Punishes last-in, inhibits infill, pushes development outward“Solves” local congestion, exacerbates regional congestion

Problems with LOS as a Measure of Transportation Impact
10
Analysis of infill development using LOS
Relatively little vehicle travel loaded onto the network
Chris Ganson, CA OPRJune 2015

Analysis of infill development using LOS
Relatively little vehicle travel loaded onto the network
…but numerous LOS impacts
June 2015
12
Analysis of greenfield development using LOS
Typically three to four times the vehicle travel loaded onto the network relative to infill development
…but relatively few LOS impacts
Traffic generated by the project is disperse enough by the time it reaches congested areas that it doesn’t trigger LOS thresholds, even though it contributes broadly to regional congestion.

Statewide Implementation
Urban• Streamline infill• Streamline transit and active transportation projects• Lots of mitigation options, greatest percent VMT reduction
Suburban• Problems with LOS, benefits of VMT apply here too• Many mitigation options; greatest absolute VMT reduction
Rural• Again, problems with LOS, benefits of VMT apply here too• Some mitigation options at the plan level, some at the project level• VMT mitigation limits growth of small towns
All: Benefits to environment, health, public cost, private expenditures

Use Ad-hoc, LOS-triggered mitigation (highly problematic)
Use LOS to plan roadway capacity; use number of units or square footage to estimate project impact (not ideal)
Use LOS to plan roadway capacity; use VMT to estimate project impact (okay)
Use accessibility/connectivity metric to plan network; use VMT to estimate project impact (ideal)
