Our common regional arteries are also our common regional nightmare. A multiple-car accident on Interstate 5 backs up traffic in all directions on a rainy afternoon at rush hour, so... important meeting dates are canceled or delayed, kids are left at day care, truckers stew in their cabs over penalties for late deliveries. How to fix it?
Expand road capacity at key choke points? Overdue, but expensive and politically challenging. Add more transit and HOV lanes? Also important, but not well-suited to the increasingly suburb-to-suburb, errand-running environment we live in.
These are two reasons why technology is emerging as a short- and long-term answer to dealing with transportation gridlock.
