Traveling in Lewisham on a Friday between 5-6pm? You might want to use extra caution, as research completed by Whites Traffic Management revealed that this was statistically the most likely time for road traffic accidents across the borough.*
The most common month for collisions? June, a month known for increased activity around the borough due to better weather and longer daylight hours.
The figures, based on over 10 years of the Department for Transport’s road safety statistics**, indicate that drivers are more likely to experience collisions in Lewisham during the weekday, with the highest number of collisions occurring on a Friday.
In contrast, the least likely day across Lewisham for crashes is a Sunday, and fewest collisions happened between 4-5am, compared to the rest of the day.
The data also revealed that the peak time and day for road traffic accidents across all of London was also Friday, with October being the most collision-heavy month when taking all boroughs into account.***
Luke Dempson, Head of Communications at Whites Traffic Management, said:
“Transport for London data**** tells us that Londoners take almost 10 million car journeys daily, and it’s important for every one of those drivers to take care on the roads.
“Our research showed that the evening rush hour on a Friday is the most likely time for a collision to happen in Lewisham. The stress of commuting congestion and the fatigue towards the end of a working week may contribute to these numbers.
“Our passion at Whites Traffic Management is to help our clients ensure that every traffic management project is safe for drivers, pedestrians, and the traffic management operatives involved in directing the flow of traffic.
“These findings highlight just how important it is for traffic management plans across the borough to take the busiest periods on Lewisham’s roads into account.
