General Introduction
The success of any TCC and TIC relies on the quality and reliability of its
• data, • products and • services
which are based on the
• skills of its personnell,• the quality of its processes and • quality of raw data
What is a QMS?
A Quality Management System (QMS) defines procedures based on the knowledge of the organisation and best practise in order to deliver
improved product (traffic data, traffic information, traffic management) quality
at reduced costs
Hence the QMS tackles organisational and technical issues alike.
Example for organisational aspect of QMS
Status Quo in Switzerland
Political requirements:
• Commitment to sustainable mobility
• Optimal and best intermodal use of the entire transport (road + rail) infrastructure
• Satisfy the requirements of HGV, extra-heavy and dangerous goods traffic
Situation• Transit traffic from northern to southern Europe via Switzerland steadily
increasing• Major traffic problems and congestion on the North-South (N-S) transit
corridor plus high maintenance costs• Severe accidents and fire in long road tunnels
The intermodal truckinfo.ch system
Truckinfo: the inter-modal traffic info. system for heavy goods traffic crossing the Alps
Up-to-date traffic information (available on maps and lists)
information about “Red Phase” information about traffic conditions
at passes and tunnels current booking situation on the
transiting railways (vehicular) best inter-modal routing info info available in 4 languages
The truckinfo.ch system(II)Inter-modal crossborder HGV Inter-modal crossborder HGV routing informationrouting information example: Karlsruhe-CH-Milano Alternatives:green vehicular rail
- with various and best trains- is train already overbooked?
shortest route via Switzerland or (observing the night driving ban!)
detour to avoid Switzerland?
Some Organ. Topics in SwitzerlandMonitoring:
Traffic data collected under responsibility of various organisations such as 25 Kantons (regions), several cities and other institutions (multimodal) resulting in different data formats and quality levels
Cross-border traffic information on N-S alpine corridors is not well harmonised, often occurring on a decentralised basis by regional bodies and by cantons not applying the EU/CEN/ISO standards.
Traffic information:
Traffic information via radio is not synchronised with VMS displays
Harmonisation and centralisation within Traffic Information Management Concept (TIM-CH) by 2012 in two phases
TIM Goals regarding Monitoring
• One centralised traffic information centre at national level
• Harmonised traffic information network at national level
• Concept/rules for collecting traffic data at national level
• Concept/rules for harmonised traffic data management
TIM Goals in related Areas• Standards and directives for quality assurance of TIM
• Concept/rules for synchronised traffic data dissemination at national/cross border level (radio, TV, www, VMS, etc)
• Standardised contracts for traffic info services incl. PPP• Harmonised and completed legal and financing bases• Cross-border harmonised traffic management plans TMP• Harmonised directives and operating manuals for TIM incl. “to do list”
and inventory of responsibilities in TIM• Harmonised basis for education and training in TIM
Benefits of TIM
• More efficient standard. data collection and dissemination
• Lower costs due to only 1 TIM and use of EU standards
• More up-to-date harmonised intermodal traffic data
• Clear responsibilities and competencies on all levels
• One centralised TIM at national level instead of 25
• Standardised TIM at national level harmonised with EU
• Synchronisation (radio/VMS) of traffic data dissemination
Traffic Information Management (TIM) for Switzerland is expected to feature the following benefits:
Optimal traffic flow, less congestion and fewer accidents by optimal use of traffic information and all available transport networks

Examples for Technical Actions
(Please see presentation of Samuel Danaes in this session)
Automatic quality surveillance of detector data in areas with high detector density e.g. within LCS
Detector data of stand-alone loop are uncorrect when received by in the TCC
estimate traffic on site and immediately compare the values in the different chain links online

Conclusion• Every organisation involved in data collection and information
provision has a quality management concept – even if it is not written down
• Different focussing points in different regions will provide high added value concerning the solving of quality problems
• International data exchange will increase in importance
CROSS FERTILISATION AND CO-OPERATION AMONG THE EUROREGIONAL PROJECTS IS HIGHLY PROMISING AND NECESSARY
