People living near two roads named "the worst rat run in London" by a transport campaign group are calling for safety to be improved. They say problems began when traffic lights were installed in neighbouring Alexandra Park Road, in Muswell Hill.
Motorists now use The Avenue and Dukes Avenue in north London to avoid them.
Haringey Council says it is looking at how to tackle the volume of traffic on the roads - also named by Transport 2000 as the UK's second worst rat run.
As well as a poster campaign, residents have strung up a huge banner across the street voicing their concerns.
Councillor Ray Dodds said: "Although we are aware of the concerns of some residents there are sadly other roads within the borough which are of a higher risk and which have to be tackled first.
"However, we have been working for several months to find ways of preventing rat runs in this area.
"The council is seeking residents views and consulting with community and residents' associations on options to do this."
