An Empirical Based Porous Flow Approach to Modelling Heterogeneous Traffic

The data required for the study was collected from YMCA road in Calicut city for frame based approach. Video-graphic technique was used for the data collection by the advantage over other data collection technique. For frame based approach video frames were taken approximately with a time lag of 3 s. From extracted data calculate the speed of vehicles, porous area, areal density, density and space headway of vehicles. From porous area data, pore space distribution function was determined by using easyfit5.5 software. The difficult was arises when extracting the traffic data from video frames. So for solving that problem on screen versus on ground distance graph was prepared. Best parameter to explaining the heterogeneous traffic system obtained as areal density rather than density measurement based on R-square value. The speed, areal-density model obtained was linearly decreasing relationship.
