Previa 3
Previa 3 is a software tool that allows to forecast the traffic situation to come (in terms of flow, occupancy rate and speed) based on historical data on traffic situations.
Previa 3 allows more control to Regional Offices of a Motorway Company by giving a common forecast method throughout the company.
The Motorway Concession Companies use Previa 3 to get more efficient explanatory factors of traffic events and to improve their forecast accuracy, in order to:
- Organize toll stations
- Schedule maintenance and renovation works
- Forecast revenues
- Help users to plan their trip
- …
Previa 3 technological highlights are:
- Traffic mid-term forecast
- Data consolidation
Previa 3 has been used since 15 years on 80% of the French toll motorway network and had been redesigned and re-engineered in 2017 at the request of all its users.
