A computerized system has been developed to help improve road safety in Greece by suggesting maintenance priorities and countermeasures for specific safety hazards. The system uses accident data and expert judgments to create a priority list based on accident rates and types. It also includes a database to store information on accidents, road conditions, and maintenance history. By analyzing data before and after implementing safety measures, the system can evaluate its effectiveness and improve over time. This decision-support system aims to assist maintenance agencies in making informed decisions to enhance highway safety.
