A service description framework for intelligent transport systems : applied to intelligent goods
- 2012
-
Konferensbidrag (refereegranskat)abstract
- Purpose The primary objective of this paper is to propose a framework for specifying and analyzing Intelligent Transport System (ITS) services. Design/methodology/approach Essential service information are identified and stated in a uniform way. A separation into an abstract description, focused on what the service does, and a concrete description, focused on how to perform the service tasks, is made. Findings The proposed a framework has been used for specifying and distinguishing ITS services and for different types on analyses, e.g. service composition/decomposition analyses and architecture analyses. Original/value The usefulness is illustrated by an architecture choice analysis applied on a specific intelligent goods service. Apart from ITS services, the framework has the potential to also apply to other types of information services.

Analysis Of Telematic Systems For Added Value Services In Road-Based Vehicle Freight Transports
- 2008
-
Konferensbidrag (refereegranskat)abstract
- Added Value Services (AVS) for road based freight transportation have gained the attention of public authorities, industry and the private sector. It is accentuated by systems developed or be-ing under development for road user charging, which have the potential to support additional ser-vices through sharing of functionalities (e.g. communication, positioning and payment). To de-sign telematic systems with many services, the relationships underlying such services and neces-sary functionalities is challenging to analyze. The aim of this paper is to develop a map or guide between important AVS and their functionalities that can be used as a foundation for analyzing potential system architectures for achieving such services. The paper attempts to address differing interest between commercial stakeholders and public authorities in deploying telematic systems for AVS. An analytical method for studying synergy behaviour between road-based telematic services, and required functionalities is proposed. The method is based on a modified hierarchical cluster agglomeration and is inspired by multiuse component based software design. Results of applying the method on AVS in the Swedish Road User Charing system shows that the choice of functionalities play an important role in estimating the synergy for a group of AVS, and hence in the architecture.

Konferensbidrag (refereegranskat)abstract
- Intelligent Truck Parking (ITP) involves efficient management of information as a tool for addressing some of the problems related to truck parking, such as, the inability to navigate to, or reserve a parking space. Different telematic services (ITP core services) may be required to address different stakeholder needs, e.g., a navigation service for finding the way to a truck parking area, and a reservation service for assuring the availability of a parking space when in the parking area. In addition to ITP core services, there are several other telematic services that address transport problems in general. If the synergies of different services are taken into account during design and deployment of telematic services, cost reduction may be achieved through functionality sharing. In this article, we have identified services that are relevant for sharing functionalities with ITP core services, estimate functionality costs and perform a synergy analysis to assess the marginal cost savings as a result. Overall results indicates that Traffic Information Broadcasting (TIB), Estimated Time of Arrival (ETA) for goods, and Geo-fencing (GEO) can form clusters with ITP core services that could lead to better cost savings compared to the rest of the services studied.

Tidskriftsartikel (refereegranskat)abstract
- A method for assessing potential synergies among different sets of transport telematic services (TTSs) is suggested. An Intelligent Transport System enhances transport by delivering one or more TTSs. The ability to deliver multiple TTSs to address a wide range of stakeholder needs is gaining momentum, not only from a marketing perspective but also from a technological perspective. The total cost of TTSs can be reduced if they share functionalities (i.e., sub-services provided by telematic systems). We show how this synergy can be assessed with the help of clustering methods. Knowledge about possible synergies of functionalities is useful in the (re)design and eventual deployment of TTSs, especially when the underlying telematic systems are able to support multiple TTSs. To adapt the clustering method for this purpose, we suggest a mathematical formulation of synergy among functionalities of TTSs. By applying the method to a set of 32 TTSs, we obtain a cluster formation of these TTSs according to their synergy measures. Overall, the results suggest that the joint implementation of TTSs targeted toward some problem domains can lead to significant cost savings, for example, Road User Charging, Infrastructure Repair and Maintenance, and Information on the Transport of extra large goods for the management of road transport infrastructure.

Tidskriftsartikel (refereegranskat)abstract
- This study describes transport telematic services (TTSs) for road-based heavy goods vehicle (HGV) transport and suggests a method for assessing the societal value of different TTSs. For decision making related to the selection of services to promote by potential investors, for example, governmental organisations and service providers, quantified service value can simplify the decision process by enabling comparison between TTSs. Moreover, these values can serve as inputs to quantitative analysis of service architectural system designs. The authors suggest a method for assessing the societal values of TTSs using potential saving indicators (PSIs), estimated in the context of Swedish HGV freight transport. To illustrate the proposed method, 32 services are analysed, and their societal values were quantified and compared for the Swedish HGV market. Results based on estimated values of PSIs and potential percentage savings indicate the following HGV-based TTSs to be of high societal potential: transport resource optimisation, dynamic traffic information, navigation, road hindrance warning, theft alarm and recovery, accident warning information, intelligent speed adaptation, eCall, en-route driver information, transport order handling, road user charging and sensitive goods monitoring.

