Comparison of Signal Re-Design for G. Palya and Jakkur Junction by IRC and Webster’s Method
Keywords:IRC, Traffic Signal, Webster
Rapid growth of vehicles has resulted in traffic congestion at the intersection where there is absence of certain assets like traffic signals, timings, shortage of lanes etc. About 16 people die and 58 are injured every hour in India due to road accidents. The worst accident hotspots are near flyovers and junctions without signals. According to manual count with 15 minutes interval could be used to obtain the traffic volume data. The collected data is converted into PCU units. IRC and Webster’s method is a rational approach for signal design. The design is simple and is totally based on formulae’s laid down by IRC and Webster. In this method, the total cycle of the signal timing is determined which forms a total least delay occurring at signal. Traffic volume studies are to be made to determine the number, movement and classification of vehicles at the given location. The design of traffic signal is done according to Indian Road Congress and Webster’s method of signal design by adopting maximum passenger car unit (P.C.U) in the intersection of each direction. In present study traffic studies will be carried out at the “G.palya and Jakkur traffic signal” in order to re-design traffic signal timings according to present vehicular count and suitable precautions are to be given. After re-designing the signal timings by using IRC and Webster’s method, adopt highest total cycle length among two methods.
