HIGHWAY EMPIRICAL TRAFFIC FLOW PATTERNS AND REGRESSION ANALYSIS
The aim of this paper is to analyze highway empirical traffic flow patterns including regression analysis at the highway tollgate station Josanica at the north exit of the capital of Bosnia and Herzegovina Sarajevo. The traffic flow analysis in this paper includes determination of arrival and service time pattern distributions and development of traffic flow time series regression forecasting models of the traffic flow. Data for this research are retrieved from the highway software system. Research shows that it is possible to build reliable regression forecasting models to predict number of vehicles per month, per week and per day in certain week as well as per defined time periods during a day. Time needed to pay at the toll station (service time) is measured by observation. This study presents arrival pattern distribution and service time distribution. Results obtained by this research will be used for the simulation of waiting line models and improvement of the existing system as well as for the highway service facilities demand forecasting.
