      <title>An assessment of traffic safety culture related to driving after cannabis use</title>
      <link>https://trid.trb.org/View/1439979</link>
      <description><![CDATA[The purpose of this project was to develop a better understanding of the traffic safety culture (i.e., shared values, beliefs, and attitudes) of driving under the influence of cannabis (DUIC). A survey was developed based on an augmented integrated model of behavior and was implemented using mailed and internet-based methods. Adults age 18 and older from the U.S. responded. Two states with legalized recreational use of cannabis (Colorado and Washington) were oversampled. The survey measured DUIC behavior, intention, willingness, attitudes, behavioral beliefs, perceived norms, and perceived control. About half of the individuals who had used cannabis in the past 12 months reported driving within four hours of use. Partial correlation coefficients showed that many components of the model correlated with willingness to DUIC. Significant differences in attitudes and beliefs were found between non-users of cannabis, users of cannabis, and those who DUIC. No differences in beliefs or attitudes were found between states with and without legalized recreational use laws nor between states with legalized medical use laws. Recommendations for strategies to reduce DUIC are provided.]]></description>

      <title>Liability Aspects of Bikeways</title>
      <link>https://trid.trb.org/View/917680</link>
      <description><![CDATA[This digest addresses the liability of public entities for bicycle accidents on bikeways as well as on streets and highways.  As the American Association of State Highway and Transportation Officials' "Guide for the Development of Bicycle Facilities" states, "[t]he majority of bicycling will take place on ordinary roads with no dedicated space for bikes."  Further, the report reviews the federal laws that encourage the designation and use of bikeways; the elements of a claim in tort against a public entity for a bicycle accident, whether on a public street or some type of bikeway; defenses to bikeway accidents under tort claims acts and applicable to public entities; immunity for bicycle claims under some state recreational use statutes that in a majority of states are applicable to public entities; and public entities' laws and policies on the accommodation of bicycles on streets and highways and the designation of bikeways.  Some discussion is based on responses to a survey of public entities, including public entities that designate bikeways.  This report will be useful to attorneys, transportation officials, risk managers, planners, maintenance engineers, financial officers, policy makers, and all persons interested in the relative rights and responsibilities of motorists and bicyclists on shared roadways.]]></description>
