A large part of CO2 emission comes from road transportation. The amount of CO2 emission from vehicles can be reduced by controlling traffic flows using traffic signals, because it is strongly affected by vehicular behavior. Although there are a number of traffic signal control systems to reduce travel time, such systems might not be effective to reduce vehicular emission because of the trade-off between...
We propose a distributed algorithm for controlling traffic signals. Our algorithm is adapted from backpressure routing, which has been mainly applied to communication and power networks. We formally prove that our algorithm ensures global optimality as it leads to maximum network throughput even though the controller is constructed and implemented in a completely distributed manner. Simulation results...
The paper develops a heuristic optimization algorithm for automated vehicles (equipped with cooperative adaptive cruise control CACC systems) at uncontrolled intersections using a game theory framework. The proposed system models the automated vehicles as reactive agents interacting and collaborating with the intersection controller (manager agent) to minimize the total delay. The system is evaluated...
For transportation tasks predominantly wheeled vehicles are used. This is due to a wheel's easy construction, its simple actuation and control implementation as well as the fact that no energy is wasted to overcome gravitational effects. But wheeled vehicles are best suited for a use on prepared terrain and surfaces. Their mobility on unstructured and rough terrain is significantly limited. These...
Network Zoning is a key problem for the coordination in hierarchical control system. In traffic control area, considering the characteristics of road network, like directed and spatial property, we give one appropriate method for network zoning. Inheriting the advantages of several community detection methods, this method takes the distance between intersections and the scale of intersection into...
