Integrated urban and interurban transport management with C-ITS

City overview
The metropolitan area of Lisbon has approx. 3 million inhabitants with 5 million person-trips each day. Recent data indicates that over 60,000 cars, 400 buses and 2,000 taxis circulate simultaneously during peak traffic periods. The metropolitan area of Lisbon has a large deployment of big network devices and C-ITS infrastructure in the main highways accessing Lisbon city (A1, A2, A5, A9, and A12). There are also traffic counters and classifiers, variable message, speed and lane control sign information to gather data from the transport network.

Priorities
⦁ Traffic optimization
⦁ Incident Management in transport
⦁ GHG emissions reduction

Actions
TANGENT aims to integrate data sources from multiple stakeholders, process and disseminate current and future statuses of the network, incidents, speed, route, and park & ride recommendations to users through different channels, including C-ITS infrastructure and variable message panels. The “Smart Network Balance Service” contributes to a better integration of urban and interurban traffic management in the Metropolitan area of Lisbon by:

⦁ optimizing interurban flows in highways by speed and route recommendations through C-ITS for connected vehicles
⦁ directing vehicles to unoccupied off-street and on-street parking places and adjusting prices to balance demand
⦁ improving synchronization of urban public transport with incoming inter-urban traffic flows from highways
