    In response to the limited awareness surrounding Bus Rapid Transit (BRT) and the A Line, this study provides answers to questions regarding the operation and public perception of the A Line in the Twin Cities region, Minnesota. Two traffic scenarios were studied, one for high-volume oversaturated traffic during the Minnesota State Fair, and a second for normal operating conditions. For both scenarios, intersection queue length and traffic flow rate were compared before and after an A Line bus. It was found that in both time periods (Fair and non- Fair), the dwelling of an A Line bus during a green traffic signal did not have a statistically significant impact on intersection queue length or traffic-flow rate at either of the two researched stations. From an analysis of the 2016 On-Board Survey, it was determined that passengers are more satisfied by the overall service of the A Line than local buses while there is not a significant difference in overall satisfaction compared to express buses, light rail and commuter rail. The top three important service attributes to overall satisfaction are “paying my fare is easy,” “hours of operation,” and “handling of concerns/complaints.” It is recommended that the transit agency improve the attributes that have higher relative influences and lower mean performances. Based on this criterion, the attributes that should be given priority are “shelter/station conditions and cleanliness” and “behaviors of other passengers and atmosphere on board.”

    Uncontrolled Pedestrian Crossing Evaluation Incorporating Highway Capacity Manual Unsignalized Pedestrian Crossing Analysis Methodology
    (Minnesota Department of Transportation Research Services & Library, 2014-06) Nemeth, Bryan; Tillman, Ross; Melquist, Jeremy; Hudson, Ashley
    This report provides a procedure for the evaluation of uncontrolled pedestrian crossing locations that takes into account accepted practice, safety and delay. Safety considerations have been paramount to the analysis of crossings but delay is often not considered. The Highway Capacity Manual (HCM) provides a methodology for determining delay that can be included in the analysis of a crossing location. The analysis procedure takes into account previous research procedures and adds in delay considerations to develop a methodology appropriate for use by jurisdictional agencies in the evaluation of what is needed for treatments at uncontrolled pedestrian crossings. The evaluation procedure developed runs through a multi-step process from field data review through the consideration of appropriate treatment options. The evaluation procedure takes into account field data collection; safety/crash history; stopping sight distance; HCM Level of Service (LOS); pedestrian sight distance; origins and destinations/alternate routes; access spacing and functional classification; roadway speed and pedestrian use; FHWA guidance for placement based on safety considerations; school crossings; and appropriate treatment options. Treatment options include four different classes: Signing and Marking Treatments; Traffic Calming Treatments; Uncontrolled Crossing Treatments; and High Level Treatments.
