There is a proposal called "Congestion Pricing" from our transportation agencies to turn the HOV Lanes into Toll Lanes. I was going to blog about it. TheRealZajac did an excellent job articulating the issue over at the Foothill Cities Blog. You can read about it it here.
Regional traffic issues are complex. But one thing is clear, if you want less traffic on the highways, offer alternative modes of transportation which will get us out of our cars.... How about extending the Gold Line eastward?? Many who work in Downtown LA will be glad to give up their cars and ride the train to work and home.
