Let‘s investigate what LTSA Team did? 9
Field test 1
Field test 2
- Campus FH Potsdam - Focus on VRU - Testing various detection and tracking sensors - No cars
- Road intersection in Potsdam - Cont. testing of various sensor and mounting positions - Including normal road traffic, buses, tram - V2X communication

Field test 1 • Installation and commissioning in September 2021 • Testing of different sensors
11
Field test 1: Example Sensor • VRU Detection by thermo camera • Translation of thermo data in objects • Identifiying trajectories
01.03.2022
12
Field test 1: Example TROL • Converting of video data in Tracked Object List (TROL)
• VRU detection and tracking via VITRONIC video sensor

… first results from LTSA field test #1 and #2 18
Field test 1
Field test 2
- Various sensors delivery good results for VRU detection and tracking
-
Sensor results confirm initial conclusions from Field test 1
- Cost levels
-
For the LTSA Application: Scenario Definition such as collision warning is important
- Data privacy and cost considerations favour video sensors
-
To do’s: integration of data into traffic light control and V2X warnings
- Covid challenges
-
Further Tests / Covid challenges
- Anonymsiation of data is key (TROL)
