Latest insights from US traffic data and analysis company INRIX reveal that small changes in the timing of traffic lights can provide significant reductions in travel times while eliminating idling and wasted fuel.
According to the recently released INRIX US Signals Scorecard, nearly 7% of a trip’s delay is located at signalized intersections, leading to a collective 17.25 million hours sitting at traffic lights in the United States every single day.
Furthermore, problems tend to occur in focused areas, leading to direct localised exposure to toxic air pollutants. For example, 4 out of the top 5 counties for delay per vehicle are located in New York City, while the Los Angeles Metro region is home to more than 1.7 million hours of delay each and every day.
In addition to the Signals Scorecard, INRIX has calculated the estimated carbon emissions at the Top 25 intersections for total daily delay. In first or worst place is West Flamingo Road & South Las Vegas Boulevard, at which drivers burn 419 gallons per day, driving, crossing, stopping, idling and accelerating across the intersection, emitting in the process 3.7 tonnes of CO2 into the atmosphere. To put this in perspective, that is about 80% of the UK’s per capita average annual total CO2 emissions – at one junction in one day.
