Road tunnels

IDA Tunnel handles air flows in road tunnels and related problem of pollution concentration due to emission from vehicles.

Results from simulations include air pressure and temperatures, flow rates and pollution concentrations along the tunnel. Input data are tunnel geometry, including flow friction factors and loss coefficients, plus traffic, emission data and air pressures at boundaries.

 

Mapping sections and platforms

 

IDA Tunnel can be used for realistic studies of phenomena associated with real traffic such as congestion, bi-directional multi-lane traffic, vehicle and slope dependent maximum.
