INVESTIGATION OF TRAFFIC RESPONSIVE OPERATION

This research consisted of an investigation of the performance of the traffic responsive mode of control algorithm (TRSP). The purpose of the investigation was to determine how the various input parameters to the traffic responsive algorithm should be developed and to determine how sensitive certain of the parameters are with respect to proper selection of timing plans. The basic approach to the research was to use the 15-minute values of volume and occupancy that were generated during three, two-week periods of field observations. The data were collected during three, two-week periods of field observations. The data were collected during the summer of 1977. A series of computer programs were developed to determine which timing plan would have been selected if different values of KH and DELTA2 had been used. The report provides a brief description of the TRSP algorithm, a detailed analysis of the VPLUSKO values; an analysis of the KH factor; and an analysis of the potential of a DELTA2 factor, and an analysis of the sensitivity of the R(i,j) value.
