Three Fairfield County cities made the list of 100 worst bottlenecks in the U.S.
All are on I-95.
- No. 67: Stamford
- No. 82: Norwalk
- No. 89: Bridgeport I-95 at RT 8
Other Connecticut bottlenecks on the list include I-95 at I-91 in New Haven (No. 44) and Waterbury (No. 81) I-84 at SR 8.
The data comes from GPS systems on trucks that ATRI converts for an ongoing analysis used to quantify the impact of traffic congestion on truck-borne freight at 300 specific locations.
On a state and local level, this research can inform local investment decisions that can directly improve supply chain efficiency.
This “bottleneck” analysis incorporates and synthesizes several unique components, including a massive database of truck GPS data at freight-significant locations throughout the United States, and an algorithm that quantifies the impact of congestion on truck-based freight.
The annual reports provide a chronological repository of mobility profiles, whereby congestion changes can be assessed over time. This, in turn, allows transportation analysts and planners to conduct performance benchmarking and identification of influential factors contributing to congestion and the requisite consequences on truck-freight mobility.
