Title:

Assessing the Benefits of Installing V2I Communications on an Urban Orbital Motorway in a Medium Sized European City

Abstract:

As congestion continues to grow in urban areas, attempts to increase road capacity by means of road realignment, widening or removal of at-grade junctions can be very costly. After long periods of austerity in some European countries, funding for large scale infrastructure projects is still difficult to come by. This paper examines a potential cheaper alternative by assessing new technologies such as Vehicle to Infrastructure (V2I) communication. Recent research suggests that V2I can be used to alleviate congestion and improve safety without the need for large scale, disruptive road works which tend to have a negative environmental impact. The objective of the paper is to test the hypothesis that deployment of V2I communications technology on a three-lane busy orbital motorway (expressway) around a medium sized European city is economically viable. An audit of the M50 motorway around Dublin in Ireland was used to test the hypothesis. The possible benefits of the use of this technology in terms of reductions in both collisions and congestion were assessed. This was followed by calculation of the costs involved in the installation of the technology. The results of this work, a conservative assessment, show a benefit to cost ratio of 3.2 : 1 indicating that the use of V2I communications technology is economically viable and would deliver significant benefits.
