Drive times and variable-message signs

Every now and then I send in a question to the Getting There column in the Seattle P-I. Surprisingly enough, they usually print it... here's this week's (it's the last question).

I find it interestng that WSDOT is using an old VAX for its variable signs. With all of the new signs they've recently put in on Washington freeways, I thought they'd have something a bit more modern. Oh well...
