Abstract

While a large amount of effort has been devoted to making and updating local transportation plans, little is known about the informational contents of these plans and their use patterns.  This project attempted to identify key informational contents of Californian cities’ transportation plans and to investigate how various stakeholders can use the plan contents through (i) a plan content analysis of a sample of general plans (recently adopted by eight municipalities in Orange County, California) and (ii) a plan use survey and follow-up analysis of survey responses. All plans that were analyzed were found to convey a variety of information about their visions, goals, policies, and implementation strategies, but the plan content analysis revealed substantial variation in the way cities composed their general plans and integrated them with other plans/players. Compared to land use elements, circulation elements tended to focus more on their connections with other agencies (external consistency) than on internal consistency. The plan use survey yielded a low response rate which may indicate limited use of plans in the field. However, a majority of the survey responses were positive about the usefulness and usability of general plans. In particular, the survey participants reported that they found the plans comprehensive, visionary, and well-organized, while relatively lower scores were obtained for two evaluation criteria: ‘[the plan] clearly explains what actions will be taken and when’ and ‘[the plan] is relevant to my everyday life and/or work’. Furthermore, some respondents reported that they used general plans not for their professional duties but for other (non-conventional) purposes, suggesting that plan contents could be used for a variety of decision-making processes.

Implementing SB 743: An Analysis of Vehicle Miles Traveled Banking and Exchange Frameworks

Abstract

Pursuant to Senate Bill 743 (Steinberg, 2013), which reformed the process for California Environmental Quality Act (CEQA) review of transportation impacts to align with greenhouse gas emissions reduction goals, the Governor’s Office of Planning and Research identified vehicle miles traveled (VMT) as the key metric to measure transportation impacts of new developments under CEQA. As a result, project developers will now have to reduce vehicle miles traveled to mitigate significant transportation impacts. In response, state and local policymakers are considering the creation of mitigation “banks” or “exchanges.” This report assesses the structural and legal considerations that could determine which model (i.e., banks or exchanges) and scope are appropriate for each implementing jurisdiction (i.e., city, county, regional, state). This report also analyzes a number of existing programs that provide additional models for implementation.

Public-Private Partnerships Show Promise for Shifting Export of California Produce from Truck to Rail

Abstract

California is one of the largest producers of perishable produce in the world; producing about 25 million tons of fruits and vegetables each year. This sector supports a large transportation industry that handles the exports of these goods. Starting from the 1950’s, the export of produce has gradually shifted modes from rail to trucks. Currently, only 3% of California’s produce is being exported by rail. However, this share has begun to increase due to efforts in private industry to monetize this space, with total rail tonnage exceeding one million for the first time in decades starting in 2012. See Figure 1. Much of this increase is due to the modest success of companies in the San Joaquin Valley aggregating crop exports onto rail unit trains. While utilizing trucking may be cheaper for growers, shippers, and buyers, it has generated a number of negative externalities, including impacts to the environment, public health and public roads (e.g., pavement damage). Encouraging a shift from transporting produce by trucks to rail could help reduce these negative externalities.

Encouraging Mode Shift from Truck to Rail for California Produce

Abstract

California is one of the largest producers of perishable produce in the world. This sector supports a large transportation industry that handles the exports of these goods. Starting from the 1950s, the export of produce has gradually shifted modes from rail to truck. This project builds on the initial work from the “Rail and the California Economy” project by examining the potential of shifting the movement of perishable produce in California from truck to rail. The final report provides a review of the state of the California rail system in terms of perishable produce transport and where there have been recent increases in rail modal share; analyzes and discusses the societal costs of trucking; outlines how PPPs (public-private-partnerships) relate to rail and provides examples of rail PPP in California such as the highly successful Colton Crossing project; and proposes a location in Monterey County where government support through a PPP could result in lasting beneficial changes. In summary, although rail is currently a very small player in the transport of California perishable produce exports, increasing its modal share would be beneficial to the citizens of the state by reducing the number of negative externalities. Public entities should consider different ways, such as PPP, to encourage this growth. In areas where the private sector has already invested significant money, some modal shifts for certain crops have already occurred.

