<br />Chokers at Intersections <br /> <br />Roadway Adjustments <br /> <br /> <br />~ <br /> <br />~ <br /> <br />Purpose <br />Narrowing of the street at an intersection <br />to constrain the width of the traveled way. They <br />provide shorter pedestrian crossing distances <br />and provide protection to the beginning of a <br />parking lane. The driver also senses the roadway <br />narrowing when approaching one of these <br />measures, which can result in speed reduction <br />and a reminder that the driver is entering a <br />residential area. <br /> <br />-<.'!::'----- <br /> <br />a;E!I;1!l..:---- <br /> <br /> <br />1!;l <br /> <br />~ <br /> <br />Source: Institute of Transportation Engineers <br />Traffic Calming: State of Practice <br /> <br />Effects <br />Volumes Little or no effect <br />Speed Minimal changes <br />Traffic Noise and Air Little or no effect. <br />Traffic Safety Potential for improved pedestrian safety due to shorter street crossing times, but <br /> at the same time bicycle safety may be compromised by physicaily removing part <br /> of the pavement surface. <br />Advantages .
