An Optimal Dynamic Control Method for an Isolated Intersection Using Fuzzy Systems
Traffic flow systems are nonlinear and uncertain, so it is very difficult to find their optimal points. In traditional traffic control systems, the traffic lights of crossings change in a fixed time period that is not optimal. On the other hand, most proposed systems are sufficiently capable of coping with the uncertainties of traffic flow. To solve this problem, there is a need to develop expe...
متن کاملLow Emissions and Delay Optimization for an Isolated Signalized Intersection Based on Vehicular Trajectories
A traditional traffic signal control system is established based on vehicular delay, queue length, saturation and other indicators. However, due to the increasing severity of urban environmental pollution issues and the development of a resource-saving and environmentally friendly social philosophy, the development of low-carbon and energy-efficient urban transport is required. This paper first...
متن کاملDelay at Signalized Intersection
An intersection is a shared space that is used by more than one approach at a time. A signalized intersection is one where the shared space is used alternatively by a fixed number of approaches for a pre defined time interval as per the phasing scheme used for the intersection. Delay and queuing process are the main characteristics of such an intersection which help in analyzing and designing t...
متن کاملEvolutionary computation for discrete and continuous time optimal control problemsks
Nonlinear discrete time and continuous time optimal control problems with terminal constraints are solved using a new evolutionary approach which seeks the control history directly by evolutionary computation. Unlike methods that use the first order necessary conditions to determine the optimum, the main advantage of the present method is that it does not require the development of a Hamiltonia...
متن کاملAn Approximation to Discrete Optimal Feedback Controls
We study discrete solutions of nonlinear optimal control problems. By value functions , we construct difference equations to approximate the optimal control on each interval of " small " time. We aim to find a discrete optimal feedback control. An algorithm is proposed for computing the solution of the optimal control problem. 1. Introduction and statement of the problem. For nonlinear analytic...
