Indian traffic is highly heterogeneous which consistof wide variety of vehicles in terms of static and dynamiccharacteristics. Due to heterogeneity of traffic, analysis oftraffic stream parameter become complex in nature.Collector road is a part of urban street hierarchy whosefunction is to collect traffic from local streets and distributethe traffic to arterial and sub-arterial streets or vice-versa.Collectors are designed to provide a greater balance betweenmobility and land access within residential, commercial, andindustrial areas. Hence proper planning for collector Streetis important for efficiency of network of the urban roadsystem. Hence the traffic characteristics are very importantin case of Collector Street. In view of this, attempt has beenmade to study traffic flow behaviour on macroscopic scaleby deriving relationship between speed (V), flow (Q) anddensity (K) for a selected stretch of collector street.Bhubaneswar the largest city of the Indian state of Orissa isselected for the study. Field traffic surveys were carried outon typical week day and traffic data was extracted. Theextracted data are analyzed in terms of vehicle composition,directional split, and space mean speed. Parameters likecapacity, optimal density, optimal speed and jam density arederived from the Q-K-V models. Results are compared withthe IRC prescribed capacities and also with the traditionalGreenshield’s model.
