shick waves in traffic streams

Shock Waves in Traffic Streams
Sudden fluctuations in the traffic stream,
Spatial changes
Temporal changes


With such changes, the condition of the traffic will also
change from one state to another

,Shock Waves in Traffic Streams
This describes the phenomenon of backups and queuing
on a highway due to a sudden reduction of the capacity o
the highway (known as a bottleneck condition)
The sudden reduction in capacity could be due to a crash,
reduction in the number of lanes, restricted bridge sizes,
work zones, a signal turning red, and so forth

, Types of Shock Waves
Frontal stationary shock waves are formed when the
capacity suddenly reduces to zero at an approach or set o
lanes having the red indication at a signalized intersection
or when a highway is completely closed because of a
serious incident
