SAFETY OF ONE-WAY URBAN STREETS --ROAD USER BEHAVIOR. THEORY AND RESEARCH. PAPERS PRESENTED AT THE 2ND INTERNATIONAL CONFERENCE ON ROAD SAFETY HELD IN GRONINGEN, NETHERLANDS, AUGUST 1987

One-way streets are used as an inexpensive solution to capacity and parking problems, mainly on arterial or collector streets. In residential areas one way streets are used to prevent through traffic, to reduce conflicts at intersections, and to provide more parking space. The effects of converting streets to one-way systems have been summarized before. Generally, conversion from two to one-way results in an increase in speed and decrease in number of stops and total travel time. On the other hand, volume is increased and so is trip length. It is also clear that there are less potential vehicle conflicts on one-way intersections than on two-way systems. These effects, associated with one-way streets, have safety implications which may be reflected in the number, type and severity of road accidents. The decrease in conflicts and stops implies an increase in safety, while the increase in speed, volume and trip length may lead to an increase in accidents. Studies on the safety of one-way streets are generally of the before-and-after type and deal mostly with arterial or CBD streets. Most of the studies report a decrease in accidents of 20-30%. Midblock accidents are generally reduced more than intersection accidents. Some increase in accidents is reported for non-signalized intersections. As mentioned, most studies deal with conversion of CBD or arterial streets from two to one-way systems. The study pesented here, examines the safety of one-way streets by comparing accident rates on all one-way streets in one city to those on all two-way streets in the same city, for the same period.
