@callcress: I-95 in Fairfield County and the Science of Congestion #i95 #highway #traffic #fairfieldcountyct Traffic on I-95 in Fairfield County ranks among the worst in the nation, and it isn’t just accidents or bad drivers. Built in the 1950s for far fewer cars, the highway now operates beyond its limits. At “critical density,” traffic behaves like a fluid, creating backward-moving shockwaves that cause sudden slowdowns. The future solution may be smarter, networked cars that smooth flow and increase speed.
