The Métropole de Lyon, like all major European cities, faces major challenges in the mobility of goods and people. More than 4 million daily trips are made on its territory, of which 42% by private car which represents 2/3 of the kilometers traveled.

In order to improve the performance of buses in these constrained sites with high traffic pressure, the Lyon Métropole has experimented with a new device, based on dynamic management of the tracks. Innovation consists in moving from a spatial sharing to a temporal sharing of the road network .

This experiment took place in the first quarter of 2017, on Avenue Lacassagne in Lyon.

The principle of the dynamic bus route is simple: it is a question of allocating and temporarily dedicating a general traffic lane to the buses: the bus is then no longer stuck in the general circulation benefiting from a dedicated lane, while preserving acceptable traffic flow conditions outside the bus crossing.

The assignment of this dedicated channel is done in a "dynamic" way, by lighting of the LEDs on the ground and lighting panels of drawdown, indicating to the users the conduct to hold when a bus is approaching. Thus, as soon as the lane is dedicated to buses, the corridor is "sanctuarisé", and the cars are invited not to cross it

Dynamic bus corridor

Description :

The device breaks down in several times

Phase 1: When no bus is detected, the motorist is free to move and use both ways.
Phase 2: Upstream of the device, when a bus is approaching, it is detected then the first luminous panel tells users to fall back on the left lane. Simultaneously, the leds glow for strengthen vertical signage.
Phase 3: When the lane has been released by the motorists, the second dynamic panel lights up and indicates to the users the reserved character of the lane. It is transformed into a clean site and is accessible only to buses
Phase 4: When the bus crosses the junction, the light system of the first section goes out. Both lanes are again open to general traffic.
