Miami-Dade 2040 LRTP - Oct. 23, 2014

Appendices MIAMI-DADE LONG RANGE TRANSPORTATION PLAN UPDATE TO THE YEAR 2040 EYES ON THE FUTURE | E-17 Congestion and Mobility Bene ts Costs Implementation Timeframe • Increase capacity M • Short -term: 1 to 5 years (includes planning, engineering, and implementation) • Increase mobility • Reduce congestion by improving bottlenecks • Increase tra c ow and improve safety • Decrease incide nts due to fewer conflict points M • Shor t -term: 1 to 5 years (includes planning, engineering, and implementation) • Increase capacity • Improve mobility M • Medium -term: 5 to 10 years (includes planning, engineering, and implementation) • Slower -moving turning or exiting vehicles are removed from through lanes resulting in fewer delays for upstream traffic • Accelerating vehicles are provided more distance to reach the speed of through traffic, resulting in fewer delays caused by merging and weaving vehicles • In certain situations, can greatly reduce delays (caused by braking) for upstream vehicles during peak traffic flow periods M • Medium-term Right-of-way is an important factor in the time required for implementation and construction. • Increase capacity, reducing congestion in the short term • Long -term effects on congestion depend on local conditions • Reduced tra c and congestion on parallel streets H • Long -term: 10 or more years (includes planning, engineering, and construction) • Reduce Regional VMT • Reduce regional trips • Increase vehicle occupancy • Improve travel times • Increase transit use and improve bus travel times H • Medium -term: 5 to 10 years (includes planning, engineering, and construction) • Signi cant reduction in travel delays at high volume locations • Like ly elimination of car-train crashes • Decreased noise from train horns/whistles H • Medium-to long-term Implementation requires significant negotiation with railroads and local communities • Reduce arterial street network congestion • Reduce travel times & delay H • Long -term: 10 or more years (includes planning, engineering, and construction) • Provide connectivity • Carry tra c from local & collector streets to other areas H • Medium -term: 5 to 10 years (includes planning, engineering, and construction
