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
公路途经区域的生态环境不同,其对建设响应程度也不相同,公路建设强度的不断增大对生态系统的扰动问题日益突出。因此,在遥感(Remote Sensing,RS)、地理信息系统(Geographic Information System,GIS)技术的支持下,选取金港高速公路沿线...公路途经区域的生态环境不同,其对建设响应程度也不相同,公路建设强度的不断增大对生态系统的扰动问题日益突出。因此,在遥感(Remote Sensing,RS)、地理信息系统(Geographic Information System,GIS)技术的支持下,选取金港高速公路沿线1km范围内典型区域为研究案例,以生态恢复力和生态抵抗力为指标,采用对比分析法,对2017—2021年金港高速公路沿线典型区域生态韧性演变特征进行研究。结果表明,在2017—2021年磅士卑省研究区和戈公省研究区土地利用转移中,转出面积最大的林地面积减少约24%,未利用地转入面积增加一倍,各土地利用类型重心向公路修建方向偏移。土地利用类型总体上呈现自然属性降低、人为属性升高的趋势;2017—2021年两个研究区的生态韧性都呈下降趋势,呈“东大西小”的演变走向。展开更多
