PROJECT OVERVIEW

TPD evaluated traffic conditions at the entrance to a school and a park and developed recommended traffic mitigation measures including a mini roundabout. TPD provided development of construction plans for a mini-roundabout at the Rosedale Road/General Johnson Road intersection. Project included the preparation of construction plans, grade plans, lighting plans, and detour routes using NJDOT highways.

The project was necessitated by an accident where a pedestrian was struck by a car. The Municipality of Princeton and Mercer County agreed to improving safety at the intersection by the installation of a min-roundabout which, by nature of its design, creates lower travelling speeds of vehicles.

Additional crosswalks, lighting, and signage was installed to aid visibility of pedestrians. Additional flashing beacons and transverse rumble strips, along with pavement markings highlighting the existing school presence, were also added to help awareness of pedestrian activity.
