AOL Anywhere COMBITECH TRAFFIC SYSTEMS - TOLL COLLECTION SOLUTIONS Combitech Traffic Systems is dedicated to supplying toll highway operators with systems and products for efficient, convenient and accurate electronic toll collection (ETC). The company's products and services are based on its own leading knowledge in image processing microwave technology and application know-how. The company works in basically two segments of the market: Supply of a microwave based communication link for upgrading of traditional, single lane toll systems to Electronic Toll Collection (ETC). The innovative electronic toll systems are marketed under the brand name PREMID® and are already in use in 17 countries worldwide. With present installations and orders, over 2.5 million drivers are able to enjoy paying tolls electronically in more than 2000 toll lanes equipped with PREMID® technology Supply of turn-key systems (TOLLMATIC®) for state-of-the-art Multi Lane Free Flow tolling systems such as the Melbourne City Link and Single Lane systems such as the SPRINT Highway tolling system in Malaysia PREMID® TRANSPONDER AND TRANSCEIVER The PREMID® transponder is attached to the vehicle’s windscreen. It contains information about the vehicle and the relevant account. The PREMID® transceiver "reads" the transponder and its information about items such as vehicle classification and mode of payment. Communication between the roadside and vehicle occurs across a 5.8GHz PREMID® DSRC microwave link that complies with the European Committee for Standardisation (CEN) standard. VDC AND VR SENSORS The VDC sensor consists of two wide-angle cameras that classify vehicles using a stereoscopic image. Thanks to our proprietary stereo recording technology, the vehicle classification (based on measurable vehicle dimensions) can be determined at speeds up to 160km/h (100mph) regardless of vehicle lateral placement on the road. This is done without affecting traffic flow or causing congestion. The VR sensor consists of two video cameras with an infrared flash, used to record vehicle license plates. THE PREMID® TS3200 DSRC (DEDICATED SHORT RANGE COMMUNICATION) LINK This system is the communication link between the vehicle and roadside. It is designed to provide optimal performance, both with traditional single lane systems and with toll road systems based on multi-lane free flow. The specification complies with CEN TC278. This brings you as an operator several advantages. Transactions are very secure, for example, and the open architecture means that you have the option of choosing between multiple competing suppliers. TOLLMATIC® SINGLE LANE This configuration is often used when upgrading an existing manned toll plaza. Vehicles pass, just like in a traditional system, in clearly designated lanes. Each lane constitutes its own communication zone, controlled by a transceiver. When the vehicle passes through the zone, the transceiver reads the vehicle’s ID. Reduced speed is usually recommended for safety reasons. There are two ways to handle violators: either using traditional barriers, or via video enforcement. The latter uses a video recording that records the vehicle’s license plate. In this case, the driver can be charged after the event. When used this way, TOLLMATIC® works automatically, creating a free flow system. When an existing manned toll station is going to be adapted to electronic toll collection, a single lane configuration is usually the first step. TOLLMATIC® MULTI LANE When the objective is eliminating bottlenecks – i.e. at approaches to tunnels, bridges, beltways or freeways – a multiple lane system usually works best. Since the gantry occupies no more space than the roadbed itself, a multi-lane system is usually the best alternative for construction of a new toll payment area on either a new or existing road. Identification, classification and enforcement, all take place in a fraction of a second – regardless of how many vehicles are located within the section of road and regardless of their lateral position on the road. Combitech Traffic Systems is one of the driving forces within DSRC standardization and one of the co-designers of GSS (Global Specification for Short-range communication) and the A1 specification. Both these specifications are assisting operators in the process towards a situation of multi-sourcing in supply of DSRC equipment as well as interoperability between different operators. The company has 85 employees, most of the highly educated engineers, and a turnover in the range of 40 MUSD. [ Next Thread | Previous Thread | Next Message | Previous Message ] |
