background: fatalities from road traffic crashes (rtcs) are a public health challenge for low- and middle-income countries, especially those experiencing epidemiological transition. this paper aims to describe demographics and trend analysis of fatalities of rtcs in oman from 1995 to 2009. methods: the rtc data from 1995 to 2009 were obtained from the published reports of the royal oman police ...

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...

While rural freeways generally have lower crash rates, interactions between driver behavior, traffic and geometric characteristics, and adverse weather conditions may increase the crash risk along some freeway sections. This paper examines the safety effects of roadway geometrics on crash occurrence along a freeway section that features mountainous terrain and adverse weather. Starting from pre...

In recent years the development and use of crash prediction models for roadway safety analyses have received substantial attention. These models, also known as Safety Performance Functions (SPFs), relate the expected crash frequency of roadway elements (intersections, road segments, on-ramps) to traffic volumes and other geometric and operational characteristics. A commonly practiced approach f...

The reduction of traffic crashes, as well their socio-economic consequences, has captivated the attention safety professionals and transportation agencies. most important activity for an effective road practice is to identify hazardous roadway areas based on a spatial pattern analysis crashes evaluation crash relations with neighboring other relevant factors. For decades, researchers have adopt...

backgrounds and aims: the tehran province was subject to the second highest incidence of fatalities due to traffic accidents in 1390. most studies in this field examine rural traffic accidents, but this study is based on the use of logit models and artificial neural networks to evaluate the factors that affect the severity of accidents within the city of tehran. materials and methods: among the...

Road traffic injuries (RTIs) are the sixth leading cause of deaths in India and about 400 deaths take place every day due to road traffic accidents. The present paper analyses the data of the India’s National Crime Record Bureau (NCRB) to assess the burden of RTI. In addition, it reports the health systems research initiated by the Indian Council of Medical Research (ICMR). As per NCRB data, in...
