Sensors and E-ZPass readers let engineers retime Midtown signals remotely, and phase one gained 10 percent. Average speeds still fell from 6.4 mph in 2010 to 4.6 mph by mid-2024.

New York City's transport department wired 110 Midtown blocks in July 2011 with microwave sensors, cameras and E-ZPass readers that clock cars between intersections, letting engineers at its Traffic Management Center retime signals remotely instead of sending a crew to each one. A 2012 expansion took the zone to about 270 blocks, and a 2024 state audit put the system at over 500 intersections. DOT measured a 10 percent travel-time gain in phase one. It did not hold: average Midtown speeds fell from 6.4 mph in 2010 to 4.6 mph by mid-2024, and only the 2025 congestion toll cut traffic, by 11 percent.

Live 📅 since 2011

📊 Impact

10 percent improvement in avenue travel times across the original 110-block zone in phase one, measured by NYC DOT on its own E-ZPass readers (preliminary, no control group). Now covers 500+ signalized intersections with 160 microwave sensors, 50 cameras and 100 E-ZPass readers.

🎓 Lesson

Retiming signals faster moves the traffic that is already there; it cannot make road space. Fourteen years of adaptive control did not stop Midtown speeds falling — putting a price on driving did.

↗ NYC DOT — Announces Expansion of Midtown Congestion Management System (2012)Operator source. Carries the impact sentence verbatim: 'Preliminary results of the first phase showed an overall 10% improvement in travel times on the avenues in the 110-block service area, as measured by E-ZPass readers.' Also supports the July 2011 install, phase-1 hardware (100 microwave sensors, 32 cameras, E-ZPass readers at 23 intersections), and the expansion to 270 blocks between 1st and 9th Avenues, 42nd to 57th Streets, fully operational September 2012.

↗ FHWA — Combating Bottlenecks: New York, Midtown in MotionFederal co-funder. Supports the cost split — a $1.6M improvement plan, $1M city funding and $600K federal — and independently confirms the 110-block area from Second Avenue to Avenue of the Americas, 42nd to 57th Streets.

↗ NY State Comptroller — Oversight of Selected Aspects of Traffic Controls (Follow-Up), 11 April 2024Independent state audit, the strongest currency evidence. Describes MiM in the present tense as in use by the Traffic Management Center, and reports DOT officials' current figures: over 500 signalized intersections, 160 microwave sensors, 50 traffic video cameras, 100 E-ZPass readers.

↗ NYCDOT — New York City Traffic Safety Network, ITS America (June 2025)Operator presentation confirming continued operation in 2025: MiM runs over the Traffic Safety Network, the wireless link that carries congestion data to the Traffic Management Center and signal-timing commands back to controllers, after NYCWiN was retired.

↗ Streetsblog — Midtown Traffic Slower Than Ever (8 July 2024)Counterweight. Source of the two speed figures: average Midtown speed 6.4 mph in 2010 against 4.6 mph in June 2024, from taxi and for-hire-vehicle speed data analysed by former city Traffic Commissioner Sam Schwartz — an outside analysis of city trip data, not a DOT publication.

↗ Regional Plan Association — Congestion Has Never Been Worse (11 June 2024)Independent research NGO corroborating the decline from a second direction, using NYC DOT taxi and FHV TPEP data: central business district speeds averaging about 7 mph in 2024, below the previous 2019 low.

↗ Governor of New York — First anniversary of congestion pricing (5 January 2026)Supports the closing clause: 27 million fewer vehicles entered the Congestion Relief Zone in 2025, an 11 percent traffic reduction, with faster river-crossing times and bus speeds up 2.3 percent inside the zone. Official self-reported programme figures.

↗ NYCLU — E-ZPass Readers (6 April 2015)Privacy counterweight to the toll-tag probe method. Found 149 E-ZPass readers around the city by 11 July 2014 and that NYC DOT had no policies or training materials on the storage, retention, destruction and use of information collected from them — which is why this entry does not describe the probe data as anonymous.
