Title: RED-LIGHT AND SPEED PROJECT (PROROS). EVALUATION OF THE ENFORCEMENT ON SPEED AND RED-LIGHT VIOLATIONS IN AMSTERDAM, WITHIN THE PROROS (1993-1997) FRAMEWORK
Abstract: Between 1993 and 1997, the Traffic Department of the Amsterdam/Amstelland police has conducted an enforcement project on: (a) speeding on 61 roads; and (b) on red-light trespassing and speeding at four intersections. The SWOV Institute for Road Safety Research conducted an evaluation study on speed and accidents. There were three phases: phase 0 in summer 1993, phase 1 about six months there after, and phase 2 three months after phase 1. The effect on speed was strongest in phase 1: the average speed on 50 and 70 km/h roads was reduced by about 2.5 km/h. The percentage of speeders though was still high: 48% on 50 km/h and 40% for the 70 km/h roads. The accident evaluation compared the number of injury accidents and victims in the months September-December in 1991 and 1992 (before period) and 1993 (campaign period) on the roads that were enforced. A significant reduction of 25 to 36% was found. Four intersections and per intersection one direction was selected, again based on accident and speed history. Speed and red-light measurements were conducted in phase 0 in 1994 and phase 1 in 1997. The percentage of cars driving through red-light went down on the four intersections/directions. Speed was reduced on three intersections.
