This paper examines the specific vehicle location needs of ITS system integrators, presents a set of field proven solutions and goes on to consider future needs. Environment, performance, functionality and economy are all considered along with emerging international standards. The need for ITS-specific products and solutions is identified. Increasingly, intelligent transport systems are required to deliver precise, reliable vehicle location data to drivers and to fleet managers in an easily digested form and with negligible latency. ITS users have been led to expect a level of performance that is extremely difficult to match in GPS-unfriendly urban environments and with rapidly increasing competition for communications bandwidth. At the same time, drivers are being expected to perform ever more complex tasks while driving. The solutions to these problems arise from a wholistic system-level approach rather than from an ad-hoc black box approach. The paper outlines an approach to ITS system design aimed at developing a range of ITS-specific vehicle location, communication and human interface products. It then focuses on the vehicle location elements, identifying specific requirements for ITS applications and the way that these can be met cost effectively. Elements considered include: (a) OEM GPS receiver; (b) In-vehicle AVL equipment; (c) In-vehicle navigation ergonomics; (d) DGPS solutions; (e) Dead-reckoning solutions; (f) GIS software; (g) Over-the-air protocols.
