Driving Risk Analysis Based on Driving Experience at Hook-Turn Intersection Using the Emerging Virtual Reality Technology

Algorithm 1

(1)	Postpone executing the code until Vissim runs.
(2)	Retrieve Vissim signal head data(i)Find the ID number which is assigned to the traffic signal model(ii)Put the traffic signal model information into the traffic signal 3D model in Unity3D
(3)	Check the Vissim signal status every single frame(i)Check the status of the Vissim signal(ii)Change the color of the signal head in Unity3D accordingly
