    The Moving Ahead for Progress in the 21st Century Act (MAP-21)—the legislation that currently provides funding for federal transportation—allows metropolitan planning organizations (MPOs) or eligible large, urbanized area (UZA) agencies to assume administrative responsibility for Federal Transit Administration (FTA) Section 5310—the Enhanced Mobility of Seniors and Individuals with Disabilities grant program. Caltrans engaged Mineta Transportation Institute (MTI) to conduct research and facilitate a dialogue with the State’s 5310 stakeholders. The MTI team conducted interviews with key stakeholders and Caltrans staff and performed in-depth quantitative analysis of the existing administrative activities of the 5310 program. This research was followed by two statewide 5310 program workshops led by Drs. Ferrell and Appleyard to facilitate discussion among stakeholders and reach consensus on how the new MAP-21 program would be implemented. The key findings from this research and dialogue are: A “full transition” to MPO Program administration could significantly reduce the benefits of the 5310 program for the entire state. A full transition could leave smaller MPOs lacking sufficient administrative funds to adequately run the program in their jurisdictions. Stakeholders are concerned that their local project funding priorities may not receive enough attention if Caltrans retains sole administrative responsibilities for the program. A majority of stakeholders prefer to pursue a partnership with Caltrans to jointly run the 5310 program (the “Hybrid/Partnership Option”). The Hybrid/Partnership Option can provide the maximum amount of flexibility for the program over the long term while building the administrative capacities of all partners

    Understanding the relative attractiveness of alternatives to driving is vitally important toward lowering driving rates and, by extension, vehicle miles traveled (VMT), traffic congestion, greenhouse gas (GHG) emissions, etc. The relative effectiveness of automobile alternatives (i.e., buses, bicycling, and walking) depends on how well streets are designed to work for these respective modes in terms of safety, comfort and cost, which can sometimes pit their relative effectiveness against each other. In this report, the level of traffic stress (LTS) criteria previously developed by two of the authors was used to determine how the streets functioned for these auto alternative modes. The quality and extent of the transit service area was measured using a total travel time metric over the LTS network. The model developed in this study was applied to two transit routes in Oakland, California, and Denver, Colorado

    Neighborhood Crime and Transit Station Access Mode choice - Phase III of Neighborhood Crime and Travel Behavior

    Get PDF
    This report provides the findings from the third phase of a three-part study about the influences of neighborhood crimes on travel mode choice. While previous phases found evidence that high levels of neighborhood crime discourage people from choosing to walk, bicycle and ride transit, consistent with the authors’ hypothesis, they also produced counterintuitive findings suggesting that in some cases, high crime neighborhoods encourage transit ridership at the expense of driving—the opposite of what common sense would suggest. Phase 3 tested possible explanations for these counterintuitive findings with a series of methodological improvements. These improvements were: Improvement 1: Used the Bay Area Rapid Transit (BART) system‘s 2008 Station Profile Survey travel data set to replace the Bay Area Travel Survey (BATS) 2000 data used in previous phases. Improvement 2: Separated drop-off and drive-alone modes in logit models. Improvement 3: Variables at the corridor level replaced previous variables at the transportation analysis zone (TAZ) level. Improvement 4: Average parcel size (APS) variable replaced the intersection density measure of urban design. Improvement 5: Used nested logit modeling techniques. These yielded strong evidence supporting the hypothesis that high-crime neighborhoods encourage driving, and they generated none of the counterintuitive findings from previous phases

    Incorporating Public Health into Transportation Decision Making

    Get PDF
    Investments in transportation have the potential to significantly affect public health outcomes. Decisions to build highways, transit, or bikeways, for example, influence how residents and visitors move around a metropolitan area. Personal travel habits and proximity to transportation infrastructure play a role in how likely people are to be physically active or be exposed to dangerous traffic and toxic pollution. For this study, the research team reviewed the literature that links transportation infrastructure, the surrounding built environment context, and public health outcomes such as chronic heart and lung diseases, obesity, and death. The team then researched publicly available data that planners could use to inform decision-makers about the public health effects of funding certain investments. Finally, the team reviewed the guidelines of existing discretionary grant programs administered by the California Transportation Commission (CTC), and proposed improvements that would better incorporate available data on public health for consideration. These steps can positively influence funding decision-making for better public health outcomes in California

    Toward a Guide for Smart Mobility Corridors: Frameworks and Tools for Measuring, Understanding, and Realizing Transportation Land Use Coordination

    Get PDF
    The coordination of transportation and land use (also known as “smart growth”) has been a long-standing goal for planning and engineering professionals, but to this day it remains an elusive concept to realize. Leaving us with this central question -- how can we best achieve transportation and land use coordination at the corridor level? In response, this report provides a review of literature and practice related to sustainability, livability, and equity (SLE) with a focus on corridor-level planning. Using Caltrans’ Corridor Planning Process Guide and Smart Mobility Framework as guideposts, this report also reviews various principles, performance measures, and place typology frameworks, along with current mapping and planning support tools (PSTs). The aim being to serve as a guidebook that agency staff can use for reference, synergizing planning insights from various data sources that had not previously been brought together in a practical frame. With this knowledge and understanding, a key section provides a discussion of tools and metrics and how they can be used in corridor planning. For illustration purposes, this report uses the Smart Mobility Calculator (https://smartmobilitycalculator. netlify.app/), a novel online tool designed to make key data easily available for all stakeholders to make better decisions. For more information on this tool, see https://transweb.sjsu.edu/research/1899-Smart-Growth-Equity-Framework-Tool. The Smart Mobility Calculator is unique in that it incorporates statewide datasets on urban quality and livability which are then communicated through a straightforward visualization planners can readily use. Core sections of this report cover the framework and concepts upon which the Smart Mobility Calculator is built and provides examples of its functionality and implementation capabilities. The Calculator is designed to complement policies to help a variety of agencies (MPOs, DOTs, and local land use authorities) achieve coordination and balance between transportation and land use at the corridor level

