POSITIONING, MAPS & LOCAL REFERENCING

In order to support the advanced applications proposed in CVIS, there is a need to develop novel positioning and mapping solutions. POMA intends to develop those new solutions while taking advantage of new communication and cooperation schemas offered by CVIS.

Objectives

Within the CVIS Integrated Project, the POMA subproject will research, develop, test and validate advanced mapping and positioning solutions. POMA is to provide a set of positioning and mapping services that will run across CVIS entities (vehicle, roadside equipment, service center, etc.).

Furthermore, POMA will integrate different positioning techniques, including infrastructure-based positioning, and provide integrity indicators on resulting positions. Regarding mapping, POMA will include new map content, support the distribution and integration of map updates, and support sharing of geo-referenced content across CVIS entities.

Challenges

POMA focuses on the following challenges:

Going beyond current solutions in positioning and mapping
Providing cost-effective and reliable positioning solutions
Integrating on-board sensors and in-road sensors
Enhancing current map solutions
Providing framework to create micro-level, highly dynamic, traffic maps
Formulating confidence levels of the measures
Transmitting data efficiently to minimize network loading
Implementing POMA interface within CVIS applications (CURB, CINT, CFF, COMO)
Implementing POMA solutions in existing vehicle or roadside environment.

Results

There are numerous results expected from POMA within the CVIS project and the external community.

POMA positioning modules ready for implementation in the vehicle or at the roadside level
POMA mapping and map matching solutions ready for implementation by CVIS applications
Interface to exchange geo-referenced content
Provision of POMA for CVIS applications' test sites
Contribution to standardization in the field of mapping and positioning

Technologies and key concepts

Key technologies addressed by POMA are:

Positioning modules integrating different technologies (GPS, EGNOS, inertial sensors, RF signal triangulation, etc.)
Indicator of overall integrity/robustness (providing error range and level of confidence) to describe resulting pose (position and heading)
Map modules offering enhanced map content, map access APIs and map update mechanism
Enhanced map-matching solutions able to compute lateral distance to the centre of the road
‘Basic technologies’ like location referencing, based on AGORA-C, and geo-referencing language for data exchange between the different CVIS entities
