Background
Agencies tend to select projects that, once constructed, do not generate ridership levels that warrant their construction. In short, many project projects are overbuilt and a less costly alternative would satisfy the project need.
A variety of political, financial, and accounting incentives support the construction of projects whose capacities far exceed demand, including:
- Overestimated ridership from forecast modeling inputs that do not correspond with actual travel behavior
- Unanticipated construction costs
- Preference for large, splashy projects
- No incentive to manage project costs because others are footing the bill
Improve modeling
Improve cost estimation
- Conduct extensive engineering studies before deciding on alternative
- Reach out to stakeholders
- Use historical cost estimates as comparison
- Consistently measure across projects
