COMPASS4D is a European project aiming to increase drivers’ safety and comfort by reducing the severity of road accidents as well as avoiding queues and traffic jams. Seven European cities (Bordeaux, Copenhagen, Helmond, Newcastle, Thessaloniki, Verona and Vigo) have joined forces with the shared objective of substantially improving road safety, increasing energy efficiency and reducing level of congestions for road transport by implementing Cooperative ITS.
Challenges addressed

Results/Lessons Learnt

Road safety, energy efficiency and reduced levels of congestion in road transport need substantial improvements. Cooperative solutions have significant potential for addressing these issues and Compass4D aims to prove the benefits of these services to key stakeholders. Consortium partners plan to cooperate closely with their US and Japanese associates, contributing to global harmonisation of these services. The target users of Compass4D are drivers of Buses, Emergency Vehicles, Trucks, Taxis, Electric Vehicles and Private Cars. They all need information to make their driving safer, less stressful and more energy efficient, for example, bus drivers will get support to better keep their time schedules. Emergency vehicles can accelerate their emergency interventions in a safe manner. Drivers of electric vehicles will benefit from extended driving range and confidence. Truck, taxi and bus drivers will be more relaxed when travelling through equipped intersections. The two safety-related Compass4D services, Road Hazard Warning (RHW) and Red Light Warning (RLW), will support the driver by providing (audio and/or visual) in-vehicle notifications when the driver approaches a dangerous situation, e.g. traffic queues in a dangerous location, or if the driver risks running a red light. The Energy Efficiency services will provide recommended speeds to drivers of all vehicles when approaching an intersection, depending on local policies. It will also give priority at intersections for given vehicle types, e.g. emergency vehicles or delayed buses. A combination of mature technologies developed in earlier R&D projects and readily available (pre-) commercial equipment will be used. Dedicated Short Range Communication (i.e. ETSI G5) and cellular networks (i.e. 3G/LTE) will be used, following ETSI TC ITS standards. Compass4D services rely to a large extent on real-time information provided by the infrastructure. This information is generated locally at the roadside equipment or centrally by the operator (public road authorities or cities) which are playing a central role in the project. Based on proven benefits from the pilot phase, the cities/public road authorities participating in the project will maintain and further develop the infrastructure. The in-vehicle units shall be maintained by the equipment suppliers, and paid for by the end users.
