Congestion can also happen due to non-recurring highway incidents, such as a crash or roadworks, which may reduce the road's capacity below normal levels. Cleary, N. Worthington Eyre, H and Doonan, K. 2010. Fortunately, not all of the effects are negative. (2019, February 14).

Reed, S. (2018, September 21). For example, a flexible workplaces pilot was undertaken in Brisbane, Australia during 2009 to test the applicability of a voluntary travel behaviour change program to achieve transport system outcomes, particularly as they related to managing congestion, either through mode shift or peak spreading.
