Type of Tunnel

slope up to 3,5%

length profile

• river tunnel• slope: up to 3,5% uphill/downhill• length: 3.400m• kind of construction : caisson, boring, open construction• construction type of carriageway: depending on sections reinforced and non-reinforced concrete (iron)

Tunnel Operation

tunnel control centre

scheme of tubes and switching areas

ways of operating tunnelregular operating

• 4 tubes one-way traffic flowspecial operating : closure of tube(s) incase of accident or for service-purposes

• 2 tubes with one-way / 1 tube two-way traffic flow

• 2 tubes with one-way traffic flow• …

requirement: fast switching of tubes forchanging direction of traffic flow!

Requirements of Tunnel Operating

Automatic detection of all incidentswhatever their origin.

• fire• smoke

• accident in traffic flow• broken down vehicle• vehicle(s) standstill• wrong-way driving vehicle• abnormal slowly driving vehicle(s)

• shed loads on the carriageway• pedestrians on the carriageway

• heavily disturbed traffic condition:congestion, standstill, ...

• ...• ...

No overburdening of operating personnel!Incident Accident Desaster

Core Feature:Redetection of vehicles• continuously and reliably• under any impairment prevailing

in tunnels• for each tunnel-section

By that:Reliable measurement for eachtunnel section• current travel time• current number of vehicles• current kind of vehicles

Innovative Induction Loop Technology (MAVE®-tun)

Any type of incident / accident in tunnel is accompaniedby abnormalities in current traffic flow. They are reliableindicators!

Innovative loop technique measures current travel timeetc. continuously.

Multi-Purpose detector triggers alert when traffic flowbecomes abnormally.

Sound alarms operating personnel in tunnel controlstation.

Video image(s) of tunnel section(s) concerned isdisplayed on alarm screen(s).

Operating personnel visualize situation on alarmscreen(s) and initiate appropriate aid measuresimmediately.

Operating personnel tracks ongoing situation in tunneland supports rescue services.

Multi-Purpose Detector handles anykind of incident / accident in best way!

MAVE®-tun in Felbertauerntunnel Experiences and Results

Automatic alert ca. 5 minutes before emergency call from driver.Fire brigade arrived at fire only 3 minutes after emergency call.Tunnel reopened only 16 minutes after initial alert.

Presented AID-system MAVE®-tun for immediate automatic incident detectionand alerting installed and in operation in all 4 tubes of Elbtunnel A7 Hamburg.

Presented AID-system MAVE®-tun gains valuable rescue time: in relation tocurrent solution typically several minutes.

This facilitates substantially self rescue: vehicle occupants have more time toescape in case of incident.

This facilitates substantially rescue services: e.g. fire brigade can start firefighting in early stage, while fire is still controllable.

Tunnel operating personnel gets full information immediately in case of incident.

Practical experiences with MAVE®-tun in Elbtunnel A7 prove alerts to beextremely reliable with any kind of incident and within any kind of traffic situation.

Practical experiences with MAVE®-tun in Elbtunnel A7 prove no negativeinfluence by adverse environmental conditions on quality of alerts.
