TUNNEL MANAGEMENT SYSTEM CARMEL TUNNELS, Haifa, Israel

, 2009/2010

Challenge

The old part of Haifa with port and major business districts are located on a narrow coastal strip beneath 550m high Mount Carmel. To relieve traffic-congested downtown Haifa and to provide an alternative to driving up and across Mount Carmel the Carmel Tunnels Project was started.

The project consists of two sets of twin tunnels, the 3.5 km long western set and the 1.6 km long eastern set, with two lanes of traffic in each tunnel and four portals.

Details

The entire project is 6.5 km long and includes 5 conventional bridges, 6 segmental bridges and 11 kilometers of roads.

 

 

Using the tunnels, which require paying a toll, cuts the current travel time from the Haifa South interchange in the west to the Checkpost interchange in the east from 30 - 50 minutes down to 6 minutes. Driving all the way through the tunnels will cost 11.40 Shekels (approx. 2.35 €).

System description

The central software allows controlling all tunnel systems by means of a visualization screen. All information is available all the time in one overview. The tunnels are monitored from the tunnel control center in Krayot.

The system is connected with the facility management system (FMS) including fire detection, electrical control, light control and ventilation control. In case of an alarm e.g. fire alarm it reacts with predefined measures such as tunnel closure.
