Highways to Hell

This was a programme on Radio 4 on 4 Jan 2026, produced by Jonathan Brunert. Like every other BBC programme I’ve seen or heard about traffic congestion, it missed the point – that the main cause of congestion (and “accidents”!) is the system of priority and signal control. Instead it went on for half-an-hour about the easy target, roadworks. One thing they didn’t say is that roadworks are often minor – no more than a parked car in length – and don’t need those idiotic temporary traffic lights.
