PAVEMENT MARKINGS CHAPTER. 6 This low cost use of painted lane markings is a very simple attempt to change the pattern of driver behavior on any roadway, but par- ticularly on collector 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 if parked vehicles are not present. It ~s generally used Where the roadway width is greater than one 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 appear to affect drivers in a man- ner that tends to slow them down. The reduc- tion may not be dramatic, but it is a noticeable improvement. Traffic Noise, Air Quality and Energy Con- sumption. As the level of speeding and potential hazardous driving is reduced, an accompanying reduction in noise is possible. However, there should not be high expecta- tions for major reductions in noise levels. Air quahty Or energy consumption improve- ments are not expected. · Traffic Safety. The use of the painted line to delineate the parking ~ea not only creates the impression of a narrowed roadway reducing speed, but also discourages 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 Reaction. 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 channel- ized vehicle flow and reduced speeds. There has not been adequate time to evaluate impact on accidents. Improving the Residential Street Environment, May 1981, FHWA Neighborhood Traffic Con2ol January 1994
