Study Goals

• Increase person throughput and travel time reliability

• Enhance economic vitality of the region

• Enhance safety and mobility by providing congestion free options

• Enhance/maintain advantages for transit, taxi cabs, airport shuttles,

park and ride, ride sharing, and non-motorized connections

• Use existing infrastructure, right-of-way, and performance based

principles to the maximum extent possible as well as lower cost-high

return on investment strategies

• Coordinate and provide synergies with other planned and programmed

investments

• Educate, inform, involve, and adapt to public stakeholders at strategic

decision making points throughout the duration of the study
