K3−2: Statewide Work Zone Inspection Program


The New York State Department of Transportation (NYSDOT) is committed to an aggressive work zone safety inspection program which monitors worker and traveler safety performance indicators. Each year a statewide survey of work zone traffic control is conducted by inspecting a representative sample of construction, maintenance and permit projects. The purpose of the Statewide Work Zone Inspection Program is to gather information which enables NYSDOT to evaluate the overall adequacy of work zone traffic control on department projects and identify areas where improvements are needed.

The evaluation includes design, implementation, and maintenance of work zone traffic control and assesses compliance with department standards, practices, and policies. The inspections are done by a team of Central Office and Regional Office staff from the various program areas responsible for work zone safety. The inspections rate individual work zone safety and traffic control elements in each work zone based on a 0 through 5 point rating system. A checklist is used for each project to ensure that critical elements are reviewed and documented. Overall performance is evaluated by determining the percentage of individual work zone traffic control elements that receive a 4 or better rating. Training and revisions to specifications, standards and policies, or other initiatives are developed each year based on deficiencies that are observed during the field reviews.


The safety program ensures the continual improvement of work zone traffic control on New York State Highways through a process of evaluating uniformity and compliance with state standards.
