Peter Gordon also weighs in on the question of congestion pricing on the 710 in Los Angeles.
Actually, we should be precise, as this is a research blog. This is a value-pricing, not a congestion pricing scheme. Congestion pricing generally reflects an scheme that prices the whole facility. Travelers must chose between using the facility and paying, or not using the facility at all.
Value pricing concerns a subset of lanes that travelers may opt into. They can stay in the free lane and deal with congestion (or no), or they can pay into lanes that have been priced.
