Variable Message Signs, real-time road information

Variable message signs have been implemented on most motorway networks of the SERTI area in order to provide real-time information about the traffic conditions ahead, events, weather conditions, travel time predictions and any on-trip information that could be useful to drivers. In most cases, these signs are located above the lanes and display short messages between 3 and 5 lines long.

Pictograms, break through the language barrier

Some of these signs display variable pictograms which indicate the traffic situation (accident, traffic-jam, rain etc.) by using clearly identifiable symbols. These pictograms are one of the most interesting solutions to providing traffic information to foreigners on motorways.


Travel time prediction


Travel time prediction is a key demand of drivers in order to manage their trip better and save time. Since the beginning of 2004, travel time has been available on about 1000 km of the SERTI network (motorway corridors in South-Western France, in Andorra, around Lyon, Barcelona, Valencia and Madrid). Soon the coverage will be extended (e.g.: South-East of France) and the first studies to provide travel time between two different countries will be carried out.
Moreover, SERTI is developing and improving calculation methods and simulation software, taking into account the level of traffic and the technology available.

Access VMS, read all about it before

The Access VMS are located upstream of a motorway in order to give drivers accurate information about the related network and to reinforce peri-urban and inter-urban continuity. This enables drivers to choose their way taking into account the real time traffic conditions.
