Transit Access Across America

Friday, November 17th, 2017
Metropolitan areas ranked by total employment

This study estimates the accessibility to jobs by transit and walking for each of the United States’ 11 million census blocks, and analyzes these data in 49 of the 50 largest (by population) metropolitan areas. Travel times by transit are calculated using detailed pedestrian networks and full transit schedules for the 7:00 – 9:00 AM period. The calculations include all components of a transit journey, including “last mile” access and egress walking segments and transfers, and account for minute-by-minute variations in service frequency.

Multimodal Transportation Alternatives for Minnesota

Wednesday, December 24th, 2014

This paper looks at alternatives for promoting and strengthening multimodal transportation in rural and small urban areas. It outlines 65 different innovative activities around the United States that have been undertaken to promote multimodalism in rural areas and smaller towns. These activities are grouped into six categories: improving transit options; accommodating alternative vehicles; supporting pedestrian and bicycle travel; multimodal land use planning; the use of financial incentives to promote multimodal land use development; and other alternatives that do not fit in these five categories.

Access Across America: Transit 2014

Friday, October 10th, 2014
Atlanta-Sandy Springs-Marietta, GA

ACCESSIBILITY OBSERVATORY, UNIVERSITY OF MINNESOTA
Accessibility is the ease of reaching valued destinations. Accessibility can be measured for various transportation modes, to different types of destinations, and at different times of day. There are a variety of ways to define accessibility, but the number of destinations reachable within a given travel time is the most comprehensible and transparent—as well as the most directly comparable across cities. This report focuses on accessibility to jobs by transit. Jobs are the most significant non-home destination, but it is also possible to measure accessibility to other types of destinations. Transit is used for an estimated 5% of commuting trips in the United States, making it the second most widely used commute mode after driving.

Mitigating Run-Off-Road Crashes

Wednesday, August 28th, 2013
ROR Crashes

INTELLIGENT TRANSPORTATION SYSTEMS INSTITUTE
UNIVERSITY OF MINNESOTA
While substantial steps have been taken to flatten curves, widen roads/shoulders, impose barriers, and remove collision-prone objects, ROR crashes consistently account for nearly half of all fatal crashes. The introduction of rumble strips to notify drivers of an impending lane departure has spurred other methods of notifying and preventing lane departures via in-vehicle systems (e.g. auditory/visual warnings and haptic/tactile alerts). While these Lane Departure Warning Systems (LDWS) show some promise in successfully warning drivers of impending lane departures, their ability to appropriately capture attention, convey information, and guide an appropriate response must still be refined to consistently prevent ROR crashes.
