A New Approach to Identifying Crash Hotspot Intersections (CHIs) Using Spatial Weights Matrices

A New Approach to Identifying Crash Hotspot Intersections (CHIs) Using Spatial Weights Matrices

In this paper we develop a new approach to directly detect crash hotspot intersections (CHIs) using two customized spatial weights matrices, which are the inverse network distance-band spatial weights matrix of intersections (INDSWMI) and the k-nearest distance-band spatial weights matrix between cr...
