This article presents a concept of a Web-based spatial multiple criteria evaluation tool for individual and group use called Choice Modeler (CM). CM was originally conceived as part of a larger Participatory Geographic Information System for Transportation project (PGIST; aimed at developing and evaluating Internet-hosted capabilities to support participatory decision processes. CM is designed to be either a part of a larger information system such as PGIST or a standalone tool used for evaluation of decision variants. The decision support functions provided by CM aid in reducing the cognitive complexity of the decision space characterized by multiple decision options, evaluation criteria, and criterion weights. This is achieved by incorporating in CM the sensitivity analysis functions for the identification of criteria that do not influence the decision option ranking. Users can remove such criteria from further consideration and thus lessen the cognitive burden of evaluation, which may be essential in multi-stakeholder participatory decision processes. The additional capabilities of CM include a vote aggregation function to collate individual option rankings into a group ranking, and measures of agreement/disagreement to inform the participants about a group-derived desirability of specific decision options. The design of CM was implemented using Web-service architecture. In the article we describe the design of CM and discuss its advantages and limitations.

Swobodzinski, M. and Raubal, M. (2009). An indoor routing algorithm for the blind: Development and comparison to a routing algorithm for the sighted. International Journal of Geographical Information Science, 23(10): 1315–1343

This paper presents a prototypical implementation of a non-network-based indoor routing algorithm for the sighted and the blind. The spatial abilities of the visually impaired are discussed. Former approaches of outdoor navigation systems for the blind are analyzed and deemed inappropriate for the purpose of modeling indoor navigation. The proposed routing algorithm for the blind calculates routes based on physical characteristics of traveling with a long cane. The algorithm distinguishes between clues, landmarks, obstacles, and hazards along the feasible paths and selects the optimal route by trading off distance and the number of landmarks and clues along a route. Subsequently, the routes for the blind are compared to routes calculated by the routing algorithm for the sighted. The paper asserts that the proposed indoor routing algorithm leads to more suitable routes for the blind.

Swobodzinski, M. and Jankowski, P. (2014). Understanding user interaction patterns within online systems for public-participation transportation planning. Transactions in GIS, 18(3): 401–420

Many research projects in public-participation geographic information systems focused on the development of software prototypes that were conceptualized to complement traditional forms of public participation. Given the challenges introduced by the heterogeneity of their user base, system design, and decision making process, empirical evaluations of such systems based on actual use have been scarce. This article reports on a rigorous empirical assessment of human-computer interaction of users of a web-based system for participatory transportation planning. We devised three groups of participants with below average, average, and above-average interaction duration through hierarchical cluster analysis. Subsequently, the characteristics of the clusters were subjected to logistic regression analysis to determine the significance and strength of statistical associations between duration of interaction and a host of individual-level variables. Our results indicate a statistically significant reduction of the odds-ratio for participants with above-average duration of interaction in the case of no prior experience with online transportation discussions. No significant associations were found between overall duration of interaction and sociodemographic background, cognitive decision-making style, and travel behavior. We advocate for the development of adaptable participatory systems which accommodate flexibility in terms of both the user interface and pathways of the decision making process.

Swobodzinski, M. and Jankowski P. (2015). The role of location and cost in individual choices of transportation improvement projects. The Professional Geographer, 67(4): 527–540

Transportation improvement programming is a process in which substantial resources are allocated to transportation infrastructure projects based on public input. This article reports on individual choice making in the context of a Web-based platform for public participation in transportation improvement programming. Based on the locations of the proposed transportation projects, we determined the extent to which the location and the cost of transportation projects informed individual choices regarding selections of road and transit projects. The presented analysis aims at uncovering factors that inform the choices of individuals in the context of transportation improvement programming along the dimensions of self-centered and selfless decision making. Such insight garners understanding of the requirements of and expectation toward Web-based public participation systems and participatory processes. Our results indicate a prevalence of preferences for projects within the vicinity of the individual’s home, work, and travel locations. In addition, the participants opted for project funding mechanisms under which regular residents, who might not benefit directly from a project, would pay more than the participants who selected the projects. These behavioral patterns evidence predominately self-centered choice-making behavior of participants in deliberation-centric, web-based transportation planning.

Swobodzinski, M. and Jankowski, P. (2015). Evaluating user interaction with a web-based group decision support system: A comparison between two clustering methods. Decisions Support Systems, 77: 148–157

Task-Technology Fit theory and the Technology Acceptance Model identify system utilization as an important indicator for the performance of complex software systems. Yet, empirical evaluations of user interaction with group decision support systems are scarce and often methodologically underdeveloped. For this study we employed an exploratory evaluation of user interaction in the context of web-based group decision support systems. Specifically, we used information-rich server logs captured through a web-based platform for participatory transportation planning to identify groups of users with similar use patterns. The groups were derived through multiple sequence alignment and hierarchical cluster analysis based on varying user activity measures. Subsequently, we assessed the reliability of the classifications obtained from the two clustering methods. Our results indicate limited reliability of classifications of activity sequences through multiple sequence alignment analysis and robust groupings from hierarchical cluster analysis for user activity initiations and durations. The presented work contributes a novel methodological framework for the evaluation of complex software systems that extends beyond the common approach of soliciting user satisfaction.
