The NEXT-ITS deployment activity consists of 13 Measures where each contain deployment efforts including one or more of the implementation elements defined for a specific segment of the corridor:
- Data acquisition: Improved detection and status monitoring through installations in the road network (e.g. sensors, cameras) or use of new sources for data acquisition (e.g. mobile units)
- Data and service management: Implementation and upgrade of facilities at e.g. Traffic Centrals for data mining, data fusion and data quality control
- Data dissemination (exchange): Making the information available for service providers (internal and external) through channels like DATEX II
- Service provision to end user: Providing end user services through road side installations (e.g. VMS information panels), through internet services which could include apps for mobile devices
The Measures in NEXT-ITS are presented in detail below.
Measure 1 – Safety related and real-time traffic information
A basic problem of traffic information services is the low level of data quality for real-time traffic information services, as the current travel time service is not performing well in snowy and wintery road conditions due to chosen technology. Therefore a new service utilizing floating vehicle and cellular data will be taken into use in 2014. Also other sources of data are available but it has proved difficult to integrate them into the Finnish Transport Agency databases and services. Concerning safety-related information, the basic problem has been the current data management and operator support systems with little integration resulting in too low performance in timeliness, latency and error probability in order to facilitate the provision of safety-related information services.
The measure aims to eliminate the current problems in traffic information services as well as traffic management services. It focuses on improving the quality of traffic information services by developing a common user interface and an integration layer named T-LOIK.
Measure 2 – Safety Related and Real-time Traffic Information
Data Acquisition and Data Management
Road weather stations mainly measure out weather related parameters (temperatures, humidity, precipitation, wind-speed etc.), but the stations can be equipped to also measure out e.g. traffic conditions. Some of the stations are equipped with cameras. The cameras are used to visually verify the actual weather situation, road and traffic condition. This is extra important for some parts of the network, e.g. along the coast where fog can be hard to detect with other types of sensors. Several camera pictures (webcam´s) are also provided to road users via internet (trafikinfo.trafikverket.se).
This measure includes upgrading of 10 road weather stations, e.g. with cameras, along the Swedish west coast between Gothenburg and the Norwegian border which will be used to verify the measured data in order to enhance the quality of information and content provided for Traffic Condition, Weather information, Temporary slippery road and Exceptional weather conditions. The measure includes enhancement of local climate models, models for road status prognosis (stretch-oriented) and planning of actions.
Measure 3 – Safety Related Traffic Information
This measure contains two activities aiming at improving the quality of information available for traffic centres; road work status reporting and travel time measurement through floating car.
The reporting of road works is to a large extent dependant on manual reporting from entrepreneurs. To enhance the quality of data there will be a general improvement of work process and systems for data collection regarding road works, where the data collection will be made automatically and by using dedicated apps. The apps will be developed by in-house resources and by procured consultants.
In addition, an extension of the use of floating vehicle data is included in order to verify and enhance the quality of data, e.g. corridor coverage, and information in the traffic centre systems regarding travel times. Travel time data will be acquired internally and from external information providers.
This measure will improve the level of service for all safety related services and for “short term road works” it is expected to reach minimum level for the service.
Measure 4 – Real-time Traffic Information
Data Management and Data Dissemination
Swedish Transport Administration has four traffic centres throughout Sweden. These centres operate the various traffic control and traffic information systems available on the national road network. The demand for secure communication and integration between IT systems and more efficient and secure way to exchange data between applications, has not been fully met.
The measure aims at secure and coordinated operational IT environments. This includes upgrading of the hardware, new servers to implement secure communication between IT environments and more efficient / secure way to exchange data between applications and support systems. Furthermore the measure will develop better handling of real-time data plus models for prognosis of corridor status and travel times.
Measure 5 – Safety Related and Real-time Traffic Information
There has been identified some lack of quality control of the deliveries from internal TIC systems, like National Traffic Management System (NTS) and National Traffic Information Server (NTIS), via DATEX to external recipients.
This measure aims at developing the NTS, the NTIS and the DATEX node including development of application interfaces (API’s) which will substantially enhance the quality of service provision with regards to all safety related and real-time information. The work is being directed towards adaptation of working routines and processes that are being developed, including the handling of automatically delivered data.
This measure will improve the dissemination and broaden the use of the information among external service providers.
Measure 6 – Real-time Traffic Information
Data Dissemination, Service Provision
The measure includes installation of five variable message signs. It also handles improvement of the internet Traffic Information Service provided by Swedish Transport Administration with enhancement of accessibility to the traffic information through DATEX II. This includes adaptations to receive more automated data and to ensure that the transfer between the systems works flawless with automated alarm on malfunction.
Further measures e.g. roadside equipment along “Norra Länken (Stockholm Northern Bypass)” are being undertaken outside described action and budget. This should lead to a wider use of the traffic information among external service providers.
Measure 7 – Real-time Traffic Information
Acquisition of Real-time data
The measure addresses acquisition of real-time traffic data to enable a boost in the real-time traffic information services to be provided in the future. Tasks to be conducted:
- Preparation and specification of requirements in relation to data types, quantity, quality, usage, interfaces, exploration of possibilities for cooperation with other Danish road authorities on tender and usage, organization etc. (DATEX-II based).
- Procurement of GPS based real-time traffic data from external data providers.
In the last phase, the real-time information obtained will be tailored to and integrated into a number of traffic information services. (NB. The work on developing and deploying the service provision, e.g. work on user interfaces etc., is included in measure 9 - Real-time and Safety Related Traffic Information).
