Adaptive traffic signal control under demand uncertainty
2020This thesis investigates adaptive coordinated traffic signal control in the context of demand uncertainty. To address the uncertain nature of traffic demand, we first formulate the adaptive coordinated signal control problem into a two-stage stochastic program.

Adaptive green traffic signal controlling using vehicular communication
Frontiers of Information Technology & Electronic Engineering, 2017The importance of using adaptive traffic signal control for figuring out the unpredictable traffic congestion in today’s metropolitan life cannot be overemphasized. The vehicular ad hoc network (VANET), as an integral component of intelligent transportation systems (ITSs), is a new potent technology that has recently gained the attention of academics ...

Fuzzy adaptive traffic signal control-principles and results
Proceedings Joint 9th IFSA World Congress and 20th NAFIPS International Conference (Cat. No. 01TH8569), 2002Traffic engineering handles complex problems that include several objects, some of which are conflicting. Subjective and illogical behavior of traffic users still increase the vagueness of the transportation planning and study. Fuzzy logic and its capability to imitate human decision-making provide systematic approach to the multi-objective problem ...

Reinforcement learning for adaptive traffic signal control
2014Traffic signal control is very important to urban development. Most of the governments in developed countries continue to improve the safety as well as efficiency of their traffic signal control systems. In a well-designed traffic control system, fewer traffic accidents will occur. Moreover, the vehicle waiting times can also be shortened.

Data Fusion Techniques for Adaptive Traffic Signal Control
IFAC Proceedings Volumes, 2003Abstract Adaptive online traffic control in urban road networks requires information on the present and future traffic state. This information needs to be as complete and precise as possible. This paper introduces on the one hand a new method for online queue length determination based on data fusion technique (Mueck, 2002) and investigates on the ...

Adaptive signal control for urban traffic network gridlock
2016 UKACC 11th International Conference on Control (CONTROL), 2016With rapid urbanization all over the world, the traffic congestion problem is becoming increasing severe. In particular, many metropolitan areas suffer from the problem of network gridlock in peak hours, which is mainly attributed to the limited street space as well as inefficient intersection signal control to cope the excessive demand.

Adaptive Traffic Signals Control by Using Fuzzy Logic
Second International Conference on Innovative Computing, Informatio and Control (ICICIC 2007), 2007In order to improve efficiency of control strategy about traffic signal timing in single intersection, in this paper, a reckoning model about traffic signal control strategy is proposed. This model is built according to the number of delayed vehicles in one unit time, and an improved FLC (fuzzy logic controller) is designed, this controller's values of

Examining Perimeter Gating Control of Urban Traffic Networks with Locally Adaptive Traffic Signals
2016Traditionally, urban traffic is controlled by traffic lights. Recent findings of the Macroscopic or Network Fundamental Diagram (MFD or NFD) have led to the development of novel traffic control strategies that can be applied at a networkwide level. One pertinent example is perimeter flow control (also known as gating or metering), which limits the rate
