| Abstract | The importance of the dispersion factor in the
coordination of traffic signa ls has led researchers in
Britain, the United States, and Canada to study the dispersion of vehicles as they progress along a street from a traffic signal. The present research describes an investigation to find how platoons o f vehicles released from a traffic signal disperse as they move along the street. Field surveys were carried out at four sites in
Metropolitan Bangkok. Parameters observed were the
successive two-second flows at the stopline, and at selected
points downstream from the stopline after the signal turned
green. From this information, flow-time diagrams were
constructed to describe the dispersion of platoons of
vehicles. These were compared with the flows predicted by
Robertson's and Pacey's models. It was concluded that the degree of platoon dispersion
at the study sites was significantly less than that
suggested by Robertson's parameters. There is evidence in
favour of Robertson's and Pacey's methods for the prediction of platoon dispersion. |
