Abstract

The availability of Global Navigation Satellite Systems

enables sophisticated vehicle guidance and

advisory systems such as Intelligent Speed Adaptation

(ISA) systems. In ISA systems, it is essential

to be able to position vehicles within a road

network. Because digital road networks as well

as GPS positioning are often inaccurate, a technique

known as map matching is needed that aims

to use this inaccurate data for determining a vehicle's

real road-network position. Then, knowing

this position, an ISA system can compare the vehicle's

speed with the speed limit in effect and react

appropriately.

This paper presents an on-line map matching algorithm

with an extensive number of weighting parameters

that allow better determination of a vehicle's

road network position. The algorithm uses

certainty value to express its belief in the correctness

of its results. The algorithm was designed and

implemented for use in the large scale ISA project

"Spar p°a farten." Using test data and data collected

from project participants, the algorithm's performance

is evaluated. It is shown that algorithm performs

correctly 95% of the time and is capable of

handling GPS/DR errors in a conservative manner.
