Case Studies

Case 16: Wakefield City Center Bus gate system

Increasing traffic congestion in towns and cities offers great potential for buses to improve the mobility of travellers without increasing traffic. A package of measures on defined bus routes, including bus gates, bus priority and special bus lanes can serve to ensure free movement, particularly at peak times.

Case 15: New Hampshire DoT (NHDoT) - ORT (Open Road Tolling)

The New Hampshire Department of Transportation (NHDOT) selected Telvent to install their first open road tolling facility at their largest toll plaza in Hampton NH on I-95.  This case study gives an overview of the project and shows how Idris is part of the ORT solution.

Case 14: TESS Digital Capture Unit

TESS is a digital automated monitoring and enforcement company with facilities in both Australia and Malaysia.  Their product lines are based around two core products, TESS Digital Capture Unit and the TESS RFID Number Plate.

Case 13: Enhanced PIPS' SpikeHD camera

Becoming an Idris Technology Partner recently enabled PIPS to develop a new Idris-enhanced camera destined for the ITS market. The Idris software will reside on board the PIPS’ SpikeHD camera.

Case 12: All Electronic Toll Collection (AETC)

As a pioneering organisation, E-470 were one of the first authorities to implement open road tolling (ORT), and, in June 2006, they made the business decision to transition to an all electronic toll collection(AETC) system. E-470 were to take on another industry leading project and install cashless lanes.

Case 11: Tampa Expressway

The award winning reversible Tampa Expressway has revolutionised the journeys of thousands of commuters thanks to the advanced reversible open road tolling lanes provided by Peek Traffic USA and Idris AT600 tolling technology.  The project uses ORT with no toll booths or plazas which eliminates the risks associated with large volumes of traffic slowing down to pay the toll.

Case 10: Ministry of Transportation for Ontario (MTO) - Data Recording

The MTO had a requirement to purchase approximately 70 data recording units for the ongoing collection of traffic data. They were to be installed in a number of environments, from rural 2 lane roads to urban areas with densely populated traffic such as Toronto & Ottawa with up to 6 lanes of traffic. They needed a technology able to count and classify to greater than 95% accuracy levels and operate in all weather and traffic flow conditions.

Case 9: Exeter to Honiton - D.B.F.O (Design Build Finance & Operate)

The project objective was to provide reliable and accurate data recording technology with a user friendly interface for traffic monitoring on the A30, UK.  The bypass construction was intended to take the trunk road traffic out of the villages to ease congestion, which inturn, would enhance the environment and improve safety in these villages. The scheme would also provide additional capacity to improve traffic flow and help to accommodate future predicted traffic growth.

Case 8: North Texas Tollway Authority (NTTA) Express, Manual & ACM Tolling

In 2000 Idris was adopted as NTTA's standard Automatic Vehicle Classification system. NTTA implemented Idris into their express and mixed lanes using a boxed product. The system was installed onto two major toll highways and challenges during the implementation included new construction combined with retrofit of existing lanes.

Case 7: Dover Toll Plaza - AT700 Tolling

SR1 is not only a major thoroughfare north and south through the state of Delaware carrying considerable commercial traffic, but it is also located in a major agricultural area. Accordingly, many types of trailers are utilised, including goosenecks, and at peak times congestion does occur. Further, Delaware experiences a full scope of weather patterns ranging from snow and ice to blowing rain and fog. Any tolling solution considered needed to take into account and handle all these factors.

Case 6: First of Type for New Jersey Turnpike Authority

ACS State & Local Solutions (ACS) and the Idris Technology step up to the mark once again with the opening of a five-lane Open Road Tolling (ORT) plaza in the State of New Jersey. Early in May 2005 the plaza was successfully opened using the ACS developed and implemented “Vector Express Tolling Solution”. This is a purpose designed multi-lane ORT tolling solution which is supported by the Idris AVC and AVI correlation technology and Mark IV tag readers.

Case 5: Aberdeen - Vehicle Priority

One of the Idris technology applications is for Vehicle Priority, it is this application which Peek Traffic integrated into their own product - Prism. Using standard inground loops, the Idris technology is now increasingly seen as a data-profiling tool for the realtime management of traffic in a variety of situations, including bus priority.

Case 4: Biddles Corner - AT600 Express Tolling

In 1996, the Delaware Department of Toll Roads was looking for a classification system which could function at a high level of accuracy in high speed express ETC lanes. The first site was Biddles Corner, north of Dover on the SR1 (State Road 1) toll road. SR1 extends the length of Delaware and DelDoT needed to expand the capacity of the Biddles plaza to support the traffic growth. Increasing the number of lanes would have been difficult and expensive because of constrained right of way.  

Case 3: New Jersey Turnpike Authority & ACS

With 44,000 vehicles a day the Exit 1 tolling plaza on the New Jersey Turnpike is one of the busiest in the United States.  This project had a crucial criteria for the accurate detection and classification of vehicles using the express ETC lanes. There was also a later addition to the contract which included the provision of four open road tolling (ORT) lanes (two in each direction). The ORT system would need to be able to handle very high volumes of traffic traveling at 65 miles per hour.

Case 2: South Jersey Transportation Authority (SJTA) & Open Road Tolling (ORT)

This case study looks at SJTA's requirements for an ORT solution for two non-delineated travel lanes with vehicles traveling at highway speeds. SJTA required AVC and VES to work in conjunction with the Mark IV AVI subsystem to accurately determine, the correct toll for all vehicles utilising the lanes and, to capture images of all vehicles not bearing valid transponders. The decision was made to use Idris due to its capabilities within an ORT environment and proven track record.

Case 1: E-470 & Idris as the Automatic Vehicle Classification System

E-470 in Denver, Colorado is 47 miles long and runs from I25 South of Denver to the new international airport and beyond linking to I25 in the North.  When Plaza E was built, the decision was made to use Idris as the AVC system because of the following benefits:

• Auditing made easy with fewer exceptions to deal with;
• Ease of reviewing data;
• Elimination of light curtain maintenance costs;
• Elimination of treadle maintenance costs;
• Labour saving on cleaning of light curtain.
