Optimization

Abstract

Optimizing traffic control for a multiple-junction road network is a difficult but important task in traffic system design. A properly designed control strategy with various control measures is effective in handling traffic flows in diverse traffic conditions. Regarding the limits and low performance of existing control system, this paper presents a novel route information traffic control strategy (RICS), which integrates the route demands into traffic control strategy design. RICS aims to optimize network traffic performance and facilitate the movements on some specific routes with maximizing the capacity of infrastructure and maximizing the utility of certain route. It is potential to relieve movements blocked problem in saturated condition or improve the movements of big traffic demand route in some special traffic conditions. The measures of RICS are in a wide variety, which include adjustments in the signal timings and roadside geometric. They can be designed corresponding to the route demands in the network. RICS enjoyed big advantage in generating higher flexibility in signal control setting and adaptability to various traffic conditions. RICS potentially provides special control for preferential routes. The application system of RICS involves input system which provides traffic condition and route demands and output system such as traffic signal control and traffic management. RICS can be pre-designed or it can react or adapt to the real time traffic condition. This report presents a general concept of RICS including its design, application and evaluation. Finally, the case study of delft proves that the proposed RICS is promising and well-performed to improve the traffic performance of preferential routes.
