EEM1 (road infrastructure) Appendix 4 - Travel time values

Introduction

This appendix contains travel time values for vehicle occupants, passenger transport users, pedestrians, cyclists, and freight vehicle travel time. The road user values are used to produce composite travel time values for the different road categories for uncongested and congested traffic conditions. Values and procedures are also provided to calculate the values for changes in road user journey time reliability.

The travel time benefits for a project option shall be calculated as the difference between the do minimum and option travel time costs as follows:

Total travel time savings = base travel time benefits for improved flow

+ travel time benefits for reduced traffic congestion (if applicable)

+ travel time benefits for improved trip reliability (if applicable).
