PAVEMENT MARKLNGS CHAPTER. This low cost use of painted lane markings is a very simple att~.mpt to change the pattern of driver behavior 'on any roadway, but par- ticularly on colle~tor or minor arterials. This concept utilizes the painted lane line to develop a parking reservoir and, in turn, creates the impression of a narrowed road- way, even ff parked vehicles are not present. It is generally used where the roadway width is greater th&n otc lane, parking is allowed, and no lane is present. Effects Volumes. It is very unlikely that any reduc- tion in volume would be realized because, in reality, the capacity is not reached. Speed. The impression of a reduced roadway width does appe~ to affect drivers in a man- ner that tends to slow them down. The reduc- tion may not be cDamatic, but it is a noticeable improvement. Traffic Noise, AJ_r Quality and Energy Con- sumption. As the level of speeding and potential hazardocs di-iving is reduced, an accompanying red.'uction in noise is possible. However, there should not be high expecta- tions for major reductions in noise levels. Air quality or energy consumption improve- ments are not expected.. Traffic Safety. The use of the painted line to delineate the parking area not only creates the impression of a nam-owed roadway reducing speed, but also d~courages vehicles from driving in or along the parking lane (especial- ly when parked vehicles are not present). This, in turn, reduces the frequency of at- tempts to pass on the right, use of the parking lane as a thru lane, and other hazardous action by irresponsible drivers. The net result is fewer lane conflicts, more defined driving patterns, and reduced potential for accidents of the pedestrian, passing on right, sideswipe, and parked vehicle variety. Community ReacHon. Generally speaking, the reactions have been very positive. This application is low cost, easy to do, involves no construction and does not have negative im- pacts on the adjacent property owners. Neighborhoods have indicated that driving patterns have improved and speeds are reduced. Only complaints (from drivers) have been that traffic moves slower thru the area. Additional Considerations The use of pavement markings may denote a major street. Case Study The City of Minneapolis has used this applica- tion on two collector roadways in residential areas (Portland Avenue South and Sunset Blvd.) with the result being a better charmel- ized vehicle flow and reduced speeds. There has not been adequate time to evaluate impact on accidents.' Improving the Re*ident[al Street Environment, May 1981~ F'"rlWA Neighborhood Traffic Control January 1994
