This Overseas Road Note provides detailed guidance on the design and operation of computer-based road management systems. The note draws on material from a number of sources and combines experience of active involvement in many institutions with on-going research carried out by TRL Ltd on this subject. The fundamental message of the Note is that institutional management issues in a road administration must be addressed first before a technical improvement, such as introduction of a road management system, can be a success. The structure of the Note reflects this, with its division into three distinct parts: Part A is meant for senior policy and decision-makers. It outlines the principles of best practice in road management and the role that computer-based systems might play in supporting management procedures. Part B is intended for use by professional staff who have the task of recommending the type of system design to be adopted. It addresses the process involved in design and identifies a generic approach to system specification. Part C, which is intended for staff involved in system implementation, deals with the training activities needed to ensure the successful introduction of a computer-based system and its continuing operation, and also addresses issues related to the day-to-day management of systems.
