Erica Terrini 0 0 Article rating: No rating

IF YOU'RE A human driver, road construction probably annoys you: one more thing clogging traffic on your way home. If you're a self-driving car, though, it can be devastating. Work zones flummox the future rulers of our roads because they override or obliterate the sturdy markers by which the vehicles are taught to navigate. With no warning, they enter a world where cones trump double yellow lines, bollards replace curbs, and construction worker hand signals outweigh traffic lights.

A number of States have been approached about erecting signs for the USDOT’s Marine Highway program, administered by MARAD. The Marine Highway system essentially promotes transport of goods via navigable waterways as an alternative to landside highways. Each Marine Highway waterway is designated with a route number that corresponds to the nearest Interstate highway that it roughly approximates as an alternative route between destinations. The route number is preceded by “M-” (e.g., M-95 runs along the East Coast as an alternative to I-95).