Modeling Service Quality and Benefits of Multi-Service Architectures in Road Transport Telematic Applications
- 2010
-
Konferensbidrag (refereegranskat)abstract
- Modeling benefits and Quality of Service (QoS) for Multi-Service Architectures (MSAs) is important to enable service providers offer the best Transport Telematic Services (TTSs) with high societal benefits to users. This study models how different QoS characteristics may influence potential benefits of MSAs for road based freight TTSs. This is achieved by modeling the QoS degradation under conditions of shared resources and including costs associated to such degradation to determine the benefits as the difference between the costs and societal value of the applications. A system performance oriented QoS measure has been introduced in coming up with a MSA benefits model, providing a possibility to capture different quality attributes, desired performance levels, and even the possibility to introduce desired priorities between applications and quality attributes.

Tidskriftsartikel (refereegranskat)abstract
- Transport telematic systems, also known as intelligent transportation systems, can be expensive to implement but the services they provide may offer substantial benefits. However, what services the system can provide depends on the architectural choices made, which also affects the cost of the system. We propose an optimization model to support a more informed decision before investing in a multiple service transport telematic system. The model evaluates the possible choices of services and architectures, and aims to maximize the total net societal benefit. We argue that the optimization model can provide support for strategic decisions by highlighting the consequences of adopting different system architectures, including both societal value and cost. This can be useful for decision makers, such as governments, road transport telematic service providers, and commercial road freight transport operators.

Optimization based modeling of multi-service architecture concepts in road transport telematics
- 2009
-
Konferensbidrag (refereegranskat)abstract
- As a result of their high economic costs and unforeseen impacts on society, pre-implementation evaluation of telematic systems is important and can lead to time and cost savings. This article presents an optimization perspective for evaluating conceptual options of transport telematic architecture in relation to benefits to the society. These benefits are evaluated in the context of multiple services and provide one way for comparing between alternative conceptual options for telematic system architectures that can support multiple services. An optimization model is proposed and preliminary results of beneficial services for different architecture options highlighted

Proposed Core Services for the Deployment of Intelligent Truck Parking
- 2012
-
Konferensbidrag (refereegranskat)abstract
- This article suggest Transport Telematic Services (TTSs) to facilitate the realization of Intelligent Truck Parking (ITP) concept i.e. ITP core services e.g. a service that can support real time reservation of truck parking space using for instance mobile phone messaging capabilities. We consider ITP to include the collection, processing and delivery of information about Truck Parking Areas (TPAs) that may take place during the planning and execution of transportation services. A key feature for ITP core services is to achieve efficient information exchange related to TPA so as to improve the overall performance of the transport system. We suggest core services seen to have a potential for achieving ITP. Our suggestions are based on studying “what” kind of information exchanges among TPA stakeholders “when” and “where” the information is exchanged in relation to transport related challenges that are addressed with such information. Hence we suggest Truck Parking facility Utilization (TPU), Goods and Vehicle Safety assurance information (GVS), Parking Location Guidance (PLG) and Parking Reservation (PAR), as ITP core services.

The Value of transport telematic services in heavy goods vehicle transport
- 2009
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The number of Telematic services targeted toward road freight transport, mostly for improving the efficiency of transport related activities have increased in recent years. Interconnected issues such as congestion, fuel consumption, travel time, reliability etc, are treated independently due to the sometimes competitive nature of objectives among service providers. As a result, the services are not developed to facilitate a common level of analysis and comparison. This makes it hard to establish a criterion for generating quantified values that can support analysis for decision makers (potential investors) in selecting the type of services to promote e.g. governmental organizations. This work addresses this issue by proposing an approach for describing services and a set of criteria to generate service societal values under a given set of assumptions. Each service is specified using a range of general to specific dimensions i.e. motivation, usage domain, users, functionalities, and value indicators. Based on the proposed set of criteria, 32 services are discussed, and their societal value quantified and compared for the Swedish heavy good vehicle market. Thus, the work provides an approach toward a common perspective for quantitative analysis of services to influence design and investment decisions. The methodology has been used to estimate the TTS societal values for the Swedish HGV market. The values obtained show a wide variation 14000€ to 25177000€ between various TTSs
