INFORMATION NEEDS AND INNOVATIVE TOOLS FOR INFORMATION GENERATION AND PROVISION FOR ROAD ADMINISTRATION

Transportation is a crucial factor in the developing process, but the performance of the transportation sector is often sub-optimal, due to a lack of maintenance or demand-inadequate infrastructure provision. Transportation policy and the evaluation of policy alternatives aimed at improving this situation have to be based on up-to-date and reliable information about the transportation infrastructure and its usage integrated in transportation management and information systems. Generally speaking the tasks of transportation information systems may be defined broadly as: (1) infrastructure management including the planning, building and maintenance of infrastructure and the evaluation of policy alternatives; (2) managing the usage of infrastructure including models of transport demand and traffic counts, models for network planning and for the organization of network maintenance and (3) defining and controlling the legal and economic framework for infrastructure use. These tasks define the information needs of these management systems and have to be contrasted with the information situation, which often has to be characterized as one of low data availability, heterogeneous data and corresponding problems with data reliability and differing data requirements (e.g. details of infrastructure condition and seasonal influences). This paper discusses different methods for building reliable (GIS)-database and sketches a stepwise implementation process. Besides technical problems different data requirements and the organizational and institutional frameworks will be taken into account. The methods for the generation and updating of the database will increasingly rely on methods of remote sensing. This is due to the technological advances in this field, as well as the increasing availability of data and the methods of data processing. The necessary steps for creating and maintaining a reliable database can be found by complementing organizational measures, creating information as by-products of already implemented road administration procedures. Experiences from different developing and industrial nations will be compared in order to define best-practice models and avoid foreseeable problems. Existing information bases face the challenges of information provision and deployment as well as methods and questions of information access. Low investment costs, high reliability and ease-of information are shown to be crucial for information provision and usage. Systems and techniques for information access and information visualization/querying/analysis/reporting will be shown and evaluated in examples.
