| Summary | This project employed probe car technology with global positioning system (GPS) surveying equipment to manually record travel time and travel speed data of all national highways (freeways), provincial highways (expressways included), county highways, and also the connectors of freeway/expressway interchanges which were completed before November 2010. The survey rounds were four for each highway (two-way included), and the survey time period was classified into three types based on traffic and highway characteristics of each highway, as follows: The weekday peak-hour period of metropolitan areas: The total number of survey rounds of each highway was four for the morning and afternoon peak-hour. The weekday off-peak period of suburban areas: The total number of survey rounds of each highway was four during the off-peak period. The holiday period of the scenic area highways and the intercity long-distance highways: The total number of survey rounds of each highway was four. In addition to the results of travel speed statistical analysis, the survey results were transformed into a GIS database, which could be used to perform the analysis of equal travel time contours, speed classification, shortest path, and travel time between any two nodes. Also, the database was used to update the link database of the Traffic Road Network Digital Atlas of the IOT. |
