The Road Safety Problem

During the working week, casualty rates peak at 8am and 10 am and 3pm and 7pm, with the afternoon peak being higher for both. Road casualty rates increase with the arrival of darker evenings and worsening weather conditions. Every autumn when the clocks go back and sunset occurs earlier in the day, road casualties rise. The effects are worse for the most vulnerable road users like children, the elderly, cyclists and motorcyclists.

Furthermore, according to the Department for Transport in 2018, pedestrian deaths fell slightly from 42 in September to 40 in October, rising to 56 in November, and 70 in December. This shows how as the evenings get darker, the risk of an RTC increases, especially for vulnerable road users..The casualty rate for all road users increased from 490 per billion vehicle miles in October to 523 per billion vehicle miles in November.

The relative peaks are explained by several factors: * Motorists are more tired after a day’s work and concentration levels are lower *Children tend to go straight to school in the morning but often digress on their way home, increasing their exposure to road dangers *Adults tend to go shopping or visit friends after work, increasing their journey times and exposure to road dangers *Social and leisure trips are generally made in the late afternoons and evenings.
