However, it remains unclear whether RHAs would be regarded as threats or opportunities among paratransit operators in Asian developing cities. While RHAs have been viewed as disruptive transportation, several studies explored the threats of RHAs on taxi industry—but only a few examined such threats on other paratransit services (e.g., auto-rickshaws). This study assessed the changes in the operational services among paratransit operators who have adopted RHAs. The changes were examined by statistical comparisons using data collected from questionnaire survey with 182 Bajaj drivers in Phnom Penh, January 23-27, 2018, as a case study. Results showed that majority of the interviewed drivers started new services with RHAs less than a year ago—they were younger (88%) satisfied with RHAs and acknowledged improvements on their operational services. The results suggested that RHAs would be opportunities for those paratransit drivers who have adopted them, while they would be threats for those who have not. The collected data serve as useful inputs for future public transport planning in Asian developing cities.展开更多

In addition, it has been mentioned that higher affluent people appear to have higher contention to aircraft noise, but there is little literature explicitly supporting that. This paper investigates the relationships among aircraft noise exposure level, noise sensitivity, affluence status, aircraft noise annoyance, and annoyance by other noise sources (e.g., road traffic and neighbor noise). A structural equation model is developed and estimated using data collected from residents, aged between 18 and 77 years old, living near Manila airport in the Philippines (N = 321). Results show that noise sensitivity, noise exposure level, and affluent status have positive effects on aircraft noise annoyance, suggesting that higher affluent people are substantially more annoyed by the aircraft noise than lower affluent people. The results also indicate that the annoyance by other noise sources is significantly influenced by noise sensitivity (p < 0.01), but not by the affluent status. This implies that people with higher affluent status consider more about the noise generated from aircraft than the noise from other sources. Following an airport development plan, the aviation authorities should also consider the affluent status of nearby communities in order to formulate a better aircraft noise management near that airport.展开更多
