A relationship between traffic flow variables and crash characteristics can greatly help the traffic engineer in the field to arrive at appropriate congestion mitigation measures that not only alleviate congestion and save time but also reduce the probability of crashes. Currently, no such decision support tool is readily available to traffic engineers who now mainly make vital decisions using their experience and intuition. This project investigated the feasibility of developing a methodology in which real-time data can be used to decide on diversion strategies that also consider crash risk. Models showing the interaction between flow and density (occupancy) and the relationship of these traffic flow parameters to crash characteristics were developed for specific sites in the Hampton Roads area of Virginia. These models were then used as the basis for developing a methodology that incorporates crash risk in identifying congestion strategies that consider crash risk.
