Research Highlights
Life-Space Mobility and Aging in Place
Ivis Garcia
Alan DeLaTorre
Research on older adults frequently explores the notion of “aging in place”—providing older adults the opportunity to continue to live in their own homes and communities. However one’s ability to stay or leave, particularly in old age, often depends on the built environment. An accessible neighborhood that prioritizes mobility affords the ability to meet basic needs like goods, services, and social activities.
This life-space mobility is rarely applied in the field of urban planning and ar...

Counts provide the foundation for measuring nonmotorized travel along a link or a network and are also useful for monitoring trends, planning new infrastructure, and for conducting safety, health, and economic analyses. Most agencies still use manual counting methods, however over the last decade, several automated technologies have been developed to count bicyclists and pedestrians. Due to cost and other resource considerations, permanent counts are still limited to small subsets of networks...
