The migration of 2,800 signals was finalized in late 2012 What is wrong with current system? • Congestion reduces effective travel speed along the corridor • Without the proper vehicle detection, the system is not capable to address real time changes • Vehicle detection system is not up to date o loop detectors placed at the stop bar are not optimal to deal with congested/dynamic traffic flows Why it has taken so long? • Migration overlapped with recession period and drastic changes in travel patterns • New system and county might still be working on getting used to it What needs to be done? • Evaluate the current conditions and time accordingly • Need better detection system and better placement • Explore wireless detector systems to have greater flexibility What are we doing to help? • Schedule meeting with MDC PWD Signals and Signs Division staff • Evaluate state-of-the-art techniques to bring to Miami • Work with the County to deploy these techniques in the City as the Pilot Program Traffic Congestion — ATMS Signal Timings for US 1 at SW 27th Avenue Print Ode: N11 4614 TOD Schedule Report for2182: US 11SW 27Av Print Tare: 4:a9AM TOn Arta Imcado. 3r11r491n DRAWL HenN 2182 US18SW27Av 00W1 WA Sol Its PtLI 8111 1953. 5.09. lat Bit Hit 0162 NEL SWr SBL NBT 609E NET NBL SBT • Snit Enna Walk aon1 Wale laia.lontal Y0BE11 O13811alt 55182 Palo t Hal Phase eah' 1 2 a I 2 3 i3 2 3 1 NEL 0• 0• 0 0- 0 • 0 5- 5 •5 2- 2 2 8 • 8- B 30 • 30 • 30 4.9 2 2 SWr 7 . 7 . 7 23. 23 - 23 7 - 7 • 7 1 - 1 . 1 70. 70 • 70 0 . 0 . 0 4.9 2.2 3 SBL 0• 0- 0 0• 0- 0 5• 5- 5 2• 2 - 2 6- 5- 5 14 - 14 • 14 4.8 2 4 NBT 0 - 0• 0 0- 0 • 0 7 - 7 • 7 2.5 -2.5- 2.519 - 13- 13 60-60-50 4.8 22 6 SAL 0• 0• 0 0- 0 • 0 5- 5- 5 2• 2 • 2 8• 8• 8 18 • 18 - 18 4.9 2 8 NET 7 - 7 - 7 23 . 23 • 23 7 - 7 • 7 1 • 1 • 1 70 - 70 - 70 0 - 0 - 0 4.9 22 7 NBL 0- 0• 0 0• 0 • 0 5• 5• 5 2• 2 • 2 5• 5- 5 14 • 14 • 14 4.8 2 8 SBT 7 • 7 • 7 23- 23 -23 7 - 7 • 7 2.5 .2.5 •2513• 13- 13 50 • 50 • 50 4.8 2.2 Iaa_ Ammc Adtc Ada_ nureSak 37edoun Green Time Current 1 2 3 4 5 6 7 8 TOD Schedule Elba Cvele NEL SWT SSL NBT SWL NET NBL SST Bina Offset DMA 1 110 10 33 8 31 10 33 8 31 0 69 3 6 9 10 13 180 14 115 0 30 0 136 0 30 0 10 160 14 79 9 30 14 79 9 30 0 102 110 10 33 8 31 10 33 8 31 0 69 170 8 45 9 30 8 45 9 30 44 180 0 136 0 30 13 116 0 30 0 60 160 13 78 9 32 13 78 9 32 0 38 15 130 16 18 19 10 51 11 30 10 51 11 30 0 8 110 8 33 9 32 8 33 9 32 44 130 10 51 11 30 10 51 11 30 0 8 140 11 57 12 32 11 57 12 32 0 111 0 150 13 66 11 _32 13 66 11 32 0 124 71 130 12 46 13 31 12 46 13 31 0 17 72 130 14 43 13 32 14 43 13 32 0 107 24 130 76 52 7 17 9 69 0 31 0 89 26 140 15 54 12 31 15 54 12 31 58 28 130 24 54 7 17 9 69 0 31 0 113 29 140 14 74 0 31 14 74 0 31 66 Local TOD Schedule Time E.M.
