Miami-Dade 2040 LRTP - Oct. 23, 2014

Appendices MIAMI-DADE LONG RANGE TRANSPORTATION PLAN UPDATE TO THE YEAR 2040 EYES ON THE FUTURE | E-21 Congest ion and Mobility Bene ts Costs Implementation Timeframe • Increased capacity, e ciency on arterials • Imp roved mobility on facility • Improved travel times and reduced delay for through tra c • Fewer incidents L • Short -term: 1 to 5 years (includes planning, engineering, and implementation) • Increased capacity, e ciency • Improved mobility and safety on facility • Improved travel times and reduced delay for all tra c M • Short -term: 1 to 5 years (includes planning, engineering, and implementation) • Increased capacity, e ciency • Improved mob ility on facility • Improved travel times and reduced delay for through tra c • Fewer incidents due to fewer con ict points M • Short -term: 1 to 5 years (includes planning, engineering, and implementation) • Increase capa city, efficiency on arterials • Improve mobility on facility • Improve travel times and decrease delay for through tra c • Decrease incidents M • Short -term: 1 to 5 years (includes planning, engineering, and implementation) • Increase capacity, e ciency on arterials • Improve mobility on facility • Improve travel times and decrease delay for through tra c • Decrease incidents M • Short -term: 1 to 5 years (includes planning, engineering, and implementation) • Greater number of vehicles can pass through the intersection in given amount of time, resulting in a lower level of travel delays and stopped time • Can reduce the likelihood of rear -end crashes M • Medium-term Agencies must be sure to plan for possible time needed to obtain right-of-way. • Greater capacity than traditional 3 or 4-way intersections in many situations • Fewer crashes over time • Lower air pollutant emissions due to fewer stopped vehicles M • Medium-term Completion time for a replacement roundabout is related to the amount of planning and public outreach time needed and the right-of-way acquisition process • Increased capacity, e ciency • Improved mobility on facility • Improved travel times and reduced de lay for through traffic • Fewer incidents due to fewer con ict points H • Medium -term: 5 to 10 years (includes planning, engineering, and implementation) • Increased capacity and fewer stops • No stops for through tra c • Fewer turning movement con icts H • Medium-to long-term Completion of a grade-separated intersection can take from five to 15 years, including planning, engineering, environmental analysis and construction phases.
