%X This paper presents the results of an investigation about a mobile low-cost dual-DGPS system for the fast tracing of the basic road design elements (horizontal plan, long section and cross sections). It is based on the use of GPS/GNSS technology and the requirements set by the ˇ°Safety Criterion IIIˇ± of vehicle movement dynamics introduced by the guidelines set by the Greek Ministry of Infrastructure, Transport and Networks. The main scope of the system is to become a useful and practical low-cost decision support tool for the inspection and the classification of road segments in safety categories based on a repeated procedure and the available vehicle fleet of the maintainer of the road. A major application task of the system could be the case of emergency conditions, i.e. to perform a quick survey of road deformation after a major disaster occurs, affecting the road infrastructure. The system consists of a moving vehicle equipped with GPS receivers. It was tested on a road segment that was accurately surveyed right after its construction (as-built) with classical surveying methods in order to verify its results. The performance of the system was evaluated on a mapping generalization base, more concerning the geometrical generalized road surface reliability and less the point mapping accuracy.
