“…The primary requirement was that the signal cycle time did not grow too large, since this may have had adverse effects on cyclists' safety and journey times. A companion paper by Middelham et al gives a report on the assessment of the SCOOT system's performance relative to the existing well-maintained and updated fixed-time system known as STAR (26). For both private and public motorized traffic, SCOOT gave an increased throughput of traffic, but journey time differences were inconclusive.…”

Since the 1950s, cycling has been a declining mode of travel in the United Kingdom. During this same period, sophisticated techniques for managing traffic in the urban environment have been developed. Given these circumstances, the presence of cyclists is often ignored by urban traffic control (UTC) systems, which are dominated by consideration of the flows and journey times of private motorized vehicles. Authorities are enthusiastic about the promotion of cycling as a mode of travel and are looking to see if this can be assisted by use of traffic management systems. The fact that cyclists and potential cyclists vary considerably in their abilities and performance, as well as in their attitudes to timesaving and safety, is highlighted. The context of the problem is set, the specific issue of detection of cycles is examined, the potential for implementation of priority measures in different types of UTC systems is discussed, and the issue is illustrated with some actual installations. Limited European evidence would suggest that only minimum effort is needed to take explicit account of cycling when a UTC system is being implemented. This supports the idea that cyclists can be given a higher degree of consideration within a UTC system without incurring significant additional costs. Only when cycling achieves a near-dominant proportion of the trips within a city and is growing in volume, as is the case in China, is explicit consideration to cyclists given.

“…In two papers for previous IEE Road Traffic Monitoring and Control Conferences, the implementation and first assessment of the SCOOT system in Nijmegen have been discussed by Middelham et al (1) and again Middelham et al (2). The implementation of the system was successful, bringing 40 intersections under SCOOT control, but took more time than expected due to the validation (tuning) process.…”

“…Both tasks (initial fine-tuning and calibration) are performed (if at all) by experienced personnel in the lack of an automated and systematic approach; thus there is no guarantee that the overall fine-tuning and/or maintenance procedure will end-up successfully. In some cases, the LSTCS has never achieved a satisfactory performance in the first place, as for instance in the reported case of the urban signal man-agement strategy SCOOT (the most popular urban signal management strategy worldwide) in the city of Nijmegen in The Netherlands [5], where the SCOOT application was abandoned completely in the end.…”

Abstract-In this paper, we study the problem of optimizing (fine-tuning) the design parameters of large-scale traffic control systems that are composed of distinct and mutually interacting modules. This problem usually requires a considerable amount of human effort and time to devote to the successful deployment and operation of traffic control systems due to the lack of an automated well-established systematic approach. We investigate the adaptive fine-tuning algorithm for determining the set of design parameters of two distinct mutually interacting modules of the traffic-responsive urban control (TUC) strategy, i.e., split and cycle, for the large-scale urban road network of the city of Chania, Greece. Simulation results are presented, demonstrating that the network performance in terms of the daily mean speed, which is attained by the proposed adaptive optimization methodology, is significantly better than the original TUC system in the case in which the aforementioned design parameters are manually fine-tuned to virtual perfection by the system operators.
