Traffic Congestion

• Traffic congestion is becoming the single most
  difficult problem on American roads. Highway
  congestion is increasing as traffic increases
  across the country at more than four percent
  annually, while highway capacity often remains
  the same year after year. In North Carolina
  these conditions are observed near interstate
  highways that are in or near the three major
  urban areas, Charlotte, the Piedmont Triad and
  the Research Triangle. When it is possible,
  adding lanes is often only a temporary solution
  since traffic continues to grow.

Traffic Reduction

• One way to reduce traffic congestion is to
  install high occupancy vehicle (HOV) lanes.
• Provide a free flowing lane
• Reduce travel time
• Increase driving ease

5
High Occupancy Vehicle Lanes

• Physically located in the center of most major
  freeways, HOV lanes typically are
  barrier-separated roadways that allow buses,
  vanpools and carpools to move higher volumes of
  passengers to and from locations.

6
High Occupancy Vehicle Toll Lanes

• HOT lanes are lanes that are open to carpools,
  vanpools, transit, and toll-paying solo drivers.
  Tolls for HOT lanes are set to assure that these
  lanes keep flowing even when regular lanes are
  congested.

Strengths of HOT Lanes

• Reduced congestion in general purpose lanes
• Easily fine-tuned to preserve free flow
  conditions
• Reduction of new construction in conversion of
  existing HOV lanes
• Usage of HOT lane reduces congestion for transit
  and emergency vehicles
• Additional revenue to pay for transportation
  improvements
• Reduction of harmful externalities

The Proposed Managed Lane

• North Carolinas team of researchers and
  engineers proposed a managed lane that will be
  reversible, eastbound in the morning and
  westbound in the evening. The lane will be
  separated from the usual general purpose lanes by
  candle stick markers. People will only use the
  lane if their car
• 1. has at least 2 passengers (no toll required)
• 2. pays a toll to use the lane.

Current Status

• The project team is collecting data on the
  opinions of commuters where the HOT lane is
  proposed and implementing a study of the opinions
  of stakeholders in the Triad.
