EVALUATION OF NETWORK TRAFFIC PERFORMANCE MEASURES BY USE OF COMPUTER SIMULATION MODELS
The relation between traffic-signal-timing parameters and selected traffic performance measures of effectiveness (MOEs) was investigated by computer simulation of peak-hour flow conditions on an urban arterial in Madison, Wisconsin. The MOEs included delay, stops, fuel consumption, and exhaust emissions. A variety of signal-timing plans were generated by using time-space diagram methods and the TRANSYT signal-timing optimization model. Two computer simulation models, TRANSYT and NETSIM, were then used to develop traffic performance data for evaluation purposes. The results of the study showed that the signal-timing parameters that had the most significant effect on the MOEs were cycle length and the K-factor in the TRANSYT performance index. Speed of progression was highly correlated with number of stops: A higher value yielded a lower number of stops. Priority policy and split method did not show a significant impact on the MOEs. All MOEs can be improved when optimized timing plans are used instead of those developed by time-space diagram methods. In a comparison of the TRANSYT and NETSIM simulation models, the NETSIM model produced higher values for the MOEs under a given signal-timing plan. In a comparison of MOEs, number of stops and NOx showed a close correlation whereas delay appeared to be a strong surrogate for the other principal MOEs. (Author)
