Towards a better understanding of trip satisfaction, behavior and needs among different groups of population over time.

21世纪交通规划者和工程师面临的许多最重要的挑战涉及确保发展和增长的好处在社会各群体之间公平分享。越来越多的人期望运输系统提供的社会效益远远超出流动性：减少温室气体排放，为所有群体提供公平的机会；减少社会排斥；个人利益最大化；确保不同交通方式的通勤者满意，以及社区的宜居性。然而，如何理解、度量和建模这些好处并不总是很清楚，并且是许多从业者面临的挑战。我的项目的长期目标是在上述领域产生有价值的研究，这将对现实世界产生影响。我的第二个长期目标是继续为地方、国家和国际运输机构和公司提供高素质的人才。在这样做的过程中，我的计划包括几项研究，这将有助于我实现我的目标。第一项研究涉及对一段时间内的可达性进行建模，以更好地了解不同社会经济地位的家庭如何“应对”当地和区域可达性的变化。第二个项目确定了居住在蒙特利尔的老年人满足和未满足的交通需求。而第三部分则开发了一些方法，以便在控制态度和习惯的同时，更好地了解活跃的交通用户（公共交通、骑自行车者和步行者）对旅行的满意度。第四项也是最后一项是在大规模调查分析的基础上制定更好的过境市场细分。该研究计划预计将对交通工程和规划领域产生各种影响。首先，我们将继续努力培养高素质的人才，这是我的团队在过去五年中成功做到的，我培训和支持了24名不同的学生。其次，该研究将试图回答几个研究问题，这些问题不仅对交通研究人员很重要，而且对加拿大的从业者（工程师和规划师）至关重要，因为他们正在努力为加拿大人提供更好的交通系统。

Many of the most important challenges facing transport planners and engineers in the 21st century involve ensuring that benefits of development and growth are equitably shared among various groups within society. Transportation systems are increasingly expected to provide societal benefits well beyond mobility: reduction of green-house gas emissions, provision of equitable access to all groups; reduction of social exclusion; maximize benefits to individuals; ensuring satisfaction among commuters of different modes, and neighbourhood liveability. However, how to understand, measure, and model these benefits is not always clear and is a challenge that many practitioners are facing. The long term goal of my program is to generate valuable research in the above mentioned area that will have a real world impact. My second long term goal is to keep providing local, national and international transport agencies and firms with highly qualified personnel. In doing so my program includes several studies that will help me in reaching my goals. The first study involves modeling accessibility over time to better understand how households of different socio-economic status "respond" to changes in local and regional accessibility. The second project identifies met and unmet transport needs of seniors living in Montreal. While the third develops methodologies to better understand levels of satisfaction with trips among active transport users (public transit, cyclists, and walkers) while controlling for attitudes and habits. The fourth and final is developing a better transit market segmentation based on analysis of large scale surveys. The proposed research program is expected to have various impacts in the transport engineering and planning field. First, it will continue our efforts towards training highly qualified personnel, which is something that my group has been successful in doing over the past five years where I have trained and supported 24 different students. Second, the research will try to answer several research questions that are not only important for the transportation researchers, but are of utmost importance to practitioners in Canada (Engineers and Planners) as they are striving to provide better transport systems to Canadians.
