The problem of traffic congestion in developing countries at alarming stage. The congestion in urban areas is in general at fixed locations and regular nature. Due to congestion we are losing man-hours, fuel, temper causing road rages and increasing health hazards due to air and noise pollution, VOC, wear and tear of roads and grading of Nation. The most of time problem is diverted by the all stockholders as “more number of vehicles, shortage of road facilities and user behavior”. The user behavior is developed with mobility atmosphere in years. The optimization of road capacity by reorientation and re-organizing of the existing facilities are an economical, environmentally beneficial, instantly effective, and to be implemented in very short time. For explanation and salutation of the problem, a very congested urban road “VIKAS MARG –Delhi-India” has been considered which is most representative of congested urban roads. The road is 44.00 m wide, divided 6 lane with footpath and service lanes. The capacity of the road is 2900 -4500 PCU and volume on the road is 4213 and 3400 PCU with minimum speed 10.63Km/H and 5.15Km/H in morning and evening pecks respectively. The un-optimized design of traffic signals, without any data is operated without synchronization also increasing congestion. The space for pick and drop for passengers and materials are not specified in roads and therefore the drivers of these vehicles unknowingly deciding themselves, waiting and parking within the lane. The road capacity can be increase up to 4500 to 5000 PCU by optimization.
