SafeLight: A Reinforcement Learning Method toward Collision-Free Traffic Signal Control
نویسندگان
چکیده
Traffic signal control is safety-critical for our daily life. Roughly one-quarter of road accidents in the U.S. happen at intersections due to problematic timing, urging development safety-oriented intersection control. However, existing studies on adaptive traffic using reinforcement learning technologies have focused mainly minimizing delay but neglecting potential exposure unsafe conditions. We, first time, incorporate safety standards as enforcement ensure methods, aiming toward operating with zero collisions. We proposed a safety-enhanced residual method (SafeLight) and employed multiple optimization techniques, such multi-objective loss function reward shaping better knowledge integration. Extensive experiments are conducted both synthetic real-world benchmark datasets. Results show that can significantly reduce collisions while increasing mobility.

Reinforcement Learning For Adaptive Traffic Signal Control
By 2050, two-thirds of the world’s 9.6 billion people will live in urban areas [2]. In many cities, opportunities to expand urban road networks are limited, so existing roads will need to more efficiently accommodate higher volumes of traffic. Consequently, there is a pressing need for technologically viable, low-cost solutions that can work with existing infrastructure to help alleviate increa...

متن کاملReal-time Reinforcement Learning in Traffic Signal System
Real-time optimization of a traffic signal system is a difficult decision-making problem with no considerable model given. To achieve this optimization, a perfect tradeoff should be made between the distributed learning in each individual intersection, and the integrated cooperation in the whole traffic grid. This paper explores such a tradeoff and designs an efficient traffic signal system by ...
