Analysis of traffic flow control results under accidental accidents.

Analysis of controlling efficiency	Situation
	Lane 2 is occupied	Lane 3 is occupied	Lanes 2 and 3 are occupied
Flow restriction rate	−70.29%	−64.43%	−91.44%
Road capacity without controlling	1463.39	1554.32	374.12
Road capacity with controlling	1627.55	1776.22	394.75
Efficiency of flow controlling	11.22%	14.28%	5.51%
