Exult recently led the traffic safety analysis along 24 miles of I-64 in Hampton Roads, Virginia. This project consisted of adding general purpose and managed lanes along the corridor. Summary tables, charts and histograms were developed to identify any existing or historic crash patterns and safety concerns in the study area.
Crash rates and frequencies were calculated and compared to VDOT’s statewide and critical crash rates. Based on historical crash findings, crash modification factors were applied to predict crash rates and frequencies under future conditions to assist in determining any necessary roadway design modifications.
