TRL Limited was commissioned by the Highways Agency to investigate the potential use of route hierarchies and Condition Indicators for pedestrian routes in the management of footway maintenance. With the total number of defects identified being in excess of 60, the defects have been categorised into user-related surface defects and personal security, user satisfaction and comfort defects based on Safety, Accessibility, Comfort and Environment parameters. An attempt has been made to combine defects with user related parameters to formulate possible Condition Indicators for Safety, Accessibility, Comfort and Environment. Proposals are made for a method of combining these Condition Indicators into an overall Indicator for sub-lengths of footway, as well as for the whole route of a single footway category. The Indicators may be suitable for use at network and project levels. They may also be derived from sample surveys undertaken on part of a footway route. (Author/publisher)
