2. DATEX II from Data Delivery to Road Network Operation  Requirements  Operators Needs to Manage Devices based on Conditions which may arise in neighboring Network VMS Messaging / SignSetting Cameras, Lane Control Systems, Traffic Lights  activate Combined Network Operation Traffic Management Plans (TMPs / TMPlan)

3. Background  Easyway DATEX II ESG2 TMS-SA03 “DATEX II and TMPs” joined action with DATEX ESG5 task force  Delivered Proposed Extension  FR-ES Pilot  Italian Motorway Operation Exchange  VMS oriented  Evolving TMP Model: IT TMPlan Extension on www.datex2.eu  EIP CIS Workitem Started 2015  TMPlan as specialization of Collaborative ITS Services  Use Case Description delivered Input to Exchange Platform Indipendent Model development  CIS and TMPlan Model delivered In the time needed to deliver an updated Exchange PIM, DATEX II Organisation managed to publish 2016 as version 2.3 extension

4. Information Exchange among Centres Information Delivery What happens ? Traffic Management / Infrastructure Management How to deal ? Improving Safety – Environment - Comfort Objectives

5. DATEX II System Boundaries Business Case: Information Delivery Main goal: Exchange Information among Centres

6. Data Delivery Business case  Data are delivered with only request to be received and syntactically checked  ACK - RECEIVED !

7. D2 CIS Business case  Data are delivered  To activate a processing based on those data Synthactic & Semanthic relevance Processing Results: Feedback ! CIS Domain Data Delivery

8. What is a CIS ? TMPlan perspective  In TMPlan perspective ITS Services are Services offered by a Road Operator or TCC Operator to improve the road network performance, increase safety and reduce pollution

9. ITS Services  Traveller Information  Traffic Management  Freight and Logistic

10. ITS Services Book and Usage of Resources offered by Infrastructure or Road Operator, Authorities, TCC, SP ( ITS Centres)  Broadcast Information  Network Management By means of devices and operator actions Closures, roadworks, alternative paths, lane closures, dynamic lane management, hardshoulder running, traffic lights, VMS setting Patrols to control and manage traffic  Infrastructure usage (Safety) Park Spaces Booking Tunnel Driving Slot / Rerouting Custom Check Services

DATEX Collaborative ITS Services Use of ITS Services among two or more ITS Centres to achieve a common goal  CIS operating implies  Semanthic  Handshaking DATEX Model for Semanthic Request and Feedback Information Exchange Specification for full interoperability  DATEX II used for triggering Distributed ITS Services

14. CIS Requirements and Design  Based on experience about impact on road conditions and frequency of situation occurring, Traffic Engineers may design solutions to cope with problems which frequently arouse in road operation or High Impact Situation.  We can depict a CIS Design generalizing TMPlan design expressed in Easyway TMS DG
