Operational Improvements at Traffic Circles: Safety Analysis

The purpose of this study was to improve the safety and operation at three traffic circles in New Jersey. To do this, data were collected at the traffic circles to allow researchers to model the circles using the PARAMICS software simulation package. Once operational and safety factors were evaluated at the circles, alternatives for improvement were developed. The PARAMICS model was then utilized to evaluate the costs and benefits of each alternative. To augment the simulation work, empirical analysis was also performed using two model forms.
