纽约市交通局关于使用行人过路速度的政策旨在为行人提供足够的时间过马路，从而支持信号交叉口的行人安全。该政策遵循《2010 年公路容量手册》和《统一交通控制设施手册》中提供的现行指南，这些指南通常建议使用固定步行速度；然而，行人在人行横道上的行走速度根据行人密度而变化。随着人行横道变得更加拥挤，行人的行走速度变得更慢。因此，本文所述研究的目的是确定行人净空间隔期间动态行人步行速度的必要性并推荐指南，该指南根据行人在不同行人密度的人行横道上的行为而波动。这种控制有助于在密度特别高的人行横道上提供适当的行人间隙间隔。这项研究模拟了行人步行速度和密度之间的关系，以及在行人流量较大的信号交叉口（如纽约市中央商务区）的速度和行人流量比例之间的关系。根据分析的关系，速度和密度水平被确定为安全和拥堵水平的衡量标准。此外，研究表明，高密度人行横道内的行人过街速度受到相反行人流的影响。
The policy of the New York City Department of Transportation on the use of pedestrian crossing speeds is intended to provide sufficient time for pedestrians to cross the street and, thus, to support pedestrian safety at signalized intersections. This policy adheres to current guidelines provided in the Highway Capacity Manual 2010 and the Manual on Uniform Traffic Control Devices, which generally recommend the use of a fixed walking speed; however, pedestrian walking speeds at crosswalks vary depending on pedestrian density. As crosswalks become more crowded, pedestrian walking speeds become slower. The purpose of the study described in this paper, therefore, was to identify the need for and recommend a guideline for dynamic pedestrian walking speeds during pedestrian clearance intervals that fluctuated on the basis of how pedestrians behaved in crosswalks with various pedestrian densities. Such control could help provide appropriate pedestrian clearance intervals at crosswalks with distinctively high densities. This study modeled the relationships between pedestrian walking speeds and densities and between speeds and the proportions of pedestrian flows by direction at signalized intersections with heavy pedestrian volumes, as in central business district locations in New York City. On the basis of the relationships analyzed, speed and density levels were identified as measures of safety and congestion levels. Furthermore, the study showed that pedestrian crossing speeds within high-density crosswalks were affected by opposing pedestrian flows.
