Downtown Vancouver Transportation and Emergency Management System (DVTEMS) PTV Vision User‘s Group Meeting Karen Giese Kean Lew

2 Outline Project Background Custom Interactions Model Demonstration

3 Project Background

4 What is DVTEMS? Planning level travel demand model Focus on pedestrian route choice Based on the VISUM platform Custom pedestrian & pedestrian-vehicle interactions Communication through visual platform Quantitative analysis

5 Dynamic Assignment DVTEMS Uses Dynamic Assignment (DUE) Key Benefits Accounts for Capacity Constraints Models Proper Interaction of Real Flows Models Impacts of Short-Term Measures Accounts for Special Event Temporal Characteristics

6 Custom Interactions Two-way Pedestrian Capacity > Allows Pedestrians to Utilize Both Sidewalks Along Street Vehicle-Pedestrian Interaction at Intersections > Uses Actual Crosswalk Flows from Assignment Pedestrian Inundation > Pedestrians Encroach on Vehicle Space > Vehicle Capacity Decreased > User-defined Parameters

7 Two-Way Sidewalk Capacity Capacity 2 Capacity 1

8 Two-Way Sidewalk Capacity Capacity South Sidewalk Capacity North Sidewalk

9 Two-Way Sidewalk Capacity Capacity 2 = Capacity North Sidewalk + Capacity South Sidewalk Capacity 1 = Capacity North Sidewalk + Capacity South Sidewalk Iteration 1

10 Two-Way Sidewalk Capacity Capacity 2 = Volume Eastbound / Volume Both Dir * Two Way Capacity Capacity 1 = Volume Westbound / Volume Both Dir * Two Way Capacity Iteration 2 onwards Until Converges

11 Vehicle-Pedestrian Interaction at Intersections ped volume Car Turn Capacity = f (ped volume)

12 Pedestrian Inundation Pedestrian Encroachment on Vehicle Lane(s) Parameters to be User-Defined (On or Off): > Inundation Allowed (Global Setting) > Pedestrian Link Inverse Density Threshold for Inundation (Global Setting) > On-Street Parking Allowed (Link Setting) > Pedestrian Allowed On Road (Link Setting)

13 Pedestrian Inundation Link Density > Inundation Threshold Link Density < Inundation Threshold Link Inverse Density > Inundation Threshold

14 Pedestrian Inundation Link Inverse Density > Inundation Threshold Capacity Required by Inundation

15 Pedestrian Inundation Link Inverse Density > Inundation Threshold ped volume

16 Pedestrian Inundation Link Inverse Density > Inundation Threshold Car Capacity = f (inundation capacity required)

17 Output Volume by Time Interval and Mode Pedestrian Density by Time Interval Pedestrian Level of Service by Time Interval Inundation Occurrence (Link Density > threshold and parameters allow for inundation) Travel Times To/From Stadium by Mode

18 Example Scenario Results: Volumes, Density, LOS Over Time Event 1 Start: 19:00 Pre-Event 2 Start:18:50 Event 2 Start:21:00 18:45

19 Example Scenario Results: Volumes, Density, LOS Over Time Event 1 End: 21:30 Event 2 End:23:00 23:30

20 Example Scenario Results: Link Closure 19:15
