The project is about a pedestrian and bicycle bridge with pavement system could tracing movement of walkers and cyclers. Inspired by idea of Social computing, which is an area of computer science that is concerned with the intersection of social behavior and computational systems, the bridge designer apply mobile application as remote control, simulating the movement of humans on the bridge.
The bridge has two part separately, could be mainly used for pedestrians and bikers. The linkage between the two parts improve flexibility on choosing direction, and reinforce the structure with wires as well.
Pedestrian Tracing Pavement
The experimental model was created with Rhino-grasshopper and remote control device, which simulate the situation when users are walking on the bridge. The more walkers get together, the more colorful the pavement could be.

Bicycle Tracing Pavement
The model provides a function of tracing the moving path of bikes, and gives instantaneous velocity and curvature at certain points.

Remote Control
1 Install mobile application and choose interface as need.2 Set the Mobile in the same IP address and port data with PC .
