IF BORIS Johnson is pressing for countdown timers and other changes to traffic signals, as reported in the Gazette, he must ensure that no changes are made at the expense of pedestrians' convenience or safety.

There may be scope for changing the timing to reflect whether anyone is waiting to cross or not. But it would be totally unacceptable to have any reduction in the amount of time given to pedestrians crossing the road, or longer delays for people waiting to cross.

No one should have to dash across the road, and obviously there can be major difficulties for people who are less agile and those walking with children.

Priority should be given to the hundreds of junctions in London where traffic lights do not meet national guidelines for allowing pedestrians to cross safely.

Transport for London is still working on these improvements.
