700,000 carless renters pay extra 13 percent for unused garage parking

posted Aug 7, 2017, 2:03 PM by Chris McCahill   [ updated Aug 7, 2017, 2:06 PM ]

A new study finds that garage parking costs the average renter an additional $1,700 per year (17 percent) nationwide. For the average carless renter, the extra cost of unused parking is $621 per year (13 percent). That amounts to $440 million in losses across more than 700,000 households. This doesn’t include units with surface parking, which are less expensive but make up another 45 percent of apartments, so the total cost is likely much higher.

SSTI releases Connecting Sacramento: A trip-making and accessibility study

posted Jul 25, 2017, 12:58 PM by Chris McCahill

For several years, SSTI has worked to advance best practices in the use of two emerging technologies: accessibility metrics and trip-making data from mobile devices. Our recently completed study, Connecting Sacramento, was an essential part of that effort. This study brings together these technologies and tests their application in identifying and prioritizing first- and last-mile-connections to transit, among other uses.

Safety in numbers and safety by design: A ‘virtuous cycle’

posted Jul 7, 2017, 9:36 AM by Chris McCahill

Two recent studies reiterate what makes safer walking environments: more pedestrians, according to one, and well-connected networks of local streets, according to the other. Taken together, these studies build upon growing evidence that the safety benefits of cities designed for walking and biking are self-reinforcing and extend to drivers as well.

Accessibility for all: Open source options for measuring access to destinations

posted Jun 19, 2017, 11:38 AM by Chris McCahill   [ updated Jun 19, 2017, 11:39 AM ]

As highlighted in two recent SSTI webinars in March and April of this year, accessibility measures are becoming more useful in practice. The most notable examples rely on proprietary data and methods, but open source approaches are also gaining traction, while highlighting the need for more reliable, open data.

Accessibility measures describe how easily people can reach destinations, usually in terms of travel time, given the existing transportation system and land use patterns.
