SPEED BEHAVIOUR IN RESIDENTIAL AREAS WITH DIFFERENT MAXIMUM SPEED REGULATIONS
GESCHWINDIGKEITSVERHALTEN IN WOHNGEBIETEN BEI UNTERSCHIEDLICHER REGELUNG DER ZULAESSIGEN HOECHSTGESCHWINDIGKEIT
Surveys of traffic flows, speeds and (in part) pedestrian movements have been carried out in 6 residential estates in Wiesbaden and Frankfurt, in order to establish the effects of maximum speed regulations (30 km/hr) and recommended speeds (20-40 km/hr) together with other measures. The surveys were made in the distributor roads having the highest flows in each area. (max Q = 60 ... 240 vehicles/hr). The following arrangements were tested: informatory signs (take care - residential area); maximum speed 30 km/hr at entrance to a residential area (on one or both sides); maximum speed 30 km/hr, repeated beyond every junction or crossing; maximum speed 30 km/hr with strong police supervision (in an estate inhabited by ameicans); recommended speed 20-40 km/hr. In all cases it was substantiated that, at most, a short-term reduction in speed took place. Checking after a few months showed that the speeds had reached their before-levels, i.e. that "neither informatory signs nor maximum speed limits nor recommended speeds caused drives to make any long-term reduction in their speeds". The authors therefore propose other measures - not tested in the surveys - such as visibility restrictions, changes in appearance of the street picture ("ntofree of development"), road marking changes (islands, artificial restrictions) and also planning and constructional means (limited length of roads, closing of junctions, tight radii, different carriageway surfaces) - all in order to ensure that the driver has the total impression of being in a residential road.
