Traffic congestion in the Airport
Reduce in regional economic health. Delays resulting in lost business , personal losses etc…
(late arrivals). Inability to forecast travel time accurately. wasted fuel increases air pollution & co2 emission which
contribute Global warming
Frequent repairs & replacements of vehicles.Causing health problems in motorists….[stress,
frustration ]. Emergency vehicles may be blocked. “ rat running”( affects the neighborhood amenity) .
Main solution for controlling traffic congestion is
Congestion pricing
Congestion pricing or congestion charge is a system of Surcharging users of transport network in periods of peak Demand to reduce traffic congestion……
Cordon area pricing: charges for passing the cordon line around a city center.
Area wide pricing: charges for being inside an area.
Toll ring pricing: Toll collection surrounding the city.
Corridor pricing : Access to a lane is priced.
OBJECTIVE :To make users more aware of the costs that they impose upon one another when consuming during the peak demand, and that they should pay for the additional congestion they create.i.e. when demand exceeds supply…….
Congestion pricing is widely used by telephone and electric utilities, metros,railways & auto bus services.
Critics maintain that congestion pricing is not equitable, places an economic burden on neighboring communities, has a negative effect on retail businesses and on economic activity in general, and is just another tax.
street markings and a sign (inset) with the white-on-red C alert drivers to the congestion charge.
A system that enables settlement of parking fees without parking Tickets and cash.
IU-> in-vehicle unit.CHU->charging unit.
More than 99% of vehicles in Singapore are equipped with IU’s.Toll fee is collected into the IU’s using RF communication from IC cards.

Types of Electronic parking system
Traffic decreased by about 13% during ERP operational hours.
Vehicles decreasing from 270,000 to 235,000.
Carpooling has increased.Average road speeds increased by about
20%.
Traffic estimation & prediction system
This new system integrates with existing systems like
Green link determining system (GLIDE).Traffic scan.Expressway Monitoring Advisory system(EMAS).Junction Electronic Eyes (J-Eyes).Electronic road pricing (ERP).
This system is designed
To allow variable pricing.Improved overall Traffic management.Alert drivers about conditions ahead.Charging the prices at the moment.
Trial results:Accuracy more than 85%.Predictions up to 60 minutes
