The Transportation Planning Rule Every City Should Reform

The Transportation Planning Rule Every City Should Reform

In the Portland Central City Transportation Management Plan, LOS is not used, but rather a vague requirement that intersection volume to capacity ratio is the measure that will be used. It offers the ability for v/c ratios that allow congestion at peak periods of the day. This has allowed tremendous flexibility for making decisions that follow policy as opposed to a letter grade. It has resulted in improvements that are leading the City towards its mode split targets.
