| 摘要： | Maine's basic TINIS (Transportation Integrated Network Information System) brings together information data concerning accidents, road inventory, bridges, railroads, and project history/maintenance type information. Unlike other Highway Safety Information System (HSIS) states in which the linkage variable is some form of route-milepoint, the Maine system is a county/link-node system in which a six-digit code defines a specific node (e.g. an intersection, bridge, or other boundary) in a specific county. Each roadway section, or 'link,' is then defined by the node numbers at each end. The single raw file which will be received from Maine each year for use in the HSIS will include the following records: Accident Records (including information on general crash characteristics and on individual vehicles and occupants in the crash); Link Records (inventory information concerning roadway segments); Node Records (inventory information concerning junctions); Project History Records; Railroad Crossing Records; and Bridge Records. |
