Land Transport Service Delivery at WMO: Summary of a WMO ad hoc working group meeting -- 28 January 2015

Dr Walter DABBERTVaisala Group

Why Land Transport Service Delivery?• Land transport service delivery is already an important NMHS

function in many countries• Land transport service delivery is a present and emerging need in

many other NMHS' s• LTSD includes, broadly, roads, rail, rivers, harbors, lakes, and

airports; roads and rail shared many commonalities and represent a good starting place for LTSD

• Land transport service delivery is a high priority function as it involves:• Public safety, and • Significant societal and economic benefits (and risks)

• LTSD is a natural extension of WMO service delivery efforts that currently include aviation and marine transport

• LTSD includes many functions in the transport value chain, which currently are provided by a mix of governmental and private-sector organizations, where this mix varies significantly from country to country as well as within individual countries; as such, WMO leadership would serve the members well.

Simplified Value Chain• Observations

• Meteorological• Geophysical• Traffic

• Modeling• Mesoscale NWP• Microscale energy balance & nowcasting• Traffic flow

• Analysis & Forecasting• Mitigation Options Assessment

• Roads & rail treatment• Traffic adjustment

• Decision-making, Implementation & Communication• (where value is created)

Users

• End users• General public• Railroad companies• Trucking companies• Bus companies• Taxi services• Freight forwarders• Transport hubs• Public safety organizations• Emergency managers

• Intermediate users• Road authorities• Local governments

Providers• NMHS's

• Meteorological observation data• Road weather & state data• NWP • Nowcasts

• Road authorities • Road state data• Traffic data• Road weather data• Vehicle weather-related data

• Private weather companies• Road & rail weather data• Road & rail state data• NWP• Nowcasts

• Private data companies • Mobile phone-derived data

• Traffic speed & volume• Atmospheric pressure data

WMO Roles (present & future)

• Meteorological observation standards/requirements• Station siting• Observation requirements and methods• Instrument standards• QA/QC requirements• Metadata requirements

• Best practices specification (e.g.)• Surface energy balance • Inter-station interpolation

• Data format standards• Data sharing and integration• Training
