The focus of the present research is determining what users (i.e., truck drivers, route planners, dispatchers, logistics experts) of an intelligent route guidance system perceive as important information that should be made available and what information they perceive as acceptable to collect and/or monitor. This links well with the objectives of the HeavyRoute project. Extending the research reviewed above, road-user needs, vehicle operating costs and environmental costs will be able to be taken into full account as a result of using the HeavyRoute system. The same also applies to maintenance costs for road owners/managers arising from deterioration of roads and bridges and their impact on road safety. Working with all major stakeholders (with FEHRL and ERTICO as partners with unique links to road authorities, industry, and suppliers), the unique aspects of HeavyRoute will pave the way for the future large-scale development of a robust pan-European system. As part of the development process of the proposed HGV system, the user and stakeholder groups likely to benefit are identified and interviewed in order to assess their needs and desires. For example, infrastructure operators/owners are likely to require information about current and predicted traffic problems to support the decisions they need to make with respect to infrastructure operation and maintenance. As another example, the wider economic, environmental, and social issues that public authorities deal with must also be considered. The aim of this deliverable, therefore, is to identify the requirements for the proposed new HGV management and route guidance system, taking into consideration various key groups including: HGV drivers, who deliver goods on the basis of navigation and fleet management instructions; dispatchers or planners, who plan, monitor, and if necessary re-plan journeys; logistics companies, who are responsible for the transport of goods. These groups rely either directly or indirectly on information from: traffic information providers, who are responsible for collecting and processing traffic-related data within a given geographical area; traffic information centres, who provide end users with traffic information for further use (e.g., in an intelligent HGV management and route guidance system); traffic managers, who observe the current traffic situation and make decisions regarding the actions to be taken. This list is not exhaustive; other equally important groups include the general public, road authorities, all levels of government, map providers, weather-information providers, and infrastructure managers/owners. However, attention in this report focuses specifically on drivers and planners (and the logistics or transportations companies for whom they work), as the goal is to ascertain what information these users require in a HGV management and route guidance system; information that to a large degree comes from traffic information providers and centres, as well as traffic managers.
