INTRODUCTION TO THE UTIS DATABASE FOR NEWCASTLE UPON TYNE

This paper proposes an open standard for defining transport networks. It first notes that there is currently no standardised format for networks; this is a major problem because conversion between formats for different transport models is tedious, time-consuming, and not easy to automate. It then describes the UTIS (Urban Transport Information System) standard database, which contains all necessary network objects and their attributes, and explains the structure of UTIS. UTIS aims to develop and maintain an urban multimodal standard transport network database for the central area of the English city of Newcastle-upon-Tyne, using the Smallwood SRP spatial database. Nine specific objectives of UTIS are stated. UTIS requires the inclusion of all network data, relevant to each network modelling tool used. Thus the network must be described at the 'lowest common denominator' level, i.e. decomposed so far that every feature, included in any of its models, is an object in its database. It is defined in terms of objects and attributes for a series of different levels. The paper also considers junction notation, data capture, external interfaces, an example for a junction using the VISSIM micro simulator, and results for a test site consisting of two roads meeting at a signal-controlled T junction.
