INVENTORY OF MEASUREMENTS TAKEN OF DRIVING PATTERNS AT INTERSECTIONS REGULATED BY TRAFFIC LIGHTS IN DENSELY POPULATED AREAS: FINAL REPORT

INVENTERING AV KOERFOERLOPP I SIGNALREGLERADE TAETORTSKORSNINGAR: SLUTRAPPORT

The introduction of RTI is expected to affect exhaust discharge by its influence on driving patterns. An inventory of measurements taken of driving patterns at intersections regulated by traffic lights in densely populated areas is presented. The aim of the inventory, which was limited to major intersections having speed limits of 50 km/h, was to study driving patterns there under present conditions. A large number of companies and other organizations were asked by letter or by phone whether they had conducted some form of measurements of driving patterns, and whether any results they had could be made available to the project. The results of three such investigations were seen as applicable. These comprised measurements involving a total of some 2300 cases of vehicles passing through intersections regulated by traffic lights. The results were analysed in terms of speed in approaching the intersection, lowest speed in passing through the intersection, frequency of stopping at the intersection, and duration of stopping. An analysis was made for each vehicle of how its speed was affected by passage through the intersection. The relative numbers of passages through the intersection that were disturbed, that were undisturbed and that involved stopping were determined for different types of intersections. Final conclusions are difficult to draw. Rather, the results might be viewed as representing case studies and the inventory as constituting a first step towards gaining a better understanding of the driving patterns of vehicles through intersections regulated by traffic lights in densely populated areas. Since the exhaust discharge that occurs is strongly influenced by driving patterns, continued investigation of driving patterns in such areas is needed. The findings and insights obtained in the project can be seen as providing a sound basis for further study.
