Abstract:

This paper presents the details of a terrain mapping system that has been used to measure median profiles. Details are presented of the system construction, design, and algorithms to process the data. The capability of the system is gauged by performing tests to compensate for vehicle orientation, tests for repeatability, and tests comparing the system with manual measurement. Results demonstrate the feasibility of using the system for median slope measurement. The advantages of using such a system as compared to traditional manual measurements are also demonstrated in practice as this system has been used to scan over 5000 miles of highways for measuring the slopes of divided rural medians. While the paper focuses on the median slope measurement, the paper can be viewed as providing a general direction for the design and testing of terrain mapping systems.
