The following are maps of delays on roads in Cambridgeshire and the surrounding areas during the morning (07.30 to 09.30) and evening (16.00-18.00) peak periods. The maps show average delay during school term-time from September 2014 to August 2015.
Delay is measured in seconds per mile, which is defined as the difference between peak journey time and mean free-flow journey time (2200-0600).
Please note that there are a few anomalies, which are probably due to very short links
