New York wired 3,000 fleet vehicles and 450 roadside radios, and spent 18 months just licensing them. Then the FCC gave most of the 5.9 GHz band to Wi-Fi — and the city's own filing called the equipment dormant.

Part of 1001 Smart Cities — 1,167 documented projects · 🏙️ 17 more in New York City · 🛡️ Safety & security guide · 🚲 Mobility projects

One of three federal connected-vehicle pilot sites. NYC DOT fitted about 3,000 city fleet vehicles and 12 MTA buses with radios that warned drivers of red-light running, unsafe lane changes and pedestrians, talking to 450 roadside units across three zones in Manhattan and Brooklyn; some 25 handsets gave visually impaired pedestrians crossing help. Licensing the roadside units alone took 18 months. Through 2021 half the fleet ran with alerts on and half stayed silent as a control. In November 2020 the FCC gave most of the 5.9 GHz band to Wi-Fi, and by July 2022 NYC DOT's own filing called its DSRC units dormant.

Completed 📅 2016–2021

📊 Impact

Red Light Violation Warning cut red-light running by 41 percent and Lane Change Warning cut the unsafe lane change rate by 46 percent, measured by USDOT's Volpe Center across the 3,000 equipped vehicles in 2021 against a control group whose alerts stayed silent. A separate independent evaluation for USDOT found little evidence that the deployment changed public agency efficiency at all.

🎓 Lesson

The pilot did the hard part: it produced controlled evidence that the warnings changed how people drove. What it could not control was the spectrum underneath it. A regulator reassigned the band, a $25 million deployment went quiet, and no one ever had to call it a failure — the city has a C-V2X waiver but no confirmed replacement on the street.

What the mapping says
Volpe's own assessment of 3,000 equipped vehicles across the 2021 operational year, with a control group whose alerts stayed silent — carried into USDOT's 2024 executive briefing as 'reduced red-light running by 41%' and 'reduced unsafe lane change rate by 46%', both cited to benefit record 2022-B01691.
Caveat
A behavioural surrogate, not a crash count. Volpe analysed data the deployment itself collected, and the alert-response measurement covers a single pandemic-affected year.
