Adaptive Traffic Light Control With Quality-of-Service Provisioning for Connected and Automated Vehicles at Isolated Intersections

Toward Intelligent Traffic Light Control with Quality-of-Service Provisioning

Todays fixed-cycle traffic signaling is highly suboptimal and aggravates traffic congestion and waste of energy in urban areas. In addition, it offers no quality-of-service guarantee and makes travel time prediction extremely hard. While existing traffic light control research primarily focuses on improving the average wait time of cars, we study in this paper how traffic light scheduling affec...

Optimizing Signalized Intersections Performance under Conventional and Automated Vehicles Traffic

Automated vehicles, or AVs (i.e. those that have the ability to operate without a driver and can communicate with the infrastructure) may transform the transportation system. This study develops and simulates an algorithm that can optimize signal control simultaneously with the AV trajectories under undersaturated traffic flow of AV and conventional vehicles. This proposed Intelligent Intersect...

Automated Classification in Traffic Video at Intersections with Heavy

1 Pedestrians and cyclists are vulnerable road users and despite their limited presence in traffic events, these 2 two groups have the most collisions resulting in injuries and fatalities. Due to problems regarding data 3 collection for pedestrians and cyclists, there is a shortcoming in the field of road safety with regards to the 4 availability and quality of data for non-motorized modes. Als...

Optimal steady-state traffic control for isolated intersections

In this paper a simplified isolated controlled intersection is introduced. A discreteevent max-plus model is proposed to formulate the optimization problem for the switching sequences. The formulated max-plus problem is converted to be solved by linear programming (LP). In the special case when the criterion is a strictly increasing and linear function of the queue lengths, the steady-state con...
