PERFORMANCE EVALUATION OF MODERN ROUNDABOUTS ON SOUTH GOLDEN ROAD

In 1998, Golden, Colorado, began renovations to the South Golden Road corridor. This paper gives a review of the selected corridor design, incorporating 4 modern roundabouts, and compares and contrasts it to an original partially-signalized configuration (2 signalized intersections; 2, 2-way stop-controlled) and to a theoretical signalized-improved configuration (3 coordinated signalized intersections; 1, 2-way stop-controlled). Empirical pre- and post-construction data was collected and compared to theoretical data generated with the calibrated Synchro/SimTraffic model of the signalized-improved configuration. The configuration with 4 modern roundabouts resulted in less delay per vehicle than the theoretical configuration. Travel times were 40-50 seconds less per vehicle with roundabouts compared to a signalized configuration. It is posited that this study represents an argument for examining a series of roundabouts as a feasible alternative under certain conditions.
