Creating Frequency and Mileage Tables of RID Variables Using ARC/GIS
Track: Highways and Roads
Authors: Yusuf Mohamedshah
The Roadway Information Database (RID) is part of SHRP2 Safety Data administered and collected by TRB of NRC, an operating arm of National Academies of Sciences. RID contains roadway data collected from six sites by mobile van and existing data acquired from other sources. Documentation describing variables in RID has been developed but lacks frequency and mileage tables for all the variables. This paper describes Arc/GIS method to develop the tables of discreet and continuous variables.
