Improving road safety is a public interest target both at French and European level. Also, both are convinced that speed limits must be better observed in order to reach the European Commission's ambitious target for 2010, which is to cut the number of fatal and serious casualties by 50% on theUnion's roads. Apart from repression, technical progress can help to reach this goal. Today, intelligent speed adapters (ISA|) can be put on the market, but they lack data to operate. All professionals agree that supplying these systems with reliable data is vital to their efficiency. The French BALI project was launched to prove the feasibility and interest of a speed limit data collection and delivery device on the scale of a French testdistrict: Yvelines. This means creating a technical data collection infrastructure, but above all including data holders, with local authorities atthe forefront. At the same time, French motorway concession companies started experimenting to collect and broadcast speed limits on their networks, not only permanent, but also temporary (road works) and dynamic (trafficcontrol) speed limits. This approach is fully complementary with the latter. For the covering abstract see ITRD E139491.
