Transportation Planning Process

A transport planning process is the process of defining future policies, objectives, investments, action plans and spatial planning projects to meet future transportation-related needs. As is being done today, it is a collaborative process that incorporates the views of a wide range of stakeholders including various central and local government agencies, state-owned enterprises and the private sector. Transport planners, planning organizations or federal agencies use a multidisciplinary approach to analyze a variety of alternatives and impact on the transportation system to contribute to profitable outcomes.

• Lane width = 11 ft
• Right-side lateral clearance = 6 ft
• Analysis segment is 0.32 miles long with a 4.0 % grade
• v = 3500 veh/hr (primarily commuter traffic and familiar drivers)
• PHF = 0.95
• Traffic composition: 15 % Trucks, 2 % RVs
• One cloverleaf interchange per mile (ramp density = 4 ramps/mile)
