“…If signals at intersections are 800 meters apart along a road then these signals should be coordinated [1]. Several studies in the literature have been found to focus on coordinated signal design [8][9][10][11][12]. However, no studies have been found to explore the scope of traffic signal coordination for intersections in Sylhet city.…”

Traffic delay is a very common phenomenon in urban intersections where the traffic volume on the approach roads is high. Coordinated traffic signals based on real-time traffic can be very useful for minimizing intersection traffic delays. Therefore, this study is aimed to investigate the prospect of a coordinated signal system for the busiest and most closely spaced intersections (Ambarkhana, Chowhatta, and Zindabazar) in the Sylhet city of Bangladesh. This signal system will allow a continuous flow of traffic through moving vehicles between successive coordinated intersections so that the vehicles that running at the design speed can pass through the coordinated intersections without a significant halt. An isolated signal is designed for three intersections and linked up to them based on offset values (time to travel from one intersection to another). Phase splits were adjusted using the Time-Space diagram.

“…Clough Harbour and Associates (2012) concluded that the improvements in the signal timing of the two coordinated corridors in the study area (Onondaga County New York, USA) were effective in improving traffic operation along the corridors. Pengdi et al (2012) demonstrated that the linear control (Green Wave) system reduced intersection delay and increased traffic capacity by improving the LOS at each intersection along the arterial road. Li et al (2013) pointed out that the optimization of the signal timing plan using the C++/CRL algorithm is efficient in improving traffic flow at oversaturated intersections.…”

Signalized intersections are critical elements of the highway system, thus improving the attitude of these intersections significantly influences the overall operating performance of the highways in respect of delay and level of service (LOS). Reduction in capacity and increase in delay at signalized intersections could be a reflection of poor signal timing as well as inadequate road geometry variables. A better comprehension of the reasons that affect signalized intersections performance can be useful in reducing delay and improving the LOS. This study aims toreview some of thepublished works on the evaluation of traffic operation at signalized intersections using both Highway Capacity Manual 2010 (HCM 2010) and several optimization software. Different approaches were used to identify the main input data (traffic volume data, geometric characteristics, and signal timing) required for the HCM and different optimization proposals including video recording technique and field survey. The outcomes of thepublished investigations indicated to improve the operational performance of these intersections including cycle length, adding lanes, creating overpass, prohibiting approach traffic from the intersection, and a combination of some proposals.The research also seeks to add tothis review the limitations of using different software suchas SYNCHRO, CORSIM, HCS, SIDRAand the considerable variability of delays and LOS using these software’s so that it may be updated for future experimental and simulation investigations on signalized intersections

“…The results can assist the usage of signal control and further educate traffic police during critical periods along with reducing travel time for each vehicle on the road network [10], [11]. Moreover, since Sathorn district can be considered as CBD in Bangkok, there are huge daily incoming flows every working-day morning.…”

Abstract. Traffic problems have become a plague of the society that cannot be abolished. This work considers the city of Bangkok and its urban road traffic problem, with a particular focus on traffic light control. Managing traffic control by generating optimal traffic signal timing is one of the solutions to reduce the delay at intersections. Synchro is used as a platform to achieve two things in this work. First, to initialize optimal cycle lengths of the intersections on Sathorn road. Second, to assist in the implementation of reversible lane that involves two traffic signal lights in short distance. All of the data are obtained by the technical team of Sathorn Model project, most of which are based on the field work. A comparative analysis is conducted between optimal cycle lengths and the actual signal timing as operated by traffic police from real data collection to see the improvement of travel times in various cases.
