ANALYSIS OF POSSIBILITIES FOR THE USE OF VOLUME-DELAY FUNCTIONS IN THE PLANNING MODULE OF THE TRISTAR SYSTEM
PublicationTravel time is a measure commonly used for traffic flow modelling and traffic control. It also helps to evaluate the quality of traffic control systems in urban areas. Traffic control systems that use traffic models to predict changes and disruptions in vehicle flows have to use vehicle speed-prediction models. Travel time estimation studies the effects of traffic volumes on a street section at an average speed. The TRISTAR Integrated...

Driver Fatigue and Road Safety on Poland's National Roads
PublicationThis paper presents an overview of factors causing driver fatigue as described in the literature. Next, a traffic crash database for 2003–2007 is used to identify the causes, circumstances and consequences of accidents caused by driver fatigue on Poland’s national roads. The results of the study were used to build a model showing the relationship between the concentration of road accidents and casualties, and the time of day. Finally,...

MODEL OF MULTILEVEL STOCHASTIC ANALYSIS OF ROAD SAFETY ON REGIONAL LEVEL
PublicationIn this paper multilevel approach to the issue of road safety level on the road network of European regions, classified as NUTS 2 in statistical databases of the European Union, has been presented. Following the pattern of many publications on road safety it has been assumed that the risk calculated as the number of death casualties in road accidents per 100,000 inhabitants of a given region has Poisson distribution. Therefore,...

ROAD SAFETY MANAGEMENT TOOLS FOR COUNTRY STRATEGIC LEVEL
PublicationStrategic road safety programmes setting out long-term visions and road infrastructure development plans must be based on road safety forecasts and an understanding of the long-term impact of different measures on road safety. The objective of this paper is to discuss a concept of road safety management for an area of a selected country because there are no simple tools of road safety management for the development and implementation...

Analiza wpływu zmęczenia kierowców na ryzyko wypadków na drogach krajowych
PublicationPrzedstawiono charakterystykę czynników wpływających na zmęczenie kierowców. Zidentyfikowano przyczyny, okoliczności i konsekwencje wypadków spowodowanych zmęczeniem kierowców. Wykorzystując wyniki badań opracowano model objaśniający intensywność wypadków i ofiar wypadków w zależności od pory doby. Określono poziom względnego ryzyka wypadków w porze nocnej w stosunku do pory dziennej oraz mapę ryzyka wypadków z ofiarami śmiertelnymi...

The multivariate multilevel analisis of different regional factors impact on road saferty in european country regions = Wielopoziomowa analiza wieloczynnikowa wpływu różnych charakterystyk regionalnych na poziom bezpieczeństwo ruchu w regionach krajów europejskich
PublicationIn this research, the effect of the European regional differences on the risk of been killed in road accident in these regions is investigated. Factors which differentiate regions can be described as automotive, economic, infrastructural, demographic, geographic. Analyzed risk, counted as regional fatality rate was modeled by the Poisson model. Because of regional diversity of Poisson distribution parameters, the Poisson distribution...
