Abstract: From past travel behavior studies it is evident that several trip attributes have been established as key factors in travelers’ decision to use public transport. Using these factors, the present study seeks to provide a psychological perspective of the inconvenience expressed by public transport users’ when making transfers between public-transport modes. The theory of planned behaviorhas been adopted to determine the trip attributes influencing public transport users’ intention to use routes involving transfers. A survey was undertaken in two major transport centers in Auckland, New Zealand. Analysis of results has shown that public transport users’ are intolerant towards greater delays, even if occurrence is rare. Minimization of transfer walking and waiting times increases users’ intention to use transfer routes. Results suggested that reliability of transfers and reduction in journey times has the most influence on users’ intention to make transfers. Findings of the study is expected to support decision makers in developing new transfer routes and improving the quality of existing transfer routes to provide travelers with a possible attractive alternative to automobile.

Abstract: Foveal light detection sensitivity was evaluated in 348 volunteers covering a large age range using an automated perimetry performed in the Humphrey Field Analyzer II. Foveal sensitivity was measured using the Humphrey’s 4–2 bracketing strategy with a 30 dB initial stimulus intensity, at an inferior visual field location, a 0.431 (4mm2, viewed at 30 cm; Goldmann III) spot of white light is presented on a 10 cd/m2 white background. The sensitivity measurement was performed monocularly in both eyes randomly chosen. Our results showed a negative moderate correlation between age and the light sensitivity detection of OD (r= -0.5591; p< 0.001) and OS (r= -0.6021, p< 0.001). A moderate positive correlation was ob-tained between the light sensitivity of the two eyes (r= -0.5986; p< 0.001). We conclude reporting aging effect in the foveal sensitivity light detection suggesting functional decrease in perceptual function guide by developmental changes. Tolerance limits for normative purposes were measured.
