Traffic management methods for interurban - Urban interfaces

The vicinity of conurbations usually implies a strong interaction between, urban and interurban road and traffic systems. This results generally in extended congestion during peak periods and underlines the necessity of data exchange between urban and interurban traffic centres for the purpose of coordinated driver information and traffic control strategies. The paper proposes an integrated traffic management system, which will include several methods to assure adaptive traffic management in the covered area, such as: ramp-metering, driver information, variable message signs, variable speed.
