Title: TRANSFERABILTY AND CALIBRATION OF THE HIGHWAY SAFETY MANUAL PERFORMANCE FUNCTIONS AND DEVELOPMENT OF NEW MODELS FOR URBAN FOUR-LANE DIVEDED ROADS
Road traffic crashes in Gulf Cooperation Countries (GCC) is considered a serious problem that has deep effects on GCC's population as well as on the national productivity through the loss of lives, injuries, property damage and the loss of valuable resources. Thus, there is an urgent need to alleviate the Severity of the traffic safety problem in GCC, which in turn will set a prime example for ...
متن کاملExploring a Bayesian hierarchical approach for developing safety performance functions for a mountainous freeway.
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...

متن کاملExploring the transferability of safety performance functions.
Safety performance functions (SPFs), by predicting the number of crashes on roadway facilities, have been a vital tool in the highway safety area. The SPFs are typically applied for identifying hot spots in network screening and evaluating the effectiveness of road safety countermeasures. The Highway Safety Manual (HSM) provides a series of SPFs for several crash types by various roadway facili...
متن کاملSafety Functions in Railways
There are several ways to describe and structure safety rules for railways, and a few examples are given in the report. A tentative holistic framework for describing safety features in relation to safety rules is presented. The approach has been applied on rules needed to regulate the communication between different railway organisations and other parties.
