• Abstract:
  The Colorado Department of Transportation (CDOT) adopted the Bicycle and Pedestrian Policy directive in 2009
  
  stating that "...the needs of bicyclists and pedestrians shall be included in the planning, design, and operation of
  
  transportation facilities, as a matter of routine..." While well intentioned, this policy directive remained difficult to
  
  fulfill without sufficiently accurate estimates of bicycle and pedestrian volume on CDOT facilities. This research
  
  project enables CDOT to answer the question of whether or not these road users are being adequately
  
  accommodated by establishing Colorado-specific methodologies for estimating bicycle and pedestrian volumes via a
  
  limited sample of existing counts. Because it is not economically realistic to collect continuous count data
  
  throughout the entire CDOT system, there is a need to establish procedures for handling bicycle and pedestrian data
  
  and calculations as well as methods for estimating annual bicycle and pedestrian use from short-term counts. This
  
  work will facilitate improved use of CDOT’s existing investments in collecting continuous and short-term bicycle
  
  and pedestrian count data. It will also enable CDOT to better understand the needs of bicyclists and pedestrians as
  
  well as best allocate limited resources in order to properly meet those needs.
  
  Implementation
  
  Using the factoring method presented in this report, CDOT can automate the estimation of AADB and AADBP, just
  
  as is currently done for motor vehicle traffic. Since the method is essentially the same and the grouping of the sites
  
  can be automated, this should not require significant staff time. By publishing the non-motorized traffic counts and
  
  annual average daily bicyclists (AADB) and annual average daily bicyclists and pedestrians (AADBP) estimates on
  
  its website, CDOT can share this processed data with local agencies throughout the state.
