Mixed Traffic Driver Behavioural Modelling at Urban Merge Section: An Experimental Study

The traffic conditions in developing nations of Asia are highly heterogeneous due to the presence of various vehicle types. The objectives of this paper are as follows. To study the road traffic capacity and delays at urban merging sections consisting of the mixed traffic stream. To analyse the interactions of vehicles both laterally and longitudinally by the inclusion of vehicle-type dependent factor. Using the data collected at a five-lane urban merging section using video recording method for the evaluation. To study the relation between macroscopic parameters (speed, flow, density, occupancy) and microscopic parameters (lateral clearance, average gap, space headway, lateral movement duration) is established by considering vehicle-type dependent factor. To analyse the effect of overtaking characteristics of different vehicle types at merge sections under mixed traffic conditions. The findings from this present research help in the operational analysis of merging locations on high-speed urban roads in Malaysia.
