IDA Road Tunnel
For projects specifically involving road tunnels, IDA Road Tunnel provides specialized, cost-efficient design and safety simulations, with features including:
- Improved traffic flow modeling
- Advanced structural analysis
- Seamless integration with external systems
- Comprehensive control toolbox and integrated 3D-editor
IDA Road Tunnel is the road tunnel subset of the complete IDA Tunnel. The program handles both longitudinally and transversally ventilated tunnels, with possible bi‐directional multi-lane traffic. A dynamic traffic model is available for realistic studies of congestion and traffic‐control scenarios.
The user enters a geometrical description of the tunnel, i.e. height coordinates and cross‐sectional areas along the length of each tunnel branch. Other input data cover ambient conditions (including portal wind pressure), traffic inflow, emission characteristics and coefficients of drag and friction. PIARC and similar emission tables are also included. Tables can be linearly combined and scaled with suitable age, weight and other factors.
Ventilation may be longitudinal or transversal, with airsupply and exhaust terminal devices distributed along thetunnel. For momentum jet fans the user specifies crosssectionalarea, efficiency and air velocity.
Three road traffic models are available: standing, moving and dynamic. The dynamic traffic model is able to predict many of the phenomena associated with real traffic such as congestion, multi‐lane traffic, vehicle and slope dependent maximum speeds.
