Abstract:The automated development of spatial analysis workflows is one of the envisioned benefits of Web services that provide geoprocessing functionality. Automated workflow development requires the means to translate a user objective into a series of geographic information system (GIS) operations and to evaluate the match between data and operations. Even though full automation is yet out of reach, users benefit from formalized knowledge about operations that is available during workflow development. This article presents user support during workflow development based on a recent approach to extended operation descriptions. User support thereby focuses on the discovery of operations across GIS tools and the validation of chains of spatial analysis operations. The required knowledge about operations is stored in a knowledge base, which builds on an approach called geooperators and extends the geooperator approach with a data-type ontology for describing the interfaces of geooperators and for expressing constraints of geooperator inputs. The advantages of the knowledge base are demonstrated for the construction of a multi-criteria decision making workflow. This workflow contains a set of pre-processing tasks for the input datasets and eventually the calculation of a cost distance raster. A critical discussion of the complexity of the knowledge base and a comparison with existing approaches complement this contribution.

“…The use case we look at is a multi-criteria decision making process in the context of transport route planning for a highway in Poland, which was developed by Keshkamat et al [42]. An implementation of this workflow in ArcGIS has been provided by Brauner [15], which is used as reference for the workflow here.…”

“…An economic distance is the distance a commodity may travel before transport costs exceed the value of freight. A traffic assignment model involving a travel distance minimization problem include Beyer's line weight means (LWM) [11]. Dijkstra's shortest path algorithm is easily utilized in LWM as a means of determining a route with the least impedance.…”

Abstract:To elucidate a realistic traffic assignment scenario, a multi-criterion decision system is essential. A traffic assignment model designed to simulate real-life situation may therefore utilize absolute and/or relative impedance. Ideally, the decision-making process should identify a set of traffic impedances (factors working against the smooth flow of traffic) along with pertinent parameters in order for the decision system to select the most optimal or the least-impeded route. In this study, we developed geospatial algorithms that consider multiple impedances. The impedances utilized in this study included, traffic patterns, capacity and congestion. The attributes of the decision-making process also prioritize multi-traffic scenarios by adopting first-in-first-out prioritization method. We also further subdivided classical impedance into either relative impedance or absolute impedance. The main advantage of this innovative multi-attribute, impedance-based trip assignment model is that it can be implemented in a manner of algebraic approach to utilize shortest path algorithm embedded in a Geographic Information Systems (GIS)-Graphical User Interface tool. Thus, the GIS package can therefore handle the multi-attribute impedance effectively. Furthermore, the method utilized in this paper displays flexibility and better adaptation to a multi-modal transportation system. Transportation, logistics, and random events, such as terrorism, can be easily analyzed with pertinent impedance.

“…The need to promote a readjustment in the modal split, in order to develop more sustainable mobility patterns, requires greater investment on the part of the transport operators when it comes to the planning component based on knowledge of the territory. Here, the GIS technologies appear as essential elements to pursue these goals (Keshkamat et al [14]) and this platform aims to promote this new way of looking at operations, either by those planning the transport system and its different networks, or by the transport operator. Nevertheless, for the latter, it is a very penalizing task as it not only obliges him to do surveys, downloads and information updates on the responsibility of other public entities, but he is also deprived of the necessary reading concerning the territories' dynamics for its planning activities and network management.…”

Among other explanatory factors for the worsening imbalance in modal split that has occurred in the last three decades in the AMPorto (considered here with nine counties, according to Law No. 44/91) is a weak competitive capacity of networks of collective use particularly road passenger transport. More than a dozen companies operate in an area of 817 km 2 , providing a disjointed service and therefore extremely punitive to the population.The Portuguese government is carrying out efforts to gather information from carriers. Still, given the possibilities easily reached by new GIS technologies, we admit that there is a data deficit of integration on a territorial basis, also spread over several institutions, which makes the necessary adjustments difficult, whether the decisions by central government and businesses, or those made by the population.The reflection proposed addresses issues concerning the governance in transport -the desire for integration and practice of fragmentation of networks. It stimulates, from the possibilities offered by GIS, the results of a punitive governmental modus operandi to the operations of public transport.The exercise is based on the cross-interpretation between the results obtained with the Normative Ordinance no 32/2009 and what we believe to have been a missed opportunity of a governance exercise in the transport domain.
