§ Sir W. Brassasked the Minister of Transport what is the capital cost of a complete traffic-light control installation at an ordinary crossroad and what is the annual maintenance charge?
Captain WallacesThe cost of installing traffic signals varies considerably according to the width of the road, the type of surfacing and other local conditions. At an ordinary crossroad where no special method of control is required the capital cost of a complete vehicle-actuated installation is usually between £650 and £850. The maintenance cost varies according to the cost of current and the number of signal faces provided, and in the case of an ordinary crossroad is about £70 to £85 a year.
