How North Fork traffic is slowing
The average speed for motorists along a stretch of road is one measure of how crowded that route can be from hour to hour.
Using data from Roadway Analytics, a traffic data program from Inrix, Newsday compared hourly average speeds on Saturdays and Sundays in July 2017 with the average for the same days and times in the previous three years. This was done for four stretches of road on the North Fork that are among several trouble spots. The measurements, which take into account the time vehicles were stopped for lights, etc. begins at 10 a.m. and ends at 7 p.m. Here’s the data, starting with the roads with the biggest delays. Mouse over charts for details.
#1: Average miles per hour on Love Lane, Mattituck
Between Sound Avenue and County Road 48. In each of the nine hourly blocks, beginning at 10 a.m., traffic was slower in 2017.
The difference was greatest in the hour beginning at 2 p.m., when the average speed for 2017 was nearly 22 percent lower than average of the three prior years.
#2: Small stretch of Route 25 in Riverhead
From Old Country Road to Cross River Drive. In each of the nine hourly blocks, beginning at 10 a.m., traffic was slower in 2017.
Again, in the 2 p.m. hour, the average speed was just under 22 percent lower in 2017 than the average of the three prior years.
#3: Route 25 from South Jamesport Avenue to Sound Avenue
In each hour, traffic was slower in 2017. The difference was greatest in the hour beginning at 5 p.m., when the 2017 speed was nearly 7 percent slower than the prior years’ average.
#4: County Road 48 between Elijahs Lane and Depot Lane, Southold
Despite being a heavily traveled road, the differences in speed here were smaller, but traffic was still slower in 2017 in six of the nine-hour blocks.
The biggest drop came in the hour beginning at 10 a.m., when speeds were down 4 percent in 2017 compared with the average for the prior three years.
