The New Jersey Department of Transportation (NJDOT), in partnership with the Delaware Valley Regional Planning Commission (DVRPC) and Burlington County officials, used predictive safety analysis tools to help secure funding for a modern roundabout at a rural intersection. The intersection of county road 528 and county road 660 in Chesterfield Township had experienced severe crashes and had been identified for improvement in a prior study conducted by the DVRPC. However, state or county construction funding was not available. The team decided to apply for Highway Safety Improvement Program (HSIP) funding. However, HSIP requires a thorough safety analysis of projects before funding approval to ensure the chosen design provides the best benefit/cost ratio.
The analytical effort was recognized by the Federal Highway Administration in both a case study with links to several useful resources and the below video.