    A Smart Growth & Equity Framework and Tool for Measuring, Understanding, and Realizing Transportation Land Use Coordination for Sustainability, Livability, and Equity

    The coordination and integration of transportation and land use (also known as “smart growth”) has been a long-standing goal for planning and engineering professionals, but to this day remains an elusive concept to realize. As this approach is a widely recognized as key to achieving sustainable, livable, and equitable (SLE) outcomes for individuals and society, a key aim of this report is to instill the coordination of transportation and land use into practice by the collection of key actors and agents (MPOs, DOTs, and local land use authorities, etc.) through new measurement and policy guidance frameworks and tools. A fundamental assumption of this report is that frameworks are needed first to help guide the use of tools to measure and understand urban quality, and then inform policy decisions toward realizing SLE outcomes. Along these lines, this report provides a review of current literature and practice related to measuring and understanding the integration of transportation and land use through the lenses of sustainability, livability, and equity (SLE), specifically focusing on efforts to operationalize the Livability Principles of the 2009 HUD/DOT/EPA Partnership for Sustainable Communities and Caltrans’ Smart Mobility Framework. Specifically, this report builds on the use of various principles, performance measures, and place typology frameworks, along with current mapping and Planning Support Tools (PSTs) in order to develop a framework to: a. Measure SLE urban quality performance urban places b. Understand what this SLE performance means in terms of how to respond with policies c. Provide guidance on how to enact policies to realize more robust transportation land use integration (smart growth) to achieve SLE outcome for society. With this knowledge and understanding we then go into a discussion of tools and metrics and how they can be used. For illustration purposes, this report uses the Smart Growth & Social Equity Calculator (https://smartgrowthcalculator.netlify.com/) – an online tool designed to make key data easily available to all stakeholders so they can more readily make coordinated decisions to that will lead to a more robust integration between transportation and land use. Specifically, the SGE Calculator can help with: climate action planning, VMT analysis related to new CEQA regulations under SB 743 that move us away from LOS, and how to coordinate transportation & land use across the spectrum, from community NIMBY discourses to regional and state transportation planning

    Housing and Mobility Toolkit for San Mateo County

    Get PDF
    Since the end of the Great Recession, San Mateo County has attracted new workers at a record rate without building anywhere near enough housing. This jobs-housing imbalance drives the cost of housing up and forces many moderate and lower-income employees and their families out of the County. A lack of access to quality affordable housing in the County and the entire Bay Area along with limited transportation options means that an increased number of employees drive in and out of the County every workday. The resultant congestion, gridlock, and long commutes along with other negative environmental, social, and economic impacts create a major concern for communities in the County and beyond. Clearly, this problem has two distinct but interrelated dimensions: housing development and transportation planning. A select group of Mineta Transportation Institute (MTI) Research Associates worked closely with representatives from the San Mateo County Home for All initiative to help address this challenge by developing a toolkit of successful case studies with a holistic approach to housing development and transportation planning

    Identifying High-Risk Intersections for Walking and Bicycling Using Multiple Data Sources in the City of San Diego

    Over the last decade, demand for active transportation modes such as walking and bicycling has increased. While it is desirable to provide high levels of safety for these eco-friendly modes of travel, unfortunately, the overall percentage of pedestrian and bicycle fatalities increased from 13% to 18% of total road-related fatalities in the last decade. In San Diego County, although the total number of pedestrian and bicyclist fatalities decreased over the same period of time, a similar trend with a more drastic change is observed; the overall percentage of pedestrian and bicycle fatalities increased from 19.5% to 31.8%. This study aims to estimate pedestrian and bicyclist exposure and identify signalized intersections with highest risk for walking and bicycling within the city of San Diego, California, USA. Multiple data sources such as automated pedestrian and bicycle counters, video cameras, and crash data were utilized. Data mining techniques, a new sampling strategy, and automated video processing methods were adopted to demonstrate a holistic approach that can be applied to identify facilities with highest need of improvement. Cluster analysis coupled with stratification was employed to select a representative sample of intersections for data collection. Automated pedestrian and bicycle counting models utilized in this study reached a high accuracy, provided certain conditions exist in video data. Results from exposure modeling showed that pedestrian and bicyclist volume was characterized by transportation network, population, traffic generators, and land use variables. There were both similarities and differences between pedestrian and bicycle models, including different spatial scales of influence by mode. Additionally, the study quantified risk incorporating injury severity levels, frequency of victims, distance crossed, and exposure into a single equation. It was found that not all intersections with the highest number of pedestrian and bicyclist victims were identified as high-risk after exposure and other factors such as crash severity were taken into account.
