Bikeshare programs are increasingly popular in the United States and
they are an important part of sustainable transportation systems,
offering a viable mode choice for many types of last-mile trips. Most of
the current research on bikeshare focuses on benefits (e.g. reducing
greenhouse gas emissions by replacing auto trips with bike trips) and
system management (e.g., bike repositioning between stations). Far less
attention has been paid to bikeshare programs� potential to provide
greater access to jobs and essential services for underserved
communities. To date, there is virtually no quantitative research on how
to design bikeshare systems for underserved communities.
The purpose of this research is to develop a new quantitative
methodology to fill this research gap. The expected outcomes are to: 1)
quantify the physical barrier (the absence of docking stations), safety
concern barrier, and financial barrier (membership and usage fees) for
underserved communities; 2) provide an index to measure accessibility,
capturing the destination selection of underserved population and
bikeshare potential to diverse services for underserved areas; 3) facilitate
the identification of priority areas for bikeshare investment based on
cycling safety environment, current infrastructure and the potential for
improving access to jobs or essential services. |
