English abstract:
The purpose of this paper is to evaluate if the accuracy of low cost GNSS (Global Navigation Satellite System) receivers is good enough to determine their position on the level of specific driving lanes. This could introduce a cost-efficient way to assess the impact of cooperative services.
A formal approach was used to compare different GNSS devices with respect to their lateral accuracy. This was done by directly comparing devices log files, which were recorded during the measurement run, with the position of a reference track recorded at the same time. Although the comparison was done in postprocessing, no additional inputs (e.g., improved orbits) were used.
The results showed that the lateral offsets of the tested devices were too big to guarantee the allocation to a specific driving lane. A theoretical smoothing process of the HTC Desire, which was the device with the smallest standard deviation, showed that if the manufacturer could increase the temporal resolution of the device from 1Hz to 50 Hz while keeping identical measurement quality, the lateral error could be decreased by 20%. This would result in a standard deviation of about 1.8 m. Considering such an improvement of the device and ideal GNSS coverage without shadowing, the driving lane could be determined.
