Tactic of Manipulate people

Traffic Light Rush

In nowdays people like to cross road during the red traffic light
but what happen if a car sudden appear or the person next to you suddenly run?

Idea 1
so my idea was cross the road during red light with the victim of this test, then on the half way, i'll just run like there is a car rushing in. If it working the other people that cross the road will also run.

Idea 2

Install a speaker near the traffic light, then cover it boxes
the speaker are installed with a hard brake sound effect that'll be triggered by remote control.
so when people cross during the red light, then we'll triggered sound effect.

Conclusion 
The idea was Manipulate people by their sense of hearing and sight.
