CAPACITY IMPROVEMENTS ON URBAN EXPRESS ROADS IN FRANCE

How to improve urban expressway capacity on land strips constrained by urban development? To reflect on this subject, the French National Road Directorate commissioned a study group, comprising experts in road design, management, traffic regulation and safety. In order to gain one lane in the cross-section, the group investigated two contrasting options either to remove the hard shoulder, or keep it and reduce other components of the cross-section. The study group clearly proposed that the hard shoulder should be kept because of its significant functions, while reducing the width for each of these components and conditions for their use. In order to check the validity of these proposals, a trial was carried out, under real conditions, on the A6a motorway. As French knowledge of highway capacity (especially for narrow lanes) is insufficient, the study group is preparing a programme for trials and data collections.
