Exploration on traffic characteristics and gap assessment on midblock u-turn facilities

The idea of a Midblock U-turn Opening installation is to eliminate direct right turns. Midblock U-turning facilities are median openings on multi-lane highways. Uturning facilities aimed at easing traffic conflicts and pressures at highway intersections. This study is to identify the influence of mi...
