規劃建置全國車行橋梁統計系統

The Executive Yuan announced “Working Guidelines for Bridge Maintenance and Management” on July 21,2020. Point 9 in the guidelines regulates that “National statistical systems for vehicle bridges and for railway bridges should be established by the Ministry of Transportation and Communications (MOTC), and for pedestrian bridges should be established by the Ministry of Interior (MOI). The latter system should be interfacing to the former ones in order to provide national bridge information aggregated by the MOTC.” The no. 1098300073 official letter issued by the MOTC on November 10, 2020, ordered that establishment of the national statistical system for vehicle bridges and aggregation of national bridge information be performed by the Institute of Transportation (IOT).This project is aimed at developing the “National Statistical System for Vehicle Bridges” which includes a module aggregating national bridge information. The system was planned and structured based on the results of interviewing bridge experts and bridge management agencies. Five functional modules were established accordingly. These modules are (1) Statistical information for vehicle bridges, (2) Statistical information for national bridges, (3) Account management, (4) System bulletin, and (5) Data interface. The Statistical information for national bridges module has built-in tables to demonstrate statistics for vehicle, railway, and pedestrian bridges, such as “Status of bridge usage”, “Distribution of bridge ages”, and “Conditions of bridge inspection and maintenance”. In the system, vehicle bridge information is gathered from three bridge management systems currently operated by three MOTC divisions: IOT, Directorate General of Highways, and Freeway Bureau; while railway and pedestrian bridge information is obtained from the bridge management systems operated by the Taiwan Railways Administration, MOTC, and by the MOI, respectively. The “National Statistical System for Vehicle Bridges (including the national bridge information module)” has two login entrances. The entrance for users from government agencies needs valid permissions to use the five modules in the system. The entrance for the general public needs no account or password allowing the users to explore several typical statistical tables and their related basic bridge information in the module of Statistical information for national bridges.
