Details

The Service Interface for Real-time Information Vehicle Monitoring (SIRI-VM) standard is designed to:

• exchange vehicle monitoring information between control systems
• distribute this information to journey planners, alert systems and displays that wish to process and match real-time positions based on structured elements

SIRI-VM provides information about the current location and expected activities of public transport vehicles including:

• current and subsequent journeys
• the calling points on each journey
• the scheduled and expected arrival times

This technical guidance provides an insight into the parts of the SIRI-VM standard that will be captured via the Bus Open Data Service. It is aimed principally at system architects and designers who have a basic understanding of:

• SIRI (CEN EN15531)

• other UK and CEN public transport data standards such as Transmodel (EN 12986), NeTEx (CEN TS16614), NaPTAN and TransXChange
