Parking guidance and information
Encyclopedia
Parking guidance and information (PGI) systems, or car park guidance systems, present drivers with dynamic information on parking
within controlled areas. The systems combine traffic monitoring, communication, processing and variable message sign
technologies to provide the service. PGI systems are a product of the worldwide initiative for the development of intelligent transportation system
in urban areas. PGI systems can assist in the development of safe, efficient and environmentally friendly transportation network .
PGI systems are designed to aid the in the search for vacant parking spaces by directing drivers to car parks where occupancy levels are low. The objective is to reduce search time, which in turn reduces congestion
on the surrounding roads for other traffic
with related benefits to air pollution
with the ultimate aim of enhancement of the urban area.

Traffic congestion
Traffic congestion is a condition on road networks that occurs as use increases, and is characterized by slower speeds, longer trip times, and increased vehicular queueing. The most common example is the physical use of roads by vehicles. When traffic demand is great enough that the interaction...
