The report presents the results of the evaluation of the five alternatives of the first-generation traffic control strategy for the computerized Urban Traffic Control System and Bus Priority System in Washington, D. C. The five control alternatives evaluated are: District 3-dial, time-of-day, traffic responsive, critical intersection control, and bus priority. They were evaluated to assess their relative impact on traffic during typical weekday morning, midday, and evening periods. UTCS/BPS surveillance data and moving car studies were used for evaluation. The computer-based traffic responsive alternative generally matched or exceeded the performance of the other traffic control alternatives. The over-all differences in delay between the various alternatives and the traffic responsive alternative were relatively small (2% degradation to 4% improvement). The critical intersection control alternative improved the performance of several intersections, particularly where offsets were poor. The bus priority alternative reduced bus delays by as much as 35% while increasing overall traffic delays less then 3%.
