In 1993, the New York City Department of Transportation (DOT) received a federal grant (under the Intermodal Surface Transportation Efficiency Act of 1991, Congestion Mitigation and Air Quality) to research, design and test innovative traffic calming devices. This was part of a larger program to enhance the pedestrian environment in the city. Under this program, crash statistics analysis and policy codification were used to "sell" traffic calming within the DOT. This paper presents a crash analysis of Leading Pedestrian Intervals (LPI), a crash analysis of neckdowns, and the new neckdown policy. Neckdowns, also known as corner extensions, bulb-outs, and sidewalk expansions, narrow intersections by extending the curb at the corner.
