Özet

Analyses on traffic flow require accurate time-varying local traffic density information in order to effectively determine inflows to and outflows from freeway segments in several aspects of network traffic control. It is essential to specify the flow state, equivalently to derive density variable with the corresponding flow-rate measure, from primary traffic variables in order to provide accurate input to real-time traffic management strategies. In this paper, a study on the flow state specification process that employs feed forward back propagation neural network method to map sectional lane based density measure with raw traffic data collected from successive remote microwave sensor units mounted along a segment existing on the freeway network of Istanbul, is summarized. Classification of traffic flow states and matching the corresponding real-time flow state is obtained dynamically inputting raw flow measures simultaneously to neural density mapping and traffic flow modeling processes. The approach is promising in capturing instantaneous changes on flow states and may be utilized within intelligent management strategies such as incident control.
