MAP ACCURACY AND LOCATION EXPRESSION IN TRANSPORTATION--REALITY AND PROSPECTS
A suite of proposed location messaging standards was tested for the intelligent transportation systems (ITS) industry. Six databases were studied for the County of Santa Barbara (California), types and magnitudes of errors were documented, and the likely success of the proposed standards was examined. This paper synthesizes the test results and identifies caveats for the user community as well as challenges to academia. First, it was concluded that current messaging proposals are inadequate, and superior methods are required to convey both location and a measure of confidence to the recipient. Next, it was determined that there is a need to develop methods to correct map data geometrically so location is more accurately captured, stored, and communicated, particularly in mission critical applications. To address this, the authors developed methods for comparing maps and adjusting them in real time. Last, there must be standards for centerline map accuracy that reflect the data models and functions associated with transportation.
