Bicycle simulator based on UC-win/Road
Background

Operation method of the bicycle simulator
1. Connect network & Turn on sensors

Cycling as a Means of Mobility
Rising bicycle mode share in response to modern city
issues.

traffic jams, land use, energy consumption, airpollution, climate change, physical inactivity...

Turn on the router, four sensors and PC
Make sure the router and the sensors are connected to one
router (Same IP address)

2. Open the scripts (Delphi)

Increasing Traffic Conflicts
Growing number of vehicles on the roads leading tomore traffic conflicts between cyclists and vehicles.

Open and run the delphi script BikeControlPluginMain.pas”

WHO report shows that pedestrians, cyclists, andmotorcyclists account for more than half of global roadtraffic deaths.

3. Evoke UC-win/Road

Understanding cyclists’ behavior in different design contexts is crucial for improving bicycle safety.
To understand cyclists’ behavior in different contextual settings, we developed a bicycle simulator.

4. Connecting sensors

It can help to:
1. Develop robust cyclist-focused datasets
2. Model bicycle dynamics
3. Evaluation of cyclists’ behavior
4. Study the environmental determinants of cyclists’ behavior.

By using a bicycle simulator, users can ride in a virtual scene by riding in place andimplement the following operations.
The bicycle simulator consists of simulation software and plug-ins (UC-win/Road 15.1),
a bicycle, a wireless router, four data sensors, and an image display screen.
Data sensors (Bicycle: Mormanton iThink Neway 7.0 RD folding bike)

1. Rear brake sensor

Brake data of rear wheel

2. Angle sensor

Direction data

UC-win/Road 15.1 will automatically open
Select the scene file, and load the simulated road scene.
The sensor data will be transmitted to the UC-win/Road
Click on the "SDK Plug-in"
Select "Bike Control"
Check the sensor connection status

5. Start riding

3. Front brake sensor Brake data of front wheel

Millan KS8 miniature built-in spring self-reducing displacement sensor

4. Speed sensor

The subjects began to ride, and could try steering, U-turn,accelerating, sliding, braking and other actions.
The simulator will simulate the real riding action in terms ofvision and body sense.

Advantages of the bicycle simulator
Immersive cycling experience

Customized virtual scenes✓ Realistic sight✓ Vivid sound✓ Motion sense✓ Simulate different road traffic environment(Traffic scenes, weather, day/night )User-friendly and Interesting

Convenient data output✓ High operability,✓ Wide application scenes✓ Low cost of use✓ Collect and output motion information
at different times(Speed, direction, position)

Future work

System Flow
1. Users cycle to generate movement data
2. Sensors collect data
3. The sensors are connected to UC-win/Road 15.1 through the User Datagram Protocol (UDP).
4. UC-win/Road 15.1 uses the bicycle control plug-in to control the bicycle movement in the virtual scene.

Connection to VR devices
Obtaining a more immersive bicycle riding experience in virtual scenes.
Capturing the experimenter's eye tracking data, allowing for a deeper study of rider behavior.

Experiments in the field of traffic safety researchExperiments on interactions and conflicts between road traffic participants can be designed andcarried out, which is considered expensive and risky in field research.

Developing cluster systems
Plug-inThrough an online platform, multiple experimenters can interact in the same traffic scene. Moreapplications, such as driver loop research, automatic driving algorithm simulation test, roadcollaboration/intelligent network vehicle simulation test would be supported.
