automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. most of the road detection approaches are based on image segmentation algorithms. color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. in order to reduce the light change ...

Recently, Cellular Automata (CA) models are developed and studied mostly for homogeneous traffic flow. In the current paper an attempt has been made to use CA models to study heterogeneous traffic flows which are common in real life situation. For a better representation of different types of vehicles, cell sizes have been reduced. A different set of CA rules to control the light and heavy vehi...
