Adjustment Factors for Estimating Miles Traveled by Non-Motorized Traffic

Abstract: Traffic counts are an important piece of information used by transportation planners; however, while count programs are common for motor vehicles most efforts at counting non-motorized traffic – cyclists and pedestrians – are minimal. Long-term, continuous counts of non-motorized traffic can be used to estimate month of year and day of week adjustment factors that can be used to scale short-duration counts to estimates of annual average daily traffic. Here we present results from continuous counts of non-motorized traffic at 6 locations on off-street trails in Minneapolis, MN using two types of automated counters (active infrared and inductive loop detectors). We found that traffic volumes varied significantly by location, but the month of year and day of week patterns were mostly consistent across locations and mode (i.e., cycling, walking, or mixed mode). We give examples of how this information could be used to extrapolate short-duration counts to estimates of annual average daily traffic as well as Bicycle Miles Traveled (BMT) and Pedestrian Miles Traveled (PMT) for defined lengths of off-street trails. More research is needed to determine if non-motorized traffic patterns (and subsequently our adjustment factors) for off-street...

    Urban Arterials: Linking Traffic, Transit and Air Quality Data and Performance Measures

    The video begins at 2:00.

    View slides

    Abstract: Urban arterials often represent complex venues of transportation operations, co-mingling non-motorized users with transit services and a wide variety of land uses and traffic patterns. This presentation presents results related to the evaluation of a new Adaptive Traffic Control System (SCATS) on Powell Boulevard in southeast Portland. The presentation will discuss challenges and opportunities associated with the evaluation of new technologies and the development of comprehensive urban arterial performance measures.

    Speaker Bio: Miguel Figliozzi is an Associate Professor of Civil and Environmental Engineering at Portland State University. His diverse research interests include transit and traffic operations, bicycle and pedestrian modes, emissions and air quality modeling, and freight and logistics. He holds a MS from the University of Texas at Austin and a PhD from the University of Maryland College Park. Figliozzi is a member of the Transportation Research Board Network Modeling Committee, Freight and Logistics, and Intermodal Terminal Design Committees.

    Summary: This presentation is a showcase of various GIS tools developed for bicycle network analysis and planning. The showcase includes a tool for assessing community-wide bikeability, a tool for forecasting bicycle volumes based on street topology, and a tool for evaluating different bicycle improvement plans in terms of exposure to danger situations for bicyclists. The tools will be demonstrated with case study data. The presentation will include a review of the Highway Capacity Manual Bicycle Level of Service and a discussion about using bicycle and pedestrian data collected through citizen-volunteer count programs.
