Living in Mars: on foot or by car?

Mars is a town where a car is needed day to day: few amenities are within walking distance. Worth anticipating if you plan to get around differently.

These figures are computed on the real street network (isochrone), not as the crow flies: they reflect journeys actually travelled.

Sources: Amenities: Permanent Equipment Database (BPE), INSEE. Road network: OpenStreetMap (© OpenStreetMap contributors, ODbL). Isochrones computed by NextToYourPlace.

Frequently asked questions

How is accessibility calculated?

By network isochrone: from the centre of the town we compute every street reachable in 5, 10 and 15 minutes on foot, by bike and by car, then count the amenities (BPE/INSEE) within. It is the real journey, not straight-line distance.

Which services are counted?

The six essential daily services: bakery, grocery, pharmacy, doctor, school and nursery.

Is accessibility in Mars good for a car-free family?

It depends on the number of services reachable on foot shown above: the higher it is, the more daily life works without a car. In rural areas this number is often low and a car remains necessary.

Is this data up to date?

Amenities come from INSEE’s Permanent Equipment Database (BPE) and the road network from OpenStreetMap. Calculations are refreshed periodically.
