ABSTRACT

Matching mobile phone signaling switching data with road and extraction of road travel speed is the foundation of obtaining traffic information by using mobile phone signaling data, however, the existing matching method extracting a feature sequence has a large error, and results in a lot of waste of road test mobile phone signaling switching data. Using the location feature of mobile signaling switching place, put forward an urban road calibration and matching method based on the longest common subsequence dynamic planning. By pre-processing of mobile phone signaling data measured on the road, calculate the correlation threshold of urban road calibration sequence based on the longest common subsequence; by dynamic programming method, calculate the degree of association of the sequence that has not been matched and the road test sequence set and compare it with correlation threshold, and match cellular signaling data with urban road, then calculate the travel speed of the successful matched sequence. The result of example analysis shows that the result of the road matching and travel speed calculation is less error.
