A park name is not an address
Sophia Antipolis is not a town. It covers 2,400 hectares across five separate municipalities — Valbonne, Biot, Mougins, Vallauris and Antibes — and it is divided into named districts: Garbejaire, Saint-Philippe, Trois Moulins, Les Lucioles, Haut Sartoux. The figures published by the urban community give the scale: 2,500 companies, 38,000 jobs, 4,500 researchers and 5,000 students, on a site launched in July 1969.
The practical consequence is simple. A booking that only names the park names nothing. What works is the street and the number: route des Lucioles, route des Dolines, plus the building if you know it. That is the difference between a chauffeur waiting at the right door and a chauffeur circling a site the size of a small town.
The bottleneck has a name: the Weisweiller roundabout
The road linking the coast to the park runs along avenue Weisweiller. The town of Antibes publishes a figure of 50,000 vehicles a day on that roundabout. That is where the time goes, not on the motorway kilometres before it.
Local travel patterns explain the rest: more than two thirds of journeys are made by car, 22 % on foot, 6 % by public transport and 1 % by bike. An office estate that fills and empties by car, through a handful of access points, produces two very sharp peaks. A flight landing at 8 am is not the same job as a flight landing at 2 pm, and we plan it differently.
What the free busway does and does not solve
Line A runs on its own right of way from the Antibes interchange and it costs nothing. It solves the daily commute from the station. It does not solve an airport arrival, a door-to-door drop-off at a given building, or the luggage of a whole seminar.
For a business trip that chains two sites in one day, the question stops being a transfer and becomes hourly hire: the car stays with you, and the hourly rate is known before you leave.
