Shadow Tolling - DBFO Schemes
Golden River is a world leader in shadow toll schemes.
With 14 years experience in the configuration, installation, maintenance and verification of traffic data for shadow toll schemes, Golden River operate over 240 outstations covering more than 400 kilometres of major roads. These schemes are both accurate and reliable with an unrivalled performance of greater than 99% up time including accounting for damage to equipment and road closures.
We understand the requirements of road operators and contractors for reliable traffic monitoring equipment to guarantee regular payment of shadow tolls. Missed data means lost revenue, Golden River has an unrivialled, proven track record fulfiling this need.
The shadow toll, also known in the UK as Design, Build, Finance and Operate (DBFO), concept started life as a precursor and transition to full motorway tolling, designed to create a private-sector road-operating industry assuming responsibility for the operation and maintenance of a length of new or existing roads (where appropriate) and for building specified improvement schemes.
The principal benefit lies in the increased value for money to the road authority / taxpayer of procuring a road service in this way. This is achieved through a combination of transfer of risk and the introduction of private-sector innovations. Construction is accelerated over traditional road building schemes so that the operator can achieve an early return on the investment, and do not discourage migration to the new road where there are competing alternative non toll routes.
Golden River is at the forefront in the design, installation and management of the traffic data collection systems that form the heart of the payment systems of the schemes.
Payment schemes are based on the number and type of vehicles using the road. These can be refined with penalties on average speeds falling below a pre set average, and adjustments made for lane closure and safety performance. These are shadow tolls as opposed to real tolls, as payment for usage is made by the road authority rather than by the road user.
Golden River’s technology provides the vehicle count, vehicle length and classification data via the use of the highly accurate and reliable Marksman range, communications and outstations. Our experience covers a range of different payment schemes from basic shadow tolling to the more complex Active Management Payment Mechanism type schemes. Where applicable contracts have also included regular video verification of collected data.
- Two, three or four lane; and hard shoulder, motorway monitoring via outstations
- Highly accurate speed and length measurement using the Golden River Marksman 72X.
- Real time journey time measurement to better than ± 1%
- Enhanced reliability through SPC (Statistical Process Control)
- Automatic base data collection for length/count verifications
- Unique (patented) speed accuracy verification using a highly accurate vehicle mounted GPS system connected to a site database.
- Speed, Length and arrival time of each vehicle is stored at the outstations and collected at pre set intervals.
- One cabinet for CMPs (count measurement point, including video verification gear, but no ANPR). Second cabinet for SMPs (speed measurement point, ANPR)
- Integration of loop technology for vehicle count/length and ANPR for speed.
- Collection of verification base data and video locally for both count/length and ANPR verifications.
- Automatic validation achieved by
- traffic anomaly recognition
- loop performance monitoring
- Vehicle processing performance.
- Development of a journey time engine to calculate average journey time using ANPR.
- Reporting Software
- E-Mail / SMS for fault management. Outstations automatically send fault data back to the Instation in real time.
