This paper investigates the geographical scale of residential mobility and its impacts on household vehicle ownership and commute mode choice decisions in Hubli-Dharwad twin cities. We have identified three geographic scales of residential mobility – within wards, between wards, and between cities. The descriptive and statistical analyses reveal that households that moved between cities and those moved between wards added more cars post-relocation. Further, households that moved within wards exhibited a higher likelihood of adding the first motorized two-wheeler and increasing their two-wheeler fleet to two. Notably, families that moved within or between wards are observed to increase their two-wheeler fleet from holding two vehicles at their previous home location. Households that moved between cities switched to public transit from private mode use at the previous residential location. The residential mobility model suggests that household heads holding a postgraduate degree and above are more likely to relocate between the cities and less likely to relocate between wards. Households that moved between wards are more likely to switch to motorized two-wheelers for work travel than the households that moved within cities, as implied by the mode choice model. Between-cities movements encourage vehicle relinquishment, as suggested by the statistical model. The study also shows that an increase in land use mix diversity of residential wards decreases households' tendency to procure additional vehicles and encourages personal vehicles' relinquishment.

本文研究了 Hubli-Dharwad 双城住宅流动的地理尺度及其对家庭车辆拥有量和通勤方式选择决策的影响。我们已经确定了住宅流动性的三个地理尺度——病房内、病房之间和城市之间。描述性和统计分析表明，在城市之间移动的家庭和在病房之间移动的家庭在搬迁后增加了更多的汽车。此外，在病房内搬迁的家庭增加第一辆机动两轮车并将其两轮车车队增加到两辆的可能性更高。值得注意的是，观察到在病房内或病房之间移动的家庭增加了他们的两轮车车队，而不是在他们以前的家中持有两辆车。在城市之间移动的家庭从以前居住地的私人模式使用公共交通转向了公共交通。住宅流动模型表明，持有研究生及以上学历的户主更有可能在城市之间搬迁，而不太可能在病房之间搬迁。正如模式选择模型所暗示的那样，在病房之间移动的家庭比在城市内移动的家庭更有可能改用机动两轮车进行工作旅行。正如统计模型所建议的那样，城市间的移动鼓励车辆放弃。研究还表明，住宅区土地使用组合多样性的增加降低了家庭购买额外车辆的倾向，并鼓励了个人车辆的放弃。住宅流动模型表明，持有研究生及以上学历的户主更有可能在城市之间搬迁，而不太可能在病房之间搬迁。正如模式选择模型所暗示的那样，在病房之间移动的家庭比在城市内移动的家庭更有可能改用机动两轮车进行工作旅行。正如统计模型所建议的那样，城市间的移动鼓励车辆放弃。研究还表明，住宅区土地使用组合多样性的增加降低了家庭购买额外车辆的倾向，并鼓励了个人车辆的放弃。住宅流动模型表明，持有研究生及以上学历的户主更有可能在城市之间搬迁，而不太可能在病房之间搬迁。正如模式选择模型所暗示的那样，在病房之间移动的家庭比在城市内移动的家庭更有可能改用机动两轮车进行工作旅行。正如统计模型所建议的那样，城市间的移动鼓励车辆放弃。研究还表明，住宅区土地使用组合多样性的增加降低了家庭购买额外车辆的倾向，并鼓励了个人车辆的放弃。正如模式选择模型所暗示的那样，在病房之间移动的家庭比在城市内移动的家庭更有可能改用机动两轮车进行工作旅行。正如统计模型所建议的那样，城市间的移动鼓励车辆放弃。研究还表明，住宅区土地使用组合多样性的增加降低了家庭购买额外车辆的倾向，并鼓励了个人车辆的放弃。正如模式选择模型所暗示的那样，在病房之间移动的家庭比在城市内移动的家庭更有可能改用机动两轮车进行工作旅行。正如统计模型所建议的那样，城市间的移动鼓励车辆放弃。研究还表明，住宅区土地使用组合多样性的增加降低了家庭购买额外车辆的倾向，并鼓励了个人车辆的放弃。
