Route 1Project Study Report
Overview
A report that describes the transportation problem and identifies the project scope, schedule and estimated cost so that the project can be programmed for environmental studies.
Two PSRs Developed
(1) Widening with Interchange Modifications
(2) Auxiliary Lanes with Ramp Metering
Range of Alternatives
• Widening for High Occupancy Vehicles (HOV)
• Widening for Mixed Flow Vehicles
• Widening for High Occupancy Toll (HOT)
• Interchange/Ramp Improvements
• Auxiliary Lanes at Various Locations
• Ramp Metering (with all build alternatives)
• No Build
Project Purpose
•To facilitate more efficient and safe operations of Route 1 as measured by congestion, travel times, mobility and accidents.
• To discourage reliance on single-occupant vehicle travel by improving travel conditions and interconnectivity for transit and high occupancy vehicles.
• To maximize the utility of any additional capacity that is created.

Green = Uncongested flow (v/c < 0.9), 60+ MPH
Blue = Near Capacity (0.9 < v/c < 1.0), 50 + MPH
Yellow = At Capacity (v/c = 1), Represents bottleneck location
Orange = Congested Flow - Resulting from upstream bottleneck, typically 0-35 MPH
