Managing director of KEW Planning consultancy Kathryn Williams said: “I think they need to have the infrastructure in place.”
She said people may not like the “double-whammy” of being charged more for their SUV, when they already pay more in car tax.
“Is it going to be a deterrent? I think people will need to be extremely careful when they’re coming into the city,” she added.
“I think there’ll be concern from retailers and people with businesses in the city centre.
“I don’t think the communication around the consultation has been that successful, as somebody who works in the industry, we haven’t been notified.”
Ms Williams said public transport needs to be better.
She said: “I think we really need to look at improving things like our bus services, run a little bit longer, bit more frequent, same with the trains.
“I would use the train far more if they ran a bit later.”
She added there were “safety issues” with cycling in parts of the city.
