New York, like many US cities has recently seen gentrification in previously industrial dominated neighborhoods. As a result, urban streets in the affected neighborhoods must now accommodate a range of street uses, including walking, cycling, and commercial vehicle trips. Through mapping, spatial analysis, and development of collision frequency models in two case study areas located in the Brooklyn and Queens Boroughs of New York City, this project aims to identify the built environment factors that affect collision frequencies and to understand if gentrification has any significant effect on local street safety. Results of this project can inform policy and planning decisions for street design, land use decisions, traffic control, and curb management decisions.

与许多美国城市一样，纽约最近在以前以工业为主的社区出现了高档化。因此，受影响社区的城市街道现在必须适应一系列街道用途，包括步行、骑自行车和商用车出行。通过在位于纽约市布鲁克林区和皇后区的两个案例研究区绘制地图、空间分析和开发碰撞频率模型，该项目旨在确定影响碰撞频率的建筑环境因素，并了解高档化是否具有任何重要意义。对当地街道安全的影响。该项目的结果可以为街道设计、土地使用决策、交通控制和路缘管理决策的政策和规划决策提供信息。
