16. Abstract
Traffic monitoring in recreational areas is often challenged by distinct traffic and roadway characteristics and the multitude of agencies responsible for the management of Federal lands and/or the collection of supporting traffic data. These challenges are exacerbated by a lack of consistent procedural guidance; existing national traffic monitoring guidelines lack sufficient direction and detail for recreational travel.

In an effort to improve/lend consistency to traffic monitoring in recreational areas, the Coordinated Technology Implementation Program tasked the Office of Federal Lands Highway-Federal Highway Administration (FHWA) with conducting an assessment of the nationwide practices for recreational traffic data collection. A review of pertinent literature related to recreational traffic data collection was conducted. A targeted survey of various State and local agencies responsible for traffic monitoring was administered. A workshop focused on traffic monitoring in recreational areas was also conducted. Key findings from these activities are briefly described herein.
