What is the Long-Distance High-Speed Green Route?

[DiNatalie]

"High-Speed Green" is displayed as dark green on the map, representing low-traffic and smoother road conditions compared to general "smooth" traffic scenarios, with fewer vehicles on the road, larger gaps between cars, and faster travel speeds. Below is relevant information: Expressway: Urban roads equipped with a central divider, featuring four or more motor vehicle lanes, with partial or full use of interchanges and controlled access, designed for higher-speed vehicle travel. Arterial Road: Main roads connecting various urban districts, primarily serving traffic functions. The design speed for arterial roads is 40-60 kilometers per hour.
