More of Bath city centre could be subject to a 20mph speed limit later this year.
Council chiefs want to bring in a blanket limit on non-A roads in the central part of the city as they progress a £500,000 programme aimed at cutting road injuries.
Many smaller streets in the centre - including Walcot Street - are already covered by a 20mph zone.
But Bath and North East Somerset Council wants to extend the regime to take in roads such as Great Pulteney Street, James Street West and North Parade Road.
The main roads around the edge of the city centre such as Upper Bristol Road, Lower Bristol Road and Pulteney Road would be excluded.
A council consultation exercise has now been launched, running until March 15, with a leaflet about to be distributed to homes in the area.
Cabinet member for transport Councillor Roger Symonds (Lib Dem, Combe Down) said: "Bath city centre is the busiest location for traffic in our area. The council is proposing to take action on making many of the streets safer for people on foot and who use bicycles. This will create a more pleasant, attractive environment for people to live, work, and visit. We hope people will have their say on our proposal.
"The statistics are on our side. The Royal Society for the Prevention of Accidents estimates that a pedestrian has a 90 per cent chance of surviving being hit by a car at 20mph, falling to a 50 per cent chance at 30mph and to ten per cent at 40 mph."
The council has already introduced new 20mph limits in Southdown and has been consulting about Larkhall and Peasedown St John.
The concept has been welcomed by police.
Chief Inspector Simon Ellis said: "Generally we welcome the concept of 20mph in built-up areas. Reducing the speed of motorists in built-up areas has to be a good thing and I have no doubt that it will make these areas safer places.
"I am hoping that drivers will take responsibility for the speed of their vehicles and adjust their driving habits accordingly. My officers will work alongside the council ensuring we raise awareness of the new speed limits and encouraging drivers to embrace and adhere to the new speed limits."
The council says no traffic calming will be installed in the city centre, and that new signs will be unobtrusive.
There is information about the timetable and proposed order for introducing the limits on the council's website on www.bathnes.gov.uk/20mphspeedlimit, or people can email transportation@bathnes.gov.uk or call 01225 394041.
