INJURY ACCIDENTS: A NECESSARY PRICE FOR ARTERIAL CAPACITY IMPROVEMENTS? SESSION 7

Broadway is a four lane urban arterial street located in Boulder, Colorado. In the summer of 1979, the traffic signals on a one mile section of Broadway, which passes along the edge of the University of Colorado campus, were changed from fixed time to actuated control. A computerized traffic signal system was also interconnected to the traffic signals. In addition, the traffic signals at one intersection were removed and replaced with stop signs on the side street and a raised barrier median was installed along the arterial. Handicap ramps were added in 1979 and 1980, and other minor geometric improvements were made in 1981 and 1982. The objective of all the improvements was to increase the carrying capacity of the street. The improvements were judged a success because the volume on the street has increased over thirty percent. However, the price of success was significant and involved a measureable increase in injury accidents. (Author)
