SINTECH Local Dynamic Maps - Scenarios

• A real time updatable Local Dynamic Map is
  defined as
• Integration of standard digital maps with dynamic
  (short time) and local (short range) layers of
  information collected by the infrastructure or by
  the vehicles (road status, obstacle presence,
  etc.).
• Focus on new contents and information that is
  provided in real-time
• need of high efficiency algorithms
• definition of an adaptive optimal coverage range
• compatibility with standard digital maps
• The main target is to provide a representation
  of vehicles and infrastructure surroundings with
  all static and dynamic safety relevant elements
• The local dynamic map model relies on the notion
  of a perception area (i.e. the coverage area of
  the ego-vehicle perception) and comprises at
  least
• surrounding objects, such as vehicles, obstacles
  and landmarks, e.g. in terms of relative
  positions, estimated dynamic states and
  attributes as well as associated confidence
  measures,
• road segments, e.g. in terms of geometrical
  parameters and attributes (road state, width
  etc.)
• traffic information/status for individual road
  segments or regions of the map
• weather or visibility status for individual road
  segments or regions of the map
• Open question What about trajectories?

SINTECH Local Dynamic Map interfaces to SP4/SP5
applications

• SP4 / SP5 applications clients
• Interface towards the Local Dynamic Map to get
  data no editing function?

• Brokers
• cast requests into queries and subscriptions to
  notifications
• select/filter data
• translate messages,notifications
• remote procedure calls over platform network

SINTECH Local Dynamic Map interfaces to sensing
systems

• Local Dynamic Map APIs
• towards the Data Fusion
• and Database Surveillance
• T-API (transaction) to edit the Local Dynamic Map
• Q-API (query) to get information
• The door is still left open to
• exchange raw data information
• between the systems.
• The transaction call handling and
• generation is done by brokers.
• There is a specific component for
• data that shall be distributed.

SINTECH Local Dynamic Map architecture proposal
and role in SAFESPOT

• Local Dynamic Map Component
• Separates the applications from the data fusion
  and object surveillance functions
• Provides a standardized access of real time
  information towards the applications and sensing
  systems depending on their application category
• Application category 0 LDM-DB specific services
  (LDM margin provision, transaction handling on
  the LDM-DB)
• Application category 1 Certified SAFESPOT
  applications that provide transactions for
  changes in the LDM-DB on the sensing system side
  (SP1, SP2) and SP4, SP5 applications that provide
  information that will be communicated to the
  sensing systems and possibly put on the
  communication network
• Application category 2 SAFESPOT applications
  that have access towards the LDM-DB but dont
  provide further data to the sensing systems or
  the communication network.
• Handles all safety relevant information that
  shall be shared and needs to be available for
  more than one cooperative systems safety
  application
• The Local Dynamic Map is considered as database
  in SAFESPOT. Further specifications will be
  handled according to this assumption!

SINTECH Local Dynamic Map LDM and Broker

• Broker query management via
• Query coordination and optimization
• Application configuration file of possible
  needed data

8
SINTECH Local Dynamic Map Message broker

• The message broker will push all safety relevant
  data on the communication network according to
  all over agreed defined rules (SP7)
• The focus is set on safety relevant data that can
  support other actors (cooperative approach)
• The message broker will not provide all dynamic
  LDM content!
