2010 Highway Capacity Manual (HCM) Pedestrian Level of Service (LOS) at Uncontrolled Crossing Locations Intersection and Mid -Block Crossings Crossing Location: Variolite/161st Ave Date: 5/4/2017 City, State: Ramsey, Mn Scenario: Reviewer(s): Grant Riemer Agency: City of Ramsey Project Number: ID #: The following is the base information needed to complete the analysis. If this is a one -stage crossing, use only Crossing 1. If this is a two -stage crossing, each stage must be evaluated separately using Crossing 1 and Crossing 2. Crossing 1: Evaluation Inputs: defaults: Input Table: L = crosswalk length (ft) L = Sp = average pedestrian walking speed (ft/s) Sp = 3.5 Sp = is = pedestrian start-up and end clearance time (s) is = 3.0 is = V = vehicular hourly volume (veh/hr) V = v = pedestrian flow rate (ped/s) vp = 0* vp = v = vehicular flow rate (veh/s) = V/3600 v = V/3600 v = We = crosswalk width (ft) We = 8.0 We = N = number of through lanes crossed (Integer) N = INT(L/11) N = *no platooning observed Crossing 2: (only used for two -stage crossings) Evaluation Inputs: defaults: Input Table: 52 3.5 3 74 3.00 0.020 10.0 2 L = crosswalk length (ft) Sp = average pedestrian walking speed (ft/s) is = pedestrian start-up and end clearance time (s) V = vehicular hourly volume (veh/hr) vp = pedestrian flow rate (ped/s) v = vehicular flow rate (veh/s) = V/3600 We = crosswalk width (ft) N = number of through lanes crossed (Integer) Crossing Treatment Yield Rate My = motorist yield rate (decimal) L= Sp= 3.5 Sp= is = 3.0 is = V= vp= 0* vp= v = V/3600 v = We = 8.0 We = N = INT(L/11) N = *no platooning observed Input Table: My = Entering data into the tables above will populate the evaluation tables in Microsoft Excel.
