Tailgating alerts from Mobileye fall in New York taxis

In a TLC trial, tailgating alerts from Mobileye's system fell from 100 per 100 miles in July 2015 to between 20 and 40 from January 2016. Crash rates in the trial did not clearly fall.

  • 2 a person

    Tailgating alerts in the fitted cabs fell from 100 to between 20 and 40 per 100 miles, a measured change in how closely drivers followed.

  • Not rated society

    Crash rates for the vehicles in the trial did not show a clear decline, so no gain in road safety is shown.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

An independent regulatory document supports the benefit.

Compared with

Alert rates in the same fleet early in the trial. Measured.

Without the system
100 alerts for each 100 miles traveled (or one alert per mile) in July 2015
With it
between 20 and 40 alerts per 100 miles starting in January 2016
The system’s part
Not isolated. The TLC tracked alert rates in the fitted cabs over time without a comparison group, so the fall cannot be tied to the system alone. Shared vehicles and changes in the fleet could also move the rates. The TLC describes a sensor that detects vehicles, pedestrians and lane markings but does not mention machine learning.

    New York City Taxi and Limousine Commission. Vehicle Safety Technology Final Report. March 2018.

    Headway Warning rates—alerts for tailgating—decreased the most over the course of the Pilot, from 100 alerts for each 100 miles traveled (or one alert per mile) in July 2015 to between 20 and 40 alerts per 100 miles starting in January 2016.
    The crash rates per participating vehicle did not show a clear decline over the course of the program.

Details

AI system

Workflow

A forward-facing sensor on the windshield monitored the road continuously. Drivers got sound and visual alerts and a vibrating seat when they followed too closely or left a lane without signaling. A black box recorded the alerts for the TLC's analysis.

Follow-up

Conditions for replication

Drivers must be exposed to the alerts consistently. Fleets may need to use the data to coach drivers for behavior to change.

Entry details

Sector

Road safety / for-hire vehicles.

Purpose

Mobileye built its aftermarket system to warn drivers of lane departures, close following and possible collisions.
