Modelling the Dynamics of Urban Passenger Travel Activity of Seniors in an Ageing Population

老龄人口中的老年人(SA)是人口中的一个重要组成部分，而且还在不断增长。由于(相对)现金充裕和时间匮乏，他们对交通系统以及其他支持网络所要求的可达性和机动性水平有很高的期望。我们目前缺乏政策丰富的旅行需求模型，无法帮助理解影响SAPS旅行活动的复杂动态。利用既定的选择方法、互动机构选择实验、面板计量经济学和行为离散选择模型的思想，我们提出了一个旨在理解这些需求的研究计划。特别注重支持网络以及这些网络对汽车和公共交通使用需求的影响，以及满足获得保健支持和休闲设施以及家庭和朋友支持网络的需要。

Seniors in an ageing population (SAPS) are a significant and growing segment of the population. As (relatively) cash rich and time poor, they have very high expectations in respect of levels of accessibility and mobility required from the transport system, as well as from other supporting networks. We currently lack policy-rich travel demand models to assist in understanding the complex dynamics that influence the travel activities of SAPS. Using ideas from stated choice methods, interactive agency choice experiments, panel econometrics and behavioural discrete choice models we propose a research program designed to understand these demands. Special focus is given to support networks and the ways in which these impact on the demand for car and public transport use, as well as meeting the access needs to health-support and leisure facilities and to supporting networks of family and friends.
