Abstract

The research aimed at a comparison of signal coordination with adaptive traffic control systems (ATCSs) and conventional traffic-actuated signal control systems in existing urban areas. ATCS performance was analysed on four selected urban arterials in Muenster and Remscheid. On these corridors a conventional traffic-actuated coordination was installed that could be switched over to ATCS. Data collection on all corridors was conducted to gather empirical data for the different signal control systems. The vehicle trajectories were analysed considering the number of stops and the delay. ATCS implementation in Muenster on the first corridor improved traffic flow significantly while on the second corridor diverse results were gained together with partly significant declines in the level of service with the ATCS. The traffic flow quality on the corridors in Remscheid could be partially improved by the implementation of ATCS, but declines were also identified. Adaptive traffic control systems Due to the impossibility to measure immissions locally, the environmental impacts had to be estimated using microscopic simulation. For one corridor in Muenster and one in Remscheid, the ATCS was integrated into the microsimulation program VISSIM. The simulated vehicle trajectories were analysed by the program PHEM to estimate the emissions. In Muenster, marginal improvements of 1.0% concerning the environmental impact were observed after ATCS implementation. In addition to the poor traffic-related effects in Remscheid, the ecological impact deteriorated as expected. The results of microscopic simulation in addition with an ATCS were afflicted with considerable erratic fluctuations implying that the results are only able to represent a tendency. As a result, ATCSs provide the possibility to improve traffic flow on urban arterial highways in addition to possible improvements of emissions and energy consumption. However, these effects usually cannot be taken for granted. In many cases a cost and time-intensive calibration-process is required. (Author/publisher)
