| Summary | Published in June 2003 IOT SERIAL No.92-60-5241，438 pp. IOT SERIAL No.92-61-5242，114pp. (System Operation Manual) The purpose of this study is to establish an information system to reflect the relationship between the cost of construction and maintenance on highway and the changes in LOS (Level of Service) of highway due to the improvement alternatives on highway. GIS is integrated into this system(i.e. ArcView) to adopt appropriate indicators for evaluation of highway performance and to build suitable database for analysis and future application of highway network cost and performance in the future. The study covers island-wide Taiwan, including freeways, expressways, provincial roads, county roads and collected the following data: Highway data：such as the administration area of agency, the mileage of highway, the width of highway and the number of lanes of highway. Highway network cost data：such as construction cost and maintenance cost of highway. The former is based on the data within the recent 5 years(1997-2001), the latter is mainly based on the data of 2000 and 2001. Level of service data：such as traffic volume, traveling speed, accident data. The core part of this study is to establish an information system of highway cost and performance. This system integrated the above-mentioned data, highway-related performance indicators, and all non-homogenous highway-related data with a GIS database, which is developed by the IOT and named as “2002 National Transportation Road Network Digital Atlas”. Finally, this system is used for practical tests based on the collected data. Besides, according to the analysis results of tests, the users could figure out where the abnormal situations of highway cost occurred and then provide necessary conclusions and comparisons of performance. The above comparisons can be conducted on different segments of the same road in the same year or different years, between different agencies, or different roads. In this study, ArcView 8.2 is used as the platform to establish the information system, which is integrated with Oracle to build the database. |
