Investigation of difference between network screening results based on multivariate and simple crash prediction models

Original language description

Identification of hazardous road locations (network screening) is the first step of road network safety management process. According to state-of-the-art knowledge it should be conducted using empirical Bayes technique which relies on a crash predictionmodel (safety performance function). However there is a dilemma in choice of a model: researchers strive for multivariate models, which demand area-wide databases of several variables; on the other hand practitioners require simple models, based only onfundamental variables, which are more easily available and able to be periodically updated. The research question was: ?What is the difference between network screening results based on multivariate and simple crash prediction models?? For the purpose ofinvestigation multivariate and simple crash prediction models were developed for regional road network of South Moravia (Czech Republic) and used in network screening. The results based on both models were compared and discussed ? the co
