| dc.description.alternativeAbstract | Simulation has been an effective tool for evaluating various traffic signal control strategies. The main scope of this study is to develop a new simulation tool, named Korean hardware-in-the-loop simulation (HILS), which can overcome the limitations arising from the application of software-only simulation. In this study, the HILS system is systematically classified in terms of system configuration and usage. Under this condition, real-time detector information is generated automatically and transferred to signal control logic in order to verify the accuracy of detector information. This functionality of the system can extend the application areas not only for evaluating various signal control strategies but also for generating various new signal control tactics. The performance of system is tested in terms of an accuracy of detector information generated and delivered. For this process, the information generated from HILS emulator is directly compared with the information from a device on an equal basis. Evaluation is performed with two indices, equality coefficient and independent sample t-test using a SPSS (ver. 12.0). Test results indicate that the occupancy and non-occupancy detector information is very accurate with a 95% significance level both VISSIM and CORSIM model application. In addition, test results on signal phase duration have no significant difference. Two case evaluations are made to validate the feasibility of the HILS system developed. The first case study is to identify the effectiveness of on-site manual control for oversaturated arterial environment, and the second case study is to quantify the effect of exclusive bus signal control for exclusive bus lane operation in the City of Seoul. From on-site manual control test results, it is found that the manual control may generate negative effects on traffic flow in general. However, the input and output traffic volume into a link can be correctly controlled, then the manual control may provide better performance than a traditional signal control strategy for oversaturated arterial operation. In order to apply this manual control, it is recommended that an automation process should be developed because the manual control has no operational knowledge or guideline. The results also indicate that manual control should be limited to very special situations such as existence of unbalanced input and output volume, existence of spare capacity in downstream links, and a bottleneck location. From the second test results, it is found that the average travel time is reduced by 31% by providing an exclusive bus signal control without a negative effect on side streets. | - |
