"The suspicion is that Park Road off the A4 may be used as a way of avoiding the Sutton Court Road junction and also I think it is an unguarded entry point to the ULEZ. There certainly seems to be more traffic than there ever used to be coming south."fyi in the September 2019 traffic survey, there was on average about 1100 vehicles on weekdays using Park Rd between the A4 and Chesterfield Rd with the split being about 800 southbound and 300 northbound.In September 2020 (before the barrier was implemented), there was about 700 vehicles per day, about 400 southbound and 300 northbound.In May 2021 (after the barrier was implemented), there was about 550 vehicles per day, with about 250 southbound and still about 300 northbound.If anyone was desperate to know, I could check from the September 2019 survey how much of the northbound and southbound traffic started or finished their journey within the Grove Park area or drove straight through.I am sure there will be more surveys to measure the effectiveness of the current arrangements.
