Travel Demand

In dense urban areas, surface parking often poses an opportunity cost, and reuse of the land for urban development with parking relocated to a multi-story structure may be an attractive option. This paper analyzes the cost of replacing surface parking with a parking structure and finds that it may be equally cost effective to pursue travel demand management strategies. The paper analyzes what it costs to build a parking space in a multi-story structure (garage) using US average data as well as data from the case of a typical large US employer, the University of California, Berkeley. The...

The internationalization of policy regimes and the reorganization of the state have provided new opportunities for cities to bypass nation-state structures and work with other cities internationally. This provides greater opportunity for cities to learn from each other and could be an important stimulus to the transfer of policies across the globe. Few studies exist however which focus on the processes that shape the search for policy lessons and how they are affected by the institutional context within which they are conducted. This paper describes research conducted in the field of urban...

The COVID-19 pandemic brought about dramatic shifts in travel, including shopping trips. We investigated changes in eshopping for food and non-food items by supplementing an April to May 2018 household travel survey (n=3,956 households) conducted by the Sacramento Area Council of Governments (SACOG) with a May 2020 follow-on panel survey (n=313 households) during one week early in the pandemic. Results demonstrate that impacts from added pickups and deliveries in the SACOG region during the first two months of the COVID-19 pandemic were limited and did not overwhelm curb management at...

With the advent of ubiquitous mobile sensing and self-tracking groups, travel demand researchers have a unique opportunity to combine these two developments to improve the state of the art of travel diary collection. While the use of mobile phones and the inference of travel diaries from GPS and sensor data allows for lower-cost, longer surveys, we show how the self-tracking movement can be leveraged to interest people in participating over a longer period of time. By compiling personalized feedback and statistics on participants’ travel habits during the survey, we can provide the...
