The CSE Intelligent Transport Systems (CSE - ITS) group has expertise in project management and experience to offer and deliver cost effective integrated solutions to the satisfaction of our clients. Based on our innovative strength and IT expertise, we are able to offer innovative and efficient products, systems and services for every aspect of ITS Industry.
We were part of the international consortium that developed the technology behind the world’s first free-flow multi-lane (FFML) Electronic Road Pricing (ERP) system for the Singapore Government. The multi-million dollar ERP system was successfully commissioned in 1998 and we are presently responsible for maintenance and routine upgrading of the system. As pioneers of Intelligent Transport Systems, we are leveraging on our strong domain knowledge to helping other governments in the region.
Our services/solutions for ITS include:
Electronic Road Pricing
Electronic Road Pricing (ERP) is an electronic system of road pricing. This road pricing system is based on a pay-as-you-use principle. It is designed to be a fair system as motorists are charged when they use the road during peak hours.
It uses a dedicated short-range radio communication (DSRC) system to deduct ERP charges from the pre-paid cards (CashCards). These are inserted in the In-vehicle Units (IUs) installed at the back of the windscreen of the vehicles before each journey. Each time they pass through a gantry when the system is in operation, charges are deducted.
The pay-as-you-use principle of ERP makes motorists more aware of the true cost of driving. This way, road usage can be optimised.
- Charges are levied on a per-pass basis and rates are set based on traffic congestion level at the pricing points.
- A motorist is encouraged to decide whether to drive, when to drive and where to drive.
- He may choose a different route, destination, time of travel, or not to travel at all.
- He may decide to car-pool or use public transport.
- Those who choose to pay and stay on the road will enjoy a smoother ride.
Electronic Toll Collection System
Electronic Toll Collection (ETC) system has been seen as an effective way to finance new infrastructure and improve traffic flow. ETC can also save road travelers time and frustration, allowing them to drive non-stop through tolling area. When a car passes through a toll point, a roadside antenna reads a small electronic transponder (On Board Unit - OBU) which is installed inside the car’s dashboard or behind the car’s windscreen. Vehicles are billed automatically as they pass through the tolling area, improving throughput and minimizing delay.
Several technological approaches are available:
- Electronic Tolling systems are used extensively overseas. The DSRC system utilizes a small electronic transponder (On Board Unit – OBU) together with gantry-mounted reader which either deducts the charge from the electronic transponder or the pre-paid cards inserted in the transponder or add the toll charge to the vehicle owner account. Enforcement is via automatic vehicle number plate recognition cameras.
- Video-based system relies exclusively on automatic number plate recognition cameras. The images are checked against a database to verify payment or eligibility for discount or exemptions.
Communication Backbone Systems
Keeping tabs on statewide, regional and municipal traffic activity is a task that requires a large and diverse telecommunications network infrastructure. A well designed network can satisfy continually evolving needs for real-time combined video, voice and data communications between municipal, county and state locations. This entails, among other challenges, integrating a wide variety and vintage of electronic equipment having different communication protocols from PCs, to traffic control equipment, to video cameras.
For optical transport of ITS applications such as video surveillance, toll collection, traffic monitoring and control, VMS, emergency voice, signaling and loop detection, JungleMUX SONET, TN1U SDH and TN1Ue SDH multiplexers are the ideal optical communication solutions.
Urban Traffic Control System
Traffic signal control system in cities that automatically adjust themselves to optimize traffic flow, giving right-of-way to public transport.
Operates in real-time, it determines the most appropriate timing for the green lights at an intersection so that successive intersections are linked to allow maximum efficiency for the circulation of the flow of vehicles.
Electronic Information Display System
The Variable Message Sign (VMS) is increasingly being used to provide drivers with advance information of road conditions ahead and can be applied to both expressway and urban road networks.
In Motorway Management System (MMS), VMS signs have an increasing function in motorway traffic control by delivering such benefits through its solutions-based approach to the needs of specific road and traffic situations. The benefits of this real time information are to reduce speed, avoid congestion, choose another route and lessen driver frustration.
Light Emitting Diode (LED) display signs direct millions of travelers each day with timely, accurate and useful traffic information. It come with various sizes to fit a variety of traffic management applications, such as display motorists information, incident management, airport flight and parking information, bridge, tunnel, toll road traffic control etc. LED signs become an integral part of many Intelligent Transport System (ITS) programs. LED displays are growing in popularity because of their low power use and low maintenance costs.
Motorway and Tunnel Management System
Motorway and Tunnel Management systems (MTMS) providing information to motorists, recommending optimum speed for instance, thus increasing capacity and flow, and minimizing congestion due to accidents.
Tunnels introduce unique traffic safety considerations and tunnel control system evaluates and processes most eventualities from accidents, fire and congestion to maintenance activities, implementing land flow changes from local control centers. When accidents are detected, automatic functions intervene immediately.
Traffic Data Collection
Fully programmable Traffic data logger provides count and vehicle classification up to eight, high flow un-directional or bi-directional lanes of traffic Data collected can be retrieved via laptop or over telemetry.
Traffic counter/classifier is to provide accurate and dependable data for road Traffic Information System.
Over-height Vehicle Detection systems
Over-height Vehicle Detection Systems (OVDS) are warning devices which designed to alert drivers if their vehicles are over-height for an upcoming bridge, overpass, overhead walkway, etc. and make them take actions that eliminate damage to their vehicles and the structure ahead.
The system works by installing infrared beam from the transmitter to the receiver, placed directly across the lane or lanes of traffic to be monitored and an inductive loop to detect presence of vehicle in advance of the warning sign. Once the system detects an over-height vehicle by the breaking of the infrared beam, the system will activate the warning signs to instruct the driver of the best way to avoid the collision.
Online Traffic Information System
This system uses cellular networks to detect and deliver traffic data to Traffic Authority or Highway Authority. It captures cellular signal and models road traffic. The solution calculates system-wide speed and travel times in the coverage area on a regular interval.
This data enables transportation agencies to better manage and re-direct traffic, detect and respond to incidents, and plan for and design new roads.
Traffic Signal Lantern
We are able to offer a wide range of traffic signal solution to meet all control situation
Several type of optics are available:
- Bulb technology: Halogen and incandescent
- LED technology
Traffic signal lantern diameter: 100mm, 210mm and 300mm
Pedestrian Countdown Display
The pedestrian countdown display is installed and used together with traffic lanterns in order to increase the level of safety for road users.
This display gives pedestrian more information and hence greater control over their crossing decision. It was also observed that there were fewer incidents of pedestrian attempting to cross the road towards the end of the ‘green time” cycle, as they were able to judge from the countdown display facility if they had sufficient time to cross the road safely.
