The system which gives priority to buses at traffic lights
is being converted from inductive loop/transponder
technology to beacons progressively.

I wasn't aware such a system existed. When I rode the T4 from Feltham to,
er, T4, I noticed that no such system was in place, despite having been
promised in publicity. Where could I see concrete evidence of the system in
operation? (Not including the bus gate in Claygate, whose bollard and
traffic lights clearly are controlled by approaching buses.)


Converted sites usually have a beacon 50m upstream of the signals.
The beacon is mounted on a post of its own.

For inductive loop sites, there is no physical evidence.
