Traffic signals, even though crucial for safe operations of busy intersections, are one of the leading causes of travel delays in urban settings, as well as the reason why billions of gallons of fuel are burned each year by idling engines, releasing tons of unnecessary toxic pollutants to the atmosphere. Recent advances in cellular networks and dedicated short-range communications make Vehicle-to-Infrastructure (V2I) communications a reality, as individual cars and traffic signals can now be equipped with numerous communication and computing devices. In this thesis, an initial comprehensive literature search is carried out on topics related to traffic flow models, connected vehicles, eco-driving, traffic signal timing, and the application of connected vehicle technologies in improving the operation of signalized networks. Then a car-following model and an emission model are combined to simulate the behavior of vehicles at signalized intersections and calculate traffic delays in queues, vehicle emissions and fuel consumption. Next, a strategy to provide mobility and environment improvements in signalized networks is presented. In this strategy, the control variable is the advisory speed limit, which is designed to smooth vehicles' speed profiles taking advantage of Vehicle-to-Intersection communication. Finally, the performance of the control system is studied depending on market penetration rate and traffic conditions, as well as communication, positioning and network characteristics. In particular, savings of around 15% in user delays and around 8% in fuel consumption and CO2 emissions are demonstrated.

Millions of automobile accidents occur worldwide each year. Some of the most serious are rear-end crashes, side crashes within intersections, and crashes that occur when cars change lanes or drift into a lane. The holy grail of traffic safety is to avoid automobile accidents altogether. To that end, major automakers, governments, and universities are working on systems that allow vehicles to communicate with one another as well as the surrounding infrastructure (V2V/V2I for short). These systems show promise for such functions as intersection assist, left-turn assist, do-not-pass warning, advance warning of a vehicle braking ahead, forward-collision warning, and blind-spot/lane-change warning. This compendium explores the challenges in developing these systems and provides the latest developments in V2V/V2I technology. It begins with a series of overview news stories and articles from SAE’s magazines on the progress in this technology. This is followed by a series of technical papers on V2V/V2I dealing with the many technical aspects of design of these systems as well as discussions of such key issues as the need for extreme reliability assurances and traffic congestion overloads on the systems. Some of most interesting discussions in the book include: • Overview of a large-scale test in Germany to address reliability. • Effectiveness of different antennas and receivers that are used in various intersections settings, such as intersections where there are tall buildings or no buildings, and where high transmission power lines are located that can cause signal interference. • Various ways to communicate between vehicles and how messages are relayed to drivers. • Dedicated short range communication protocol for vehicle safety applications, which shows promise for combining and processing large amounts of information. Editor Ronald K. Jurgen prepared this book to be of use to engineers at automakers and electronic component suppliers; software engineers; computer systems analysts and architects; academics and researchers within the electronics, computing, and automotive industries; legislators, managers and other decision-makers in the government highway sector; traffic safety professionals; and insurance and legal practitioners. Mr. Jurgen served on the editorial staff of IEEE Spectrum for 30 years and is the editor of several electronics-related handbooks and several other electronics-related compendiums published by SAE International.

As a component of the intelligent transportation system (ITS) and one of the concrete applications of mobile ad hoc networks, vehicular networks are attracting an extensive attention from both academia and industry. The most important feature of these networks is their ability to extend the horizon of drivers and on-board devices and, thus, to make the time spent in vehicle enjoyable to both driver and passengers and improve road traffic safety and efficiency. Nevertheless, it is not usually casy to develop such systems due to the constraints related to the vehicular environment such as the road's architecture and the high mobility of nodes. These different properties offer two major challenges which are (i) offering sufficient QoS, and (ii) limiting the generated overhead. In this thesis, we focused on both vehicle to vehicle communication and vehicle to infrastructure communication. We tried to propose some optimized solutions that improve the quality of service in vehicular networks while generating a limited overhead and make easier the deployment of new services. First, we focused on the address configuration and mobility management in vehicular networks which are basic issues that act as pedestals to all other items. We proposed a multicast-communication-based solution to minimize the handover delays. Then, we bend over to study three major items in the vehicular network context : (i) data dissemination, where we proposed a local intersection-aware data dissemination protocol called ROD, (ii) data collection, where we proposed CGP protocol. This later is based on both cellular network and V2V communications, and (iii) self organization, where we proposed a self-organizing architecture based on geographic clustering. The performances of the different contributions were evaluated via simulations studies. Some of them were also evaluated analytically or/and via on-road real tests.
