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
