Narrowing Lanes <br />Roadway Adjustments <br />Purpose <br />The reduction of the typical pavement width along a roadway. The narrowing can be achieved <br />physically by removing part of the pavement surface or by simply using pavement markings to <br />indicate narrow travel lanes. <br />Effects <br />Volumes <br />Little or no effect. <br />Speed <br />Possible reduction in speed. <br />Traffic Noise and Air <br />Little or no effect. <br />Traffic Safety <br />Potential for improved pedestrian safety due to shorter street crossing <br />times, but at the same time bicycle safety may be compromised by <br />physically removing part of the pavement surface. <br />Advantages <br />• Use of pavement markings to narrow street is relatively inexpensive ($0.20 <br />per lineal foot). <br />• Narrowing of streetmay provide opportunity for street beautification <br />programs. <br />Disadvantages <br />• May require the prohibition of on-street parking causing hardship or <br />inconvenience for residents. <br />• May result in shifting volumes to adjacent streets if number of lanes is <br />reduced <br />Problems Targeted <br />• Wide residential streets where speed reduction is desired. <br />• Excess street volume on multilane streets. <br />Design <br />• Must not create significant impact due to loss of parking. <br /> <br />
