1 Traffic Engineering Applications of Drone John Manix, PE, Senior Traffic Engineer, PBS Derrick Westoby, Unmanned Aerial Survey Program Lead, PBS pbsusa.com 1

2 If a picture is worth a thousand words what does this say? Video collection process Drone hardware Collect the data Clearance process pbsusa.com 2

3 Drone Hardware Considerations Drone Type Fixed Wing or Multi-Rotor Battery Flight Time Limitations Camera Angles & Positions Clearances and Waivers FAA waivers may be required Airspace waivers 90+ days Other waivers hard to obtain ALL commercial flights require a part 107 license. pbsusa.com 3

4 Myra Road and US 12 Trucks and Roundabouts 1x pbsusa.com 4

5 Trucks and Roundabouts 10x Emerging with High Potential UAS is a valuable tool for: Explaining complex issues Understanding safety conflicts Collecting smarter data pbsusa.com 5

6 Explaining Complicated Transportation Issues Car wash site has existing driveway (#2) 75 feet from busiest intersection in Walla Walla. Proposed driveway #3 is with WSDOT right-of-way restrictions. Site Driveway Close to Traffic Signal This large commercial site may not be economically viable with right-in, right-out of driveway? pbsusa.com 6

7 Queuing Results How does it model? 2018 SimTraffic modeling of intersection without the project pbsusa.com 7

8 UAS Shows Gaps in Traffic and Validate Model Modeling with Project pbsusa.com 8

9 But will it be safe? What is the safe stopping distance? Safety is a function of vehicle speed Data from the Sky pbsusa.com 9

10 Lessons Learned Our traffic modeling accurately estimated queue length. A full-access driveway has gaps to accommodate the car wash traffic. It is safe. Traffic speeds are slow speeds. Understanding Safety Conflicts pbsusa.com 10

11 Level of Service & Delay for Alternatives Traffic Signal Alternatives pbsusa.com 11

12 UAS Evaluation Mini-Roundabout Alternative pbsusa.com 12

13 Lessons Learned Verified delay estimates Showed effects of platoon and short head-way Showed need for left-turn lanes Supported mini-roundabout alternative Collecting Smarter Data pbsusa.com 13

14 Manual Parking Survey Results May 23, Parking Area 8:30 AM 9:30 AM 10:45 AM Staff Parking Data Collection via UAS Parking Area 4 Only one vehicle school parking pbsusa.com 14

15 Parking Data Collection via UAS Parking Area 8 three vehicles not related to school parking Parking Data Collection via UAS Parking Area 9 two parked cars related to the school. pbsusa.com 15

16 Parking Data Collection via UAS Parking Area vehicle related to Kennewick YMCA School-in and Out Data Review May 23 School in session Parking 8:30 A 9:30 A 10:45 A Area Aug 20 School out/summer Parking 9:00 A 9:30 A 10:00 A Area pbsusa.com 16

17 Lessons Learned Get your request in early to FAA for clearance to fly. Aerial parking surveys can provide: Parking occupancy Turn-over data Parking distribution data All data recorded on an aerial! In Closing: What does UAS offer? For traffic For safety evaluations For data collection New details not seen from still or ground mounted cameras An important resource for understanding vehicle interaction Doesn t replace conventional data, but makes the data smarter pbsusa.com 17

18 Thank you! Questions & Answers PBSUSA.COM/UAS HELP WANTED! Please take a few minutes to use the evaluation form on the mobile app and provide your feedback on this session! Evaluations help us select sessions for future conferences and provide valuable feedback for conference planners & speakers. Thank you! pbsusa.com 18