Measure 8 – Real-time and safety related traffic information
Data management: NEXT generation IT-system in the Traffic Management Centre
Today the national Traffic Information Centre/Traffic Management Centre (TIC/TMC) at the Danish Road Directorate has an old central IT-system from 2006. It handles the traffic information, but it cannot be further developed and it does not provide any support to the operator for incident management tasks. The incident management tasks are done in a separate system. The two systems are not integrated, they have entirely different user interfaces, and they are not able to document the entire work flow.
To ensure an efficient operation of traffic information services as well as traffic incident management, a new IT-system is necessary. The development and implementation of this system is an essential element in the build-up of a continuous traffic information service on the Scandinavian – Mediterranean CEF corridor within the NEXT-ITS project. The new system has been specified to give a much better support of all the tasks performed by the TIC/TMC operators, as tasks will be integrated in one system and with one user interface.
The system will be purchased and operated by the Danish Road Directorate.
Measure 9 – Real-time and Safety Related Traffic Information,
Data management, Service provision - Mobile services
The measure addresses provision of new, better and more accessible services, so that the user will have more possibilities to get the information when and where it is needed. A number of dedicated services have been identified to increase the accessibility of information to end-users.
The objective is provision of real-time traffic information as well as safety related information via primarily mobile services, but also on portals and web-TV.
The measure includes development and deployment of mobile traffic information services (apps) with focus on improving the accessibility for end-users, by improving as well the dissemination as the customization of the information.
Quality of road weather information: Specific action within this measure includes improvements in quality, modelling and decision support in relation to road weather information services. The action will result in a higher quality of the road weather information due to more advanced forecasting of conditions.
Measure 10 –Safety Related and Real-time Traffic Information
Service Provision, New map solution for all map-based services
The present map solution is based on outdated technology and a new map solution for all map-based services is needed. The purpose is to obtain only one map with all services integrated, i.e. one technical solution. From a user perspective this will result in e.g. only one place on the web to find all relevant information (e.g. traffic condition, events, road weather, travel time information, winter information, heavy vehicle information etc.). The aim is to achieve a much more user-friendly and well-running map solution with a better functionality and a professional design. The map solution will be based on open standards and will be usable on mobile phones/tablets.
Measure 11 - Safety Related and Real-time Traffic Information,
Data acquisition - Establishing and upgrading Road Weather Monitoring
The measure addresses collection of real-time data on the road weather conditions.
The measure aims at establishing satisfactory monitoring to enable especially safety related information within the categories a) Temporary slippery road and h) Exceptional weather conditions as defined in the delegated act (specification c). Real-time data is also used in the real-time information services on road weather conditions and the winter service.
- The measure will deploy and upgrade 12 weather monitoring systems on new motorway sections and on uncovered part of the corridor and adjacent network. The upgrade includes new webcams, anemometers or new units of measurement.
- Further, GPS equipment in winter service vehicles will be improved and installed to provide real-time data availability for both control and information purposes. From a service perspective e.g. a real-time presentation of the positions of snow ploughs and salt spreaders will be introduced based on the data.
Measure 12 – Safety related and Real-time Traffic Information
Service Provision: motorway control systems including VMS for safety and real-time traffic information
The provision of traffic condition information and traffic alerts through road side panels on motorways is the focus of this measure. The panels will not only communicate the most important safety-related and real-time traffic information (e.g. congestion warning, speed limits, lane closures, accident information, black ice warnings, road works warnings etc.) to road users, several of them will also be equipped to gather traffic (e.g. radar sensors, traffic flow data, etc.) and weather data.
The German motorways A1 (E47/E22) and A27 (E334) are important parts of the Scandinavian-Mediterranean Corridor and connects Scandinavia and Central/Western Europe. However not all sections show adequate traffic flow and safety. Thus, to improve the performance of this corridor and to ensure adequate safety levels, in particular those gaps have to be filled by improved safety-related traffic information services and real-time traffic information service.
And one of those important gaps is the peri-urban section of A1/E22 in Bremen around the motorway junction with A27, where long-distance traffic and local traffic mixes and poses considerable problems for traffic. Another section with considerable problems is located on motorway E234 between Bremen-Horn/Lehe and the motorway junction Bremen. Problems occur in particular concerning traffic flow on the whole section and concerning safety related issues at the motorway junction Bremen. Thus, a line control system will also be implemented for this section
The system will provide real-time traffic information via VMS on the current traffic situation as well as safety-related traffic information concerning congestion warning, speed limits, lane closures, accident information, black ice warnings, road works warnings.
Measure 13 – Real-time and Safety Related Traffic Information
Traffic Centres Data acquisition, Data management and outreach
The measure address improvements of both real-time traffic information as well as safety related traffic information on the southern parts of the corridor section 3 by enhancement and upgrade of the regional traffic centres. The traffic centres are responsible for collecting the data from the monitoring stations, the data processing in the centre, data exchange with other centres and the road side facilities as well as in particular the dissemination of the traffic information to the end users via internet-based or mobile services. As traffic control, traffic management and in particular traffic information is regionally organised in Northern Germany the traffic centres in Bremen, Schleswig-Holstein and Niedersachsen will be involved in the improvement of the traffic information services.
New software for TPEG have to be used for safety-related traffic information. Thus the centres in Niedersachsen and Bremen have to procure the related soft- and hardware.
The traffic Control Centre in Niedersachsen will be upgraded for improved processing of traffic conditions which is the basis for the real-time traffic information provision.
Implementation of an improved main processor for data exchange in the Traffic Centre Schleswig-Holstein. Several sub-systems will be integrated respectively connected to the central computer. The data acquisition for the traffic centre Schleswig-Holstein will be improved by the implementation of improved software for road weather data and monitoring stations. Furthermore also the data exchange will be improved by the implementation of improved and more reliable data connections to several stretches of the motorway network.
For the service to the end user the respective web-based services in Niedersachsen and Schleswig-Holstein will be improved by e.g. additional functions.
