An optimisation method for a co-operative driving system at road junctions

What is it about?

An improved membrane-computing-based multi-vehicle optimisation method is proposed in this paper. The method is a potential solution to the multi-vehicle optimisation problem with constrained conditions and incommensurable objectives. It can better guarantee the safety of multiple moving vehicles at a junction than several traditional multi-objective optimisation methods. Experimental analyses show how the method can reduce delays at junctions, increase junction throughput and shorten overall journey times.

Why is it important?

The aim of this paper is to develop a novel method (namely, the improved membrane-computing multi-vehicle optimisation method (IMC-MVOM)) to optimise co-operative driving of multiple vehicles at traffic intersections. This proposed method is created on the basis of the detailed analysis of the multi-objective optimisation problems in the intersection co-operative driving systems. First, this research illustrates the intersection co-operative driving optimisation problem for a typical four-way intersection in a single lane. Then the multi- objective optimisation problem is formulated as a general intersection multi-objective constrained function. After multi-vehicle co-operative driving has been modelled as a structure of the multi-vehicle intersection co-operative driving system, the development and implementation of the proposed IMC-MVOM are discussed in detail as a potential solution to the above multi-objective optimisation problem.
