Airport road access wayfinding refers to a process in which a driver makes a decision to navigate using information support systems in order to arrive to airport successfully. The purpose of this research is to evaluate senior drivers’ behaviour of alternative airport road access designs. In order to evaluate the impact of wayfinding, the combination of simulated driving and completion of a questionnaire were performed. Quantitative data was acquired to give significant results justifying the research outcomes and allow non-biased interpretation of the research results. It represents the process within the development of the methodology and the concept of airport road access design and driving behaviour. Wayfinding complexity varied due to differing levels of road-side furniture. The simulated driving parameters measured were driving mistakes and performances of senior drivers. Three types of driving scenarios were designed consisting of 3.8 miles of airport road access. 40 senior drivers volunteered to undertake these tasks. The questionnaire was used as a supporting study to increase the reliability and validity of the research. Respondents who volunteered for the simulated driving test were encouraged to participate in the questionnaire sessions. The questionnaire was answered after each simulation test was completed. The Mean, Standard Deviation (SD) and Two-Way ANOVA test were used to analyse the results and discussed with reference to the use of the driving simulation. The results confirmed that age group has no significant effect of airport road access complexity design on driving behaviour. Although many studies have been conducted on wayfinding in general, a detailed evaluation on airport road access wayfinding network and driving behaviour in respect of senior drivers were still unexplored domains.

Older adult safe driving is a growing public health issue; however, the skill set of occupational therapists that provide services to these older clients is unclear. The extent to which occupational therapists possess the skills to evaluate an elderly person's ability to operate safely an automobile is unclear. Therefore, the purpose of this quantitative, cross-sectional survey was to determine the current capacity building needs of occupational therapists (OT) related to older driver screening, assessment, and intervention. The ecology of human performance framework was the theoretical base of the study. The independent variables were the OTs' training related to older drivers, the OTs' current driving-related professional activities, and the OTs' continuing education interests. The dependent variable was the reported levels of competence in screening, assessment, and intervention, and the covariates were years of experience, level of education, practice setting, gender, and regional location. The survey was disseminated through technological channels of social media and e-mail. The responses from 61 participants were used for analysis. In a descriptive analysis, OTs felt that addressing driving through screening, assessment, and intervention is somewhat important, that currently OTs seldom address driving, and OTs are not very likely to take continuing education courses related to driving in the next 2 to 3 years. In addition, a linear regression analysis determined a relationship between an OT's actual practice and perceived competence. A positive social change of this study emphasized a better understanding of OT's ability to provide driver rehabilitation services to a growing aging population, which in turn promotes safety on the roads.
