The general objectives of this project are to:
- define recommendations concerning the use and the improvement of existing equipment used for the data acquisition subsystem. Propose additional equipment if required,
- define recommendations concerning the use and the improvement of existing traffic control schemes. Propose additional traffic control models and schemes to ensure safe and high volume traffic,
- review existing radio communication systems in underground environments and define recommendations for a standardized system taking into account the continuity of radio broadcast, the continuity of security service communications and their integration within an IRTE,
- explore variable traffic message signs using electromagnetic, LCD & LED technologies and make recommendations as to their design (taking into account operational considerations such as impact on the driver, visibility, easy of use, flexibility and maintenance costs),
- review existing systems with respect to access control,
- recommend a standardized system architecture all of the above.
Traffic congestion and safety in road tunnels are frequent problems for the people in charge of a traffic network. The objectives will be to provide recommendations for a tunnel management system interfaced to an integrated road transport environment (IRTE). The approach will be practical and will make use of data and expertise related to several tunnels in different countries in Europe. The main objectives will be reached by covering the following aspects: existing traffic control schemes, radio communication systems in underground environments, traffic equipment, taking account of new technologies, the operation of ventilation systems, the operation of lighting systems, response to incidents and reduction in the number of tunnel operating personnel.
The TUNICS project has issued recommendations for an integrated tunnel management system including specific recommendations for traffic management, technical management, toll collection, telecontrol network, radio communications, traffic data acquisition, sensors and variable message signs.
A major emphasis of the program will be pilot projects, to demonstrate that the proposed recommendations will actually improve efficient safety in tunnels.
A prototype was made available on 01/09/92
The aim of the research was to investigate the feasibility of integrating road tunnel management systems into the integrated road transport environment (IRTE). The importance of this interfacing and the potential benefits arising from it are discussed.
Tunnel functional subsystems were received and the following aspects of interfacing them with the IRTE were examined:
vehicle location systems;
dynamic route guidance;
driver information systems;
the radio data system traffic management channel;
motorway traffic flow control and monitoring;
incident and congestion detection;
road condition and weather monitoring;
Guidelines for a pilot project were provided.
The approach will be practical and will make use of data and expertise related to several tunnels in different countries in Europe.
