Objectives

The ProbeIT objective was to develop a process (end-to-end) for the sourcing and exchange of position-related information between

traffic management systemsa uniform data sourcevehicles

The aim was to provide timely and accurate location based information in the vehicle using a telematic link to enable NextGeneration Advanced Driver Assistance Systems (ADAS).

Three phasesnon-dynamic data flowdynamic data flowfloating vehicle application

Phase 1

Non-dynamic data flowdigital maps for navigation –underlying map data

Phase 2

Dynamic data flow‘static’ speed limits and parking restrictionsdynamic navigationreal-time variable speed limit informationreal-time traffic information

Phase 3

Advanced probe vehicle informationroadworksairbag alert

?

(proved but not fully integrated during project)

Framework design

ProbeIT open architecture model

Achievements: Acquisition of static information

Speed limits and waiting restrictions in EssexLocation referencing depends on format

Road centrelines for speed limits – use road name and end pointsZones for parking restrictions –find intersections between zone and ProbeIT segments

Match location to ProbeIT databaseSpecify information type

Further Work

National speed limit database (SLD)Atkins performed feasibility study for DfTvery positive business casewide support for database and in-vehicle speed limit informationDfT ITS policy framework – considering options for SLD and also Road Information Framework (RIF)

Possibility for links between ProbeIT concept andISACVHS RUClocation-related vehicle safety applications

Further Work

In-vehicle systems will be available within 3-5 years assuming the data is availableMany manufacturers and map providers are interested
