Mitigation of congestion at a traffic bottleneck with diversion and lane restrictions

► Congestion mitigation in traffic flows simulated with advanced travel information. ► Three-phase theory applied to a two-lane highway with an off-ramp and an on-ramp. ► Congestion at the on-ramp bottleneck reduced by diversion to the off-ramp. ► Restrictions on lane changing near the on-ramp improves flow.
