Some of London's traffic lights could be removed after a report showed the economy could benefit from such a move.
But chair of the GLA Transport Committee Caroline Pidgeon said the mayor's report "excludes any consideration of pedestrians or the economic bill that could arise from more pedestrian accidents".
"The very first priority for the mayor must be to end the scandal that across London over 400 pedestrian crossings at junctions fail to provide sufficient time for pedestrians to cross the road," she said.
