Again private motorcars, buses and delivery vehicles are being targeted by imposed speed limits, road closures and diversions.

One of the claims being advanced for these proposals is a reduction in pollution by road vehicles.

Does this claim bear further scrutiny.

A delivery van currently has a target of a number of deliveries.

A reduction in its speed and imposed reroute decreases its available capability, ergo, more vans are needed.

Rerouting takes vehicles down lesser more congested roads, involves more road junctions more traffic lights, more stops and longer idling times.

These roads will require more repair leading to more road closures and therefore more road diversions.

Bus stops will impair access to properties in otherwise purely residential roads. All this for a claimed, unproven, reduction in air pollution.

Thank goodness we have out of town shopping.