The Impacts of Infill Rail Transit Stations: Implications for the Shinn Station Proposal

Abstract

Infill rail transit stations are being implemented to improve access to transit as well as to encourage and support urban development and revitalization efforts.  The stations are relatively low-cost because they use existing tracks and equipment, but costs vary substantially depending on the complexity of the station design and its surroundings. Travel time savings can accrue to passengers using the infill station, but the added stop will increase time for some riders and may necessitate changes in equipment, schedule, or both.  Ridership at the infill station depends on the size of the area made more accessible as well as the amount of new development and intensified activity that occurs in its vicinity.  Findings from the literature and US examples are used together with a preliminary site assessment and interviews to identify the issues that would be raised by a proposed infill station linking multiple services in the San Francisco East Bay.   The concluding section summarizes factors that should be considered in evaluating the impacts of proposed infill stations and discusses the broader implications for regional planning.

Abstract

This report provides a summary of analyses using data from long-distance tours by each household from an 8-week California Household Travel Survey travel log. The first analysis uses Structural Equations Models (SEM) and a simpler variant called Path Analysis on three censored variables (tour miles by air, miles driving, and miles by public transportation) and two categorical variables (main trip tour purpose) and number of overnight stays. The second analysis uses Latent Class Cluster Analysis (LCCA) to identify five distinct, informative patterns of long-distance travel. This analysis shows that long-distance tours for vacation, business travel, medical, and shopping are substantially distinct in terms of their travel characteristics and correspond to different combinations of other activities in the tour and they are done by different types of households. The methods used here to identify the typology of long-distance travel can be easily expanded to include a variety of other explanatory variables of this type of behavior in more focused data collection settings.

An Analysis of Travel Characteristics of Carless Households in California

Abstract

In spite of their substantial number in the U.S., the research team’s understanding of the travel behavior of households who do not own motor vehicles (labeled “carless” herein) is sketchy. The goal of this paper is to start filling this gap for California. We perform parametric and non-parametric tests to analyze trip data from the 2012 California Household Travel Survey (CHTS) after classifying carless households as voluntarily carless, involuntarily carless, or unclassifiable based on a California Household Travel Survey question that inquires why a carless household does not own any motor vehicle. We find substantial differences between the different categories of carless households. Compared to their voluntarily carless peers, involuntarily carless households travel less frequently, their trips are longer and they take more time, partly because their environment is not as well adapted to their needs. They also walk/bike less, depend more on transit, and when they travel by motor vehicle, occupancy is typically higher. Their median travel time is longer, but remarkably, it is similar for voluntarily carless and motorized households. Overall, involuntarily carless households are less mobile, which may contribute to a more isolated lifestyle with a lower degree of well-being. Compared to motorized households, carless households rely a lot less on motor vehicles and much more on transit, walking, and biking. They also take less than half as many trips and their median trip distance is less than half as short. This study is a first step toward better understanding the transportation patterns of carless households.

Do Compact, Accessible, and Walkable Communities Promote Gender Equality?

Abstract

Directing growth towards denser communities with mixed-use, accessible, and walkable neighborhood design has become an important strategy for promoting sustainability, but few studies have examined whether compact development strategies could help reduce within-household gender disparities in spatial behavior by increasing accessibility. The research team analyzed the spatial behavior of heterosexual married couples in Southern California based on the 2012 California Household Travel Survey and found that households living in areas with greater regional accessibility and neighborhood walkability have smaller, more centered, and more compact activity spaces overall compared to households in less compact areas, and that married pairs living in more accessible areas have greater equality in the size and centeredness of their activity spaces. Results support the hypothesis that compact development provides married couples greater flexibility in how they divide household out-of-home activities by making destinations more convenient. Future research and planning efforts should carefully consider which aspects of compact, accessible development are most effective for a given local context.

State-Level Strategies for Reducing Vehicle Miles of Travel

Publication Date

Abstract

California adopted a statewide target of reducing greenhouse gas emissions to 40% below 1990 levels by 2030. To meet these goals, the state must achieve a 15 percent reduction in total travel by light-duty vehicles by 2050 compared to expected levels. Under current state policies, reductions of this magnitude are likely. This report explores the evidence for strategies to reduce vehicle miles of travel in pricing, infill development, transportation investments, and travel demand management programs. For each category, the report outlines programs from other states that, if adopted, have the potential to reduce (vehicle miles traveled) VMT and thus greenhouse gas emissions.
