Abstract

This paper describes the implementation of urban integrated traffic control (UITC) in the Glasgow metropolitan area in Scotland. The sophisticated facilities now available within the Scottish National Network Control Centre are used to link urban traffic control (UTC), ramp metering, and route advice using variable message signs (VMS). The Glasgow UITC project is part of the TABASCO project of the European Union (EU), a European demonstration of multimodal and traffic control systems as a contribution to solving urban transport problems. This paper reviews the Glasgow UITC system, which uses the enhanced integration facilities offered by the Scottish NAtional Driver Information and Control System (NADICS). It describes the main characteristics of its control elements: slip road control, variable message signs (VMS), and IN-TUC (INtegrated - Traffic responsive Urban corridor Control) strategy. The evaluation of UITC includes a quantitative assessment of network impact, an assessment of network conflict, and a qualitative user reaction survey. The three time periods considered are: (1) existing (before); (2) after slip road control and before the TABASCO control algorithm (Phase I); and (3) after TABASCO (Phase II). The initial results of the UITC implementation are discussed.
