Summary
As part of the Bus Information and Signalling (BIAS) project, we have delivered the Integrated Management Facility (IMF), based on our Common Data Management Facility. The IMF is the core of the BIAS system, providing a single central management mechanism, integrating new and existing systems, and providing a common operator interface to reduce operator load and resource demands within the traffic control centre.
Integrated Fault Management provides streamlined processing of faults, offering automatic relay to maintenance contractors and including automatic acceptance from native systems. The integrated Asset Management function provides flexible administration of site inventory.
The Strategy Integrator function analyses data such as events, congestion and bus link journey times to alert the operator to abnormal conditions. The system can then propose pre-prepared responses to resolve network problems.
CDMF also forms the heart of a city-wide car park guidance system integrating live car park occupancy feeds, with information displayed on VMS at key locations. Gateway VMS are also controlled from the system.
BIAS serves a number of stakeholders in addition to Glasgow City Council, including West Dunbartonshire Council and First Glasgow providing these partners with a comprehensive overview of network conditions, allowing better multi-modal network monitoring and management.
Key Features
The Integrated Management Facility delivered by Mott MacDonald is at the heart of BIAS providing a Common Information Base, a Common Graphical User Interface, a strategy integrator application and a performance evaluation application. Fully integrated Fault Management and Asset Managemant capabilities are also provided.
- The User interface provides the standard easy to use CDMF Viewer with map and gazetteer to help users locate events and equipment. There is a more extensive display of field equipment with zoom levels extending down to kerb line detail.
- A fully integrated Fault Management system provides facilities for notifying and for clearing faults. Maintenance Contractors access the system remotely from their maintenance depot and notify when faults are fixed. The system includes administration facilities for maintenance contracts, as well as automatic acceptance of faults from all connected systems.
- Asset management, providing an easy-to-use interface for operators to maintain site inventory information, with geo-located placement of equipment.
- The Strategy Integrator function is designed to provide a more reactive response to events. Events are detected automatically using a fusion of data sources for a given area of the street network and for known problems. The Strategy Integrator allows responses to be sent to both old and new UTC systems, as well as providing CVMS setting capability.
- Performance evaluation is provided by means of reports generated using a Crystal Reports package, integrated with CDMF. This facility reports on the level of service to Public Transport vehicles by the BIAS UTC and evaluates and monitors the benefits being provided to public Transport. It also reports on the level of service achieved form the various types of equipment through analysis of the fault records. Reports cover the range of statistics concerning the fault rate and availability of equipment and monitor the operational performance of equipment and highlight any change in trends.
- An intelligent interface to Strathclyde Fire and Rescue's Greenwave system co-ordinates emergency services Greenwaves across two UTC systems
- The system is deployed on a replicated hardware architecture with standby application and database servers. In the event of hardware failure, the appropriate standby machine can be brought online within minutes.
System Architecture
The GCC CDMF enables the following new and legacy systems to be integrated:
- The new Vehicle Actuated Traffic Control (VATC) and Remote Monitoring System from Peek Traffic Systems. Data transfer across the interface uses standard UTMC data objects, providing controller status/fault information and congestion/flow data. The interface also supports the invoking of command messages, to bring up views of UTC and to provide a number of integrated UTC commands from the CGUI.
- The Automatic Vehicle Location (AVL) and Real Time Passenger Information (RTPI) being supplied by Serco with AIM, with an adapter providing fault and alert information.
- The existing UTC system, CITRAC2, for Glasgow. This fixed time UTC was supplied in the early 1980s. An adapter has been designed and implemented that transfers data on status fault, alarms and alerts and allows the invocation of command messages.
- Emergency Vehicle Priority notifies both UTC systems which operate in a coordinated fashion to deliver green waves.
- A number of car parks management systems are being integrated. These include ZEAG and SkiData systems.
The Glasgow CC CDMF is also providing a highly integrated operator display, based on the Common Data Viewer (CDV), giving access to both a fully integrated “operational” view of the City’s traffic and travel information systems together with direct access, from the same operator workstation, to the configuration screens of the sub-systems.
