenarios and valid computational models of driver behaviour. Therefore, the objectives of this thesis has been: (A) define run-off-road test scenarios, and (B) ...

The limited quality of location data poses a major problem to those who want you use these data for research or safety management. A considerable proportion of crashes remain unassigned to specific road locations. This fact is sometimes overlooked because crash database queries return crashes assignable to locations but do not issue warnings about crashes that are not assignable. Without reliab...

OBJECTIVES Motor vehicle-pedestrian crash is a significant public health concern. The urban campus of Georgia State University poses unique challenges due to a large number of students and university employees. The objectives of this study are twofold: 1) to examine the correlation between specific features of the built environment on and around the University campus and pedestrian crashes; and...

BACKGROUND In the early 2000s, electronic surveillance systems began to be developed to collect and transmit data on infectious diseases in low-income countries (LICs) in real-time using mobile technologies. Such surveillance systems, however, are still very rare in Africa. Among the non-infectious epidemics to be surveilled are road traffic injuries, which constitute major health events and ar...

The road environment can affect driver speed choice through influencing both the driver’s perception of their current speed, and the speed that they think is appropriate for the road. These influences and their effects on speed can therefore affect crash rates. This report reviews the influence of various factors within the road environment, including the geometry of the road, the roadside envi...

Nilsson (1981) proposed power relationships connecting changes in traffic speeds with changes in road crashes at various levels of injury severity. Increases in fatal crashes are related to the 4(th) power of the increase in mean speed, increases in serious casualty crashes (those involving death or serious injury) according to the 3(rd) power, and increases in casualty crashes (those involving...
