BBCThe latest 20mph zone to be introduced in Bradford is currently being assessed by the council to see how it is affecting drivers’ behaviour.
As well as the lower speed restriction covering Manningham and Heaton, speed humps and temporary road closures are in place to improve road safety.
Similar speed restrictions and traffic-calming measures are already in place in the city centre, Shipley, Ilkley and Barkerend.
The BBC asked residents and business owners what impact they have had in the latest areas to join the safety scheme.
Hamza Shakoor, who owns Shakoor & Sons Butchers on Emm Lane in Heaton, said he was “indifferent” about the scheme at first, “but it is a good thing”.
He said: “This is a long stretch of road, and it’s a main road, so cars normally come up flying at high speeds.
“It’s better because they have to slow down for the speed bumps.”
Mr Shakoor praised the installation of a pedestrian crossing with push-button traffic lights near a local school.
But he criticised the use of concrete planters to temporarily block off one entry lane to North Park Road as it caused “more congestion” on the main Emm Lane.
Lisa Robertshaw, who runs the nearby Village Bakery, was sceptical of the impact of the new measures.
She said: “I don’t think it’s particularly made any difference at all.
“I mean if you see the cars speeding up and down here, if you watch them… none of them do it (20mph).”
She said she was in favour of the new limit but wanted more enforcement.
Ms Robersthaw said the speed restriction signs were too small and many drivers were unaware of the new limit.
Stephen Todd, caretaker at St Bede’s and St Joseph’s Catholic College, has lived in the area all his life.
He said: “I would say a bigger issue, for example, is the parking zones that they have.
“Maybe not so much outside shops, but elsewhere where there are no shops and they’re parking so it narrows the road which does make it more dangerous.”
He said he did not see the need to reduce the old 30mph speed limit.
Lucia Kalhousova and her son Samuel Kalhous live on a street that has temporary concrete planters placed at one end.
Samuel said: “We feel it is blocking the road for families like us living on the street.
“Every time we go to school, which is nearby, we have to take a diversion onto the main road to get there.
“I think it’s alright if the speed limit is reduced. I think there should be speed bumps but I don’t think there should be blocked-off roads.”
Alex Ross-Shaw, executive member for regeneration, planning and transport at Bradford Council, said: “We’re committed to making our neighbourhoods safer, healthier and more accessible for everyone.
“The new 20mph zone in Manningham is a key part of that vision and has been shaped by local input throughout.”
He thanked everyone who took part in the council’s consultation and those who “supported the scheme”.
The findings of the review will be presented to councillors at a later date.
