What is the Bicycle Data Clearinghouse Project?
This project seeks to compile, organize, make accessible, and create a data standard for bicycle count data collected in Los Angeles County. The project will collect existing data and create an interface for collecting future data, in 1 centralized location. This centralized location is a data clearinghouse (interactive mapping website) built by UCLA, where anyone can access existing data, and where municipalities can add new data that is collected. This project will also create a training manual that clearly explains how to conduct bicycle volume counts. Other elements of the project include conducting counts and surveys at Union Station, and documenting tools for estimating vehicle mile traveled and greenhouse gas emissions reductions from bicycle volume data.
Who is sponsoring this study?
The Los Angeles County Metropolitan Transportation Authority and the Southern California Association of Governments are sponsoring the study. These organizations received funding for this project from a California Department of Transportation’s Community Planning grant. If you have specific questions about any of these sponsoring groups, please contact Alan Thompson (SCAG) or Lynne Goldsmith (Metro).
Many municipalities are interested in collecting bicycle volume data but are not aware of how to go about doing so. In response, this project will provide a training manual to do so. Secondly, the data that do exist are not in any standardized format. This makes it difficult to compare counts from different locations. Because this project is providing a data standard, planners, modelers and researchers can make fair comparisons between locations and years. In particular, travel demand modelers at SCAG need count data to validate their models. Additionally, since travel occurs independently of jurisdictional boundaries, it is important to bring data together which represent all […]

Eric Lee, the president of management consulting firm Bennett Midland LLC, visited the Lewis Center this week to present his firm’s innovative work regarding the economic impacts of reallocation of street space in New York City for dedicated bikeways, pedestrian improvements, and bus lanes.
Mr. Lee first set the stage by showing pictures of the types of projects considered in the study. Quite dramatic changes, such as parking-protected bikeways and the conversion of parking into pedestrian plazas, have taken place in New York City in recent years. Mr. Lee’s research concerns the question, “Will these changes hurt economic activity?”
Mr. Lee’s presentation was an overview of the study methodology and findings. Sales tax receipts provided a direct and impartial measure of economic activity. Mr. Lee’s firm compared sales tax receipts on 11 study corridors with comparison corridors — chosen by a typology to have similar scale and use — as well as with borough-wide sales tax data. Only retail and service-oriented businesses were included in the analysis, because these businesses depend upon customer access (whether by private vehicle, bus, bike, or walking). Mr. Lee displayed some examples of graphs showing retail sales tax receipts over the course of the study. Tax receipts on a study corridor, a comparison corridor, and borough-wide receipts would be shown on the graph, offering the audience an immediate visual of how the corridor’s economic activity compared. These graphs included a data point for every quarter and extended for several years. Mr. Lee emphasized the ultimate finding of the study: 8 out of 11 study corridors outperformed comparison sites, which indicates that street improvements “do no harm” to economic activity.
A long and lively question-and-answer session followed Mr. Lee’s talk. Attendees included a member […]
This October, Dr. Yodan Rofe visited UCLA to present his work developing a model for pedestrian activity in Israeli cities. Speaking to a full audience, he discussed the state of the practice in pedestrian modeling and the goals and results of his work in Israel. Dr. Rofe cited the work of Jane Jacobs, Kevin Lynch, and Jan Gehl as theoretical predecessors. He defined and explained the “spatial configuration approach” to travel modeling, which draws on the work of Hillier and Hanson, who pioneered this concept in 1989 with their book The Social Logic of Space. This approach entails formalizing the street network in a city as a set of links and nodes, and assigning values to these links and nodes based upon various measures of their centrality and connectedness in the network.
Dr. Rofe’s work, funded by a national authority in Israel, aims to identify the variables explaining pedestrian volumes in Israeli cities, with a particular emphasis on understanding the movements of children and elderly people. Dr. Rofe’s team conducted pedestrian counts on a representative sample of streets, and then performed a regression analysis to explain pedestrian volumes. His team constructed both city-scale models and neighborhood-scale models, and found that the neighborhood-scale models had greater explanatory power. His team modeled total pedestrian volumes, as well as volumes of children and elderly walking, and found more success modeling total numbers of pedestrians.
Dr. Rofe finds that the models are moderately successful: they can predict pedestrian movements relatively well in some types of cities and neighborhoods (R^2 > 80%), and much less well in other cases, such as when focusing only on children or the elderly, or when predicting movements in outer neighborhoods (e.g. not in city centers). In addition, […]
LOS ANGELES, October 1, 2012 — Businesses along the June 2013 CicLAvia route experienced a 10 percent bump in sales on the day of the event, a new study from the UCLA Luskin School of Public Affairs has found.
The increase was greater among those businesses that engaged with CicLAvia participants such as with a vending table or music. “Active participant” businesses saw their sales increase 57 percent according to the study, with sales revenue increases of $1,356 on average compared to $407 on average for all businesses.
With the eighth iteration of L.A.’s day of car-free streets approaching on October 6, the data gives business owners, residents and CicLAvia participants tips on how to make the most of the unique interactions that happen during the event.
Approximately 150,000 people on foot, bikes and skates experienced iconic Wilshire Boulevard as part of the CicLAvia event on June 23, 2013. Researchers at UCLA Luskin’s Complete Streets Initiative and the Luskin Center for Innovation surveyed a representative sample of brick-and-mortar businesses along the route, comparing sales revenue and foot traffic on CicLAvia Sunday and a Sunday earlier that month.
The researchers found revenues increased by an average of $407 per business—$3,122 in sales on CicLAvia Sunday, as compared with $2,715 on a typical Sunday. When extrapolated along the entire route, this translates into a total sales revenue increase of $52,444 across the 128 establishments that were open during CicLAvia on Sundays in June.
“These numbers demonstrate positive gains for local businesses, but they underestimate the event’s overall economic impact,” said J.R. DeShazo, director of the UCLA Luskin Center for Innovation and principal investigator of the study.
