Walkability: To Quantify Or Not To Quantify, William W. Riggs Nov 2015

Walkability: To Quantify Or Not To Quantify, William W. Riggs

William W. Riggs

Academics and policy makers have developed quantitative approaches to judging how conducive a location is to walking. This has resulted in new terms like “walkability,” and the trademarked industry term Walk Score has entered the lexicon because of www.walkscore.com. The website rates one place against another, implying that some areas are a “walker’s paradise” and others are not. Some believe that the Walk Score provides a direct and replicable method to benchmark or measure walkability. While as a metric walkability indices typically use three key factors (proximity to goods and services, population dynamics and the concentration of street intersections, i.e. …


Cargo Bikes As A Growth Area For Bicycle Vs. Auto Trips: Exploring The Potential For Mode Substitution Behavior, William W. Riggs Oct 2015

Cargo Bikes As A Growth Area For Bicycle Vs. Auto Trips: Exploring The Potential For Mode Substitution Behavior, William W. Riggs

William W. Riggs

Cargo bikes are increasing in availability in the United States. While a large body of research has continued to investigate traditional bike transportation, cargo bikes offer the potential to capture trips for those that might otherwise be made by car. To investigate this, data from a survey of cargo bike users are evaluated using descriptive and inferential statistics. The survey queried how use and travel dynamics of characteristics with the hypothesis that cargo bike ownership has the potential to contribute to mode substitution behavior. From a descriptive standpoint, 68.9% of those surveyed changed their travel behavior after purchasing a cargo …

The City of San Luis Obispo (SLO) has eleven official public open spaces. Managing these places presents a challenge in providing top-tier environmental stewardship, while also accommodating passive recreational use and access, in an era of fiscal limitations and competing priorities. Given that reality and the changing population dynamics in the US, providing equal access to these facilities is of increasing importance, whether by car, bike, on foot or via public transit. These open spaces provide value (environmental, economic and social) primarily to residents, as well as visitors, and gaining a data-driven understanding of that value was a primary goal …

The Cost Versus Price For Parking Spaces At Major Employment Centers: Findings From Uc Berkeley, Tudela-Rivadeneyra, Manish Shirgaokar, Elizabeth Deakin Aldo, Manish Shirgoakar, Elizabeth A. Deakin, William W. Riggs Jan 2015

The Cost Versus Price For Parking Spaces At Major Employment Centers: Findings From Uc Berkeley, Tudela-Rivadeneyra, Manish Shirgaokar, Elizabeth Deakin Aldo, Manish Shirgoakar, Elizabeth A. Deakin, William W. Riggs

In dense urban areas, surface parking often poses an opportunity cost, and reuse of the land for urban development with parking relocated to a multistory 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 a substantially higher-cost case, the University of California, Berkeley. The Berkeley case illustrates how replacement of …
