E-16| MOBILITY OPTIONS 2014 Congestion Management Process Update Cambridge Systematics, Inc. (7) Highway Strategies Strategies/Projects Increasing Number of lanes without Highway widening This takes advantage of “excess” width in the highway cross section used for breakdown lanes or median. Geometric Design Improvements This includes widening to provide shoulders, additional turn lanes at intersections, improved sight lines, auxiliary lanes to improve merging and diverging. Interchange modifications to decrease weaving sections on a freeway, paved shoulders and realignment of intersecting streets. Consider revising to discuss added segment capacity and added intersection capacity . Super Street Arterials This involves converting existing major arterials with signalized intersections into “super streets” that feature gra de- separated intersections. Acceleration/Deceleration lanes • Deceleration lane provided on a freeway just before an exit o -ramp allowing vehicles to reduce speed outside the through-lanes • Acceleration lane provided as an extension of a freeway on -ramp or an arterial street turn-lane for vehicles to increase speed and merge more smoothly into the through-lane Highway Widening by Adding Lanes This is the traditional way to deal with congestion. HOV Lanes This increases corridor capacity while at the same time provides an incentive for single-occupant drivers to shift to ridesharing. These lanes are most effective as part of a comprehensive effort to encourage HOVs, including publicity, outreach, Park-and-Ride lots, and rideshare matching services. Grade separated railroad crossings Roadway underpass or overpass of a railroad line . New Freeways Construction of new, access-controlled, high-capacity roadways in areas previously not served by freeways. New Arterial Streets Construction of new, higher-capacity roads designed to carry large volumes of traffic between areas in urban settings.
