Needs Analyses
• Depends on the condition goal – Best Management Practice = low 80’s– MTC = 75 to BMP– OCTA = 85– MTA = 62 or 70
• Two philosophies– Implement one statewide standard– Let each agency determine goal
One Statewide Goal
• PROS– Consistent standard– Easy to compare
agency to agency
• CONS– One standard may not
reflect agency’s needs• County vs. city roads
– Perception of “forcing” standard onto an agency
Let Each Agency Decide Goal
• PROS– Agency decides what
is most appropriate for them
– 536 countries united by a common currency
• CONS– Difficult to compare
statewide– Needs assessment will
fluctuate when goals change
– Leads to inequities– Divide between have and
have-nots persist
Decisions
• What philosophy should we use?• If one statewide goal, what should
that be?
• Use best management practices as the statewide goal
Analysis Period
• Two factors to consider– How far do we look into the future?– How long to achieve the goal?
• How far?– SB 8 and SHOPP – 10 years– Regional Transportation Plans – 25 years
How Long to Reach Goal?

DECISION
• What analysis period should be used?
• Use 25 year analysis period; achieve goal within 5-10 years
