Project title: BeTimes Project
Location: Beijing，China
Period: 2005
Client: Beijing Traffic Management Bureau

Abstract:
The system utilizes advanced traffic models, surveillance information, various historical data to provide graphic and dynamic traffic management functions. DSS is the key part of the project, which is for traffic control design, optimization, and dynamic traffic management (DTM) that is to provide network-wide dynamic traffic states and to propose a management scenario to a traffic problem such as congestion, incident or roadwork.

• Estimating and predicting (short-term) traffic bottleneck or event (accident, road work? etc.,)
• Providing traffic management measures corresponding to the event, and simulating it
• Evaluating the result of the simulation
• Saving the best scenario to the expert database for the future use

It is a knowledge-based expert system and a tool for the evaluation and analysis of the impact of each scenario. DSS Graphical User Interface (GUI) allows users to further customize specific scenarios to given problems. Effective scenarios are stored into a relational database and can be used offline or online.

Project title: TCSS-Hong Kong Airport
Location: Hong Kong
Period: 1997
Client: The Airport Authority, Hong Kong (Owner), G.E.C. (Hong Kong) Ltd. (Contractor)

Abstract:
Hong Kong is built almost entirely on reclaimed land off Lantau Island, and once was accessible by ferry only. To cater to vehicles arriving at this busy airport, an advanced Traffic Control and Surveillance System (TCSS) was needed as a key component of ground traffic operations. Using modern technologies and innovative concepts, DHV/Delcan developed a system that provides efficient traffic management and seamless operations.

Services

• Provision of traffic control and surveillance systems
• Detailed engineering and software design
• System integration and implementation, testing and training

The Hong Kong Airport Traffic Control and Surveillance System project was winner of the 2000 International Road Federation Global Achievement Award and recipient of a 2001 Award of Excellence from the Association of Canadian Consulting Engineers.

Project title: CTCS-Vancouver, BC
Location: Vancouver, British Columbia
Client: The City of Vancouver

Abstract:
The City of Vancouver’s existing traffic signal management system (600 signals) was originally installed in the mid-1980s. System capacity, aging equipment, lack of spare parts and an impending Year 2000 compliance problem required the City to replace their system.

The City retained DHV/Delcan as System Manager for implementation of the central traffic control system (CTCS). As System Manager, DHV/Delcan’s responsibilities included:

• Overall design and identification of system requirements including central hardware, field controllers, LAN, CCTV, internet connections, etc.
• Development of technical specifications for central hardware, third party software, field controllers, etc.
• Design and development of a communications protocol for implementation;
• Adaptation of a central software package to meet the citys' requirements;
• Design of a system transition plan to minimize system downtime;
• System integration; and
• System documentation and training.

The system has allowed the City of Vancouver to expand the capacity of their signal system while maintaining use of existing City-owned communications system. It has also provided the City the flexibility to maintain the use of their current controller inventory while providing them the option of expanding their system in the future through an open controller procurement process.

Project name: Tianjin Railway Station

Abstract:
Tianjin has the dual distinction of the being the 4th largest city in China as well as the port city of the capital Beijing. Within the next two years a new high speed intercity railway will connect Tianjin to Beijing reducing the commute from 2.5 to 1 hour. This is a critical link for this burgeoning satellite city.

In January 2006, DHV allied with de Architekten Cie to participate in a competition for a comprehensive master plan and architectural design of the Tianjin central stations.

The project includes the complete design of the underground infrastructure, 4 landscape squares, the intercity railway station, the metro/long distance bus station, local bus station, old train station renovation, baggage building renovation, and a new parking building.
