About Department for Transport’s (DfT’s) indicators
The department has adopted the following input and impact indicators, listed by coalition priority, as set out in our Business plan. Input indicators show the cost to the government of delivering certain products and services. Impact indicators show the performance or output of public services. These indicators aim to provide useful information to enable transport users and the wider public to make informed choices, and to make up their own minds about how the department and transport service operators are running.
