Developing Technology Acceptance Models for Decision Making in Urban Management

Abstract

Technology adoption concept refers to a complicated process covering people, technology and the implementation context. In this paper, we (1) review some of the most reliable technology acceptance models such as Technology Acceptance Model (TAM) and its recent versionsTAM2 and 3; (2) review their constructs, and finally (3) discuss differences of those models. The review shows that TAM still needs further development to be applied to transportation and urban planning disciplines. The models are thoroughly discussed how they can be extended in a way to cover transportation, urban planning and infrastructure management disciplines. TAM is extended by additional variables to produce TAM3 as a comprehensive model in information systems, but there is not any evidence showing that the model can be a reliable predictive model for other disciplines. MOJ Civil Engineering Mini ReveiwOpen Access Developing technology acceptance models for decision making in urban management Constructs of technology acceptance modelsIn this section, definitions of constructs which are used in the above mentioned modelsare presented in Table 1. Table 1 Definition of constructs using in different models ModelReference Construction Definition TAM basic construction 10Perceived Ease of Use The degree to which a person believes that using a particular system would be free of effort. 10Perceived UsefulnessThe degree to which a person believes that using a particular system would enhance his or her job performance.10 TAM2 additional constructs 26Subjective Norm Individual's perception that most people who are important to him think he should or should not perform the behavior in question. 15Image The degree to which use of an innovation is perceived to enhance one's image or status in one's social system. 18Job Relevance An individual's perception regarding the degree to which the target system is applicable to his or her job. 26Output Quality The degree to which those tasks match their job goals, people will take into consideration how well the system performs those task. 26Result Demonstrability The tangibility of the results of using the innovation including their observability and communicability. 18TAM3 additional constructs 25Computer Selfefficacy The ability of user to perform a specific task/job using the computer based if the user's belive. 7 Perceptions of External ControlThe degree to which an individual believes that organizational and technical resources exist to support the use of the system. 27Computer AnxietyThe degree of "an individual's apprehension, or even fear, when she/he is faced with the possibility of using computers". 10Computer Playfulness The degree of cognitive spontaneity in microcomputer interactions. Perceived EnjoymentThe extent to which "the activity of using a specific system is perceived to be enjoyable in its own right, aside from any performance consequences resulting from system use". 10Objective Usability A comparison of systems based on the actual level (rather than perceptions) of effort required...
