Clean Pass Vehicle Program

A pilot program started on March 1, 2006, which allows eligible single-occupant vehicles to travel in HOV lanes on the Long Island Expressway.

Eligible vehicle registrants are required to apply for Clean Pass identification stickers through DMV.

The logo for the sticker was incorporated onto the regulatory signs identifying when Clean Pass vehicles are permitted to enter the system.

The Police Enforcement program is in place, that includes monitoring the Clean Pass Vehicle regulations.

NYS DOT monitors HOV lane performance to evaluate impact of these additional vehicles in the HOV Lane.

HOV-LANE USER SURVEY 2006

Slide 22

METHODOLOGY

Videotaping of HOV lane traffic was conducted in May 2006 from four different locations in eastbound direction during HOV hours (6-10 AM and 3-8 PM)

Cameras were installed on bridges over LIE at the following locations:

  • Shelter Rock Road Overpass (Exit 35)
  • Pedestrian Bridge between Exits 40 and 41
  • Bagatelle Road Overpass (Exit 50)
  • Old Nichols Road Overpass (Exit 58)

Field Monitoring

Slide 24

METHODOLOGY (continued)

Videotaping data was processed and license plate information was extracted from each vehicle traveling in the HOV lane using a license plate retrieval system

A list of license plates was generated. After eliminating the duplicates, the list contained 13,712 plates.

The list was sent to NYS DMV to obtain the driver addresses for survey form mailing.

A total of 2,545 responses were received, which is near 20% of response rate.

Slide 25

SURVEY FORM

A Survey Form was developed that contained 14 questions about LIE HOV lane operations. The form was similar to the one used in previous surveys conducted in 1996, 1998, and 2000.

Additional question was included regarding Clean Pass Vehicles in HOV Lane.

The Survey Forms were mailed to driver addresses along with prepaid envelopes.

After receiving the responses back, the multiple choice answers were processed, sorted and tabulated.
