Energy savings effectiveness of pretimed traffic control compared to actuated at signalized intersection

Fossil fuel consumption by vehicle is an issue of economical , environmental , and political concern .Reducing excessive energy consumption at isolated signalized intersection can reduce the dependency upon fossil fuels . guidelines are needed to help in the selection of the most energy efficient form of traffic signal control . A computer simulation program called NETSIM is used to develop guidelines for choosing the form of traffic signal control that minimizes fuel consumption. The results of 675 runs of the NETSIM simulation program are examined to determine the relationship between traffic volume levels and the most energy efficient form of traffic signal control. A prototypical four-leg intersection is selected as the test intersection. Simulation runs are made for both actuated and pretimed signal control strategies. For each run the NETSIM program’s traffic volume input is changed incrementally . The program is run and the predicted fuel consumption is noted. The resulting data are utilized to develop guidelines for selecting the most energy efficient traffic signal control.
