Cooperative vehicle test environment

Gothenburg is Scandinavia’s largest port and logistics hub. Every day, thousands of trucks arrive and depart the city to deliver and pick up trailers and containers. Ferry lines to Denmark, Germany and Norway provide connection points to other long distance road networks. A large share of truck drivers are foreign, not always familiar with the local traffic situation, environmental zone regulations, allowed / recommended truck routes and secure overnight parking.

The traffic across the local river (Göta älv) to access the port and ferry stops are bottle necks; there are 2 bridges and 1 tunnel, who’s limited capacity is a constant headache for commuters, transport companies and city traffic management.

Gothenburg is home to many refineries that supply petroleum products for the local Swedish market. This means that of dangerous goods transports are common in the area.

The urban transport environment in Gothenburg is characterised by an ambitious environmental policy which restricts heavy / polluting traffic in city centre areas. At the same time, the local merchants rely heavily on shopping tourists, and the need for efficient urban deliveries is obvious.

The Current approach of the Gothenburg traffic management office is co-located with the Swedish Road Administration regional office. Input data comes from loop detectors, travel time cameras and Floating Car Data (FCD). Dynamic information to drivers can be given via 13 Variable Message Signs (strategically placed to allow major re-routing options) and about 400 lane signals (Dynamic Speed Limits etc)

The present Cooperative test site has gradually been developed in close cooperation with the Swedish Road Administration (SRA) and AB Volvo for both CVIS and Safespot. The test site is operated by TSS with a backbone connected to both SRA and the public transportation company.

Test Site Assets

• Driving simulator
• CVIS test enivronment
• Safespot test environment
• ITS Simulator
• ITS Integration Lab
• ITS demo Theatre
• Databases for vehicle movement and driver monitoring
• Access to national road database
• Access to local traffic management system
• Access to local public transport traffic management (ITS4Mobility)

For the present CVIS and Safespot test site within Gothenburg the number of RSU are 8 corresponding with the need for the applications tested within these projects. Several of the RSUs are portable. The present locations of the RSUs are:

RSU 1:

The RSU is placed at the roof of the Pressbyrå kiosk at Lindholmens Allé, just outside our back office/integration laboraty.

RSU 2

Is mobile and can run on battery supply.

RSU 3

The RSU, Router and Host are placed in tunnel maintenance building. The antennas are placed at roof of the building. The distance between the Router and antennas is about 10m which required other cabling than the recommended. The range of 5.9 GHz seems not be affected by this longer cable.

The communication to Lindholmen Science Park back office is done with 3G.

RSU 4:

The RSU, Router and Host are placed in a cabinet mounted on the pillar for the bridge crossing the road entering the tunnel. The antennas are placed right above the cabinet on the same pillar. The pillars concrete and reinforcements lowers the range in some direction where the pillar is obscuring the sight.

The communication to Lindholmen Science Park back office is done with 3G.

RSU 5:

The RSU, Router and Host are placed in rest area building at Torrekulla. The antennas are placed at the roof of the building.

The communication to Lindholmen Science Park back office is done with 3G.

Antennas well above the roof

RSU 6:

The RSU, Router and Host are placed in rest area building at Klareberg. The antennas are placed at the roof of the building.

The communication to Lindholmen Science Park back office is done with 3G.
