The tool was required not only to deliver accurate forecasts with a small development budget but also to operate independently of other models, run on a platform that could be freely distributed without special software licenses, and provide user-friendly access to planners in multiple agencies with varying levels of technical skill. For these requirements to be satisfied, an incremental nested logit mode choice model was developed that pivoted off static exports of trip tables from the Association of Monterey Bay Area Governments' existing four-step travel model. GPS traces collected from smartphone users in the region were analyzed to estimate a path-size logit route choice model, and the California Household Travel Survey was used to estimate a scaling coefficient on the best route utility. The model was implemented in an Adobe ActionScript graphical user interface. After the user edits the bicycle network in the user interface, new bicycle levels of service are skimmed, and new shares for each mode are calculated from their original shares in the no-build alternative and the change in the bicycle level of service. Finally, the emissions reduction is estimated on the basis of the distance and average speed of the vehicle trips replaced by bicycle travel. The result is an accurate, fast, freely distributable, user-friendly tool that is consistent with the forecasts produced by the four-step model.", "publicationTitle": "Transportation Research Record: Journal of the Transportation Research Board", "publisher": "", "place": "", "date": "November 3, 2014", "volume": "2430", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "124-132", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Transportation Research Record: Journal of the Transportation Research Board", "DOI": "10.3141/2430-13", "citationKey": "", "url": "http://trrjournalonline.trb.org/doi/abs/10.3141/2430-13", "accessDate": "2016-09-29T17:16:17Z", "PMID": "", "PMCID": "", "ISSN": "0361-1981", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "trrjournalonline.trb.org (Atypon)", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "California Household Travel Survey" }, { "tag": "non-NREL authored" } ], "collections": [], "relations": {}, "dateAdded": "2016-09-29T17:16:17Z", "dateModified": "2016-09-29T17:16:17Z" } }, { "key": "544CA68Z", "version": 265, "library": { "type": "group", "id": 671423, "name": "TSDC_citations", "links": { "alternate": { "href": "https://www.zotero.org/groups/tsdc_citations", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/671423/items/544CA68Z", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/tsdc_citations/items/544CA68Z", "type": "text/html" } }, "meta": { "createdByUser": { "id": 250494, "username": "tsandberg", "name": "Tami Sandberg", "links": { "alternate": { "href": "https://www.zotero.org/tsandberg", "type": "text/html" } } }, "creatorSummary": "Salon", "parsedDate": "2015-10", "numChildren": 0 }, "data": { "key": "544CA68Z", "version": 265, "itemType": "journalArticle", "title": "Heterogeneity in the relationship between the built environment and driving: Focus on neighborhood type and travel purpose", "creators": [ { "creatorType": "author", "firstName": "Deborah", "lastName": "Salon" } ], "abstractNote": "Global concern about fossil fuel use and associated environmental externalities has led many governments to consider actions that encourage their residents to drive less. This research uses empirical analysis of travel survey data to estimate the relationship between built environment characteristics and vehicle miles traveled (VMT) in California. The work improves upon past research in two key ways. First, it employs a novel approach to control for residential self-selection, categorizing neighborhoods into types and using these as the alternatives in a predictive model of neighborhood type choice. Second, it focuses on exploring and understanding heterogeneity in the relationship between the built environment and VMT across two dimensions – neighborhood type and travel purpose.\n\nThe results show that VMT sensitivity to built environment characteristics does depend on both neighborhood type and the purpose of travel, in ways that are intuitive but had not previously been estimated. This calls into question the usefulness of prior research that provides only single point estimates of the relationships between travel choices and the built environment. Though these relationships may be small on average, this work shows that for certain trip types and in certain neighborhood types, the built environment is strongly related to travel choices.", "publicationTitle": "Research in Transportation Economics", "publisher": "", "place": "", "date": "October 2015", "volume": "52", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "34-45", "series": "Sustainable Transportation", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Research in Transportation Economics", "DOI": "10.1016/j.retrec.2015.10.008", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0739885915000529", "accessDate": "2016-09-29T17:15:29Z", "PMID": "", "PMCID": "", "ISSN": "0739-8859", "archive": "", "archiveLocation": "", "shortTitle": "Heterogeneity in the relationship between the built environment and driving", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "California Household Travel Survey" }, { "tag": "non-NREL authored" } ], "collections": [], "relations": {}, "dateAdded": "2016-09-29T17:15:29Z", "dateModified": "2016-09-29T17:15:29Z" } }, { "key": "JWP6NP5P", "version": 263, "library": { "type": "group", "id": 671423, "name": "TSDC_citations", "links": { "alternate": { "href": "https://www.zotero.org/groups/tsdc_citations", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/671423/items/JWP6NP5P", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/tsdc_citations/items/JWP6NP5P", "type": "text/html" } }, "meta": { "createdByUser": { "id": 250494, "username": "tsandberg", "name": "Tami Sandberg", "links": { "alternate": { "href": "https://www.zotero.org/tsandberg", "type": "text/html" } } }, "creatorSummary": "Wang", "parsedDate": "2015-05", "numChildren": 0 }, "data": { "key": "JWP6NP5P", "version": 263, "itemType": "thesis", "title": "How Does Built Environment Affect Cycling?

Empirical research suggests that the relationship between job accessibility and employment outcomes differ across income groups, but no research has investigated the difference or explored which income groups benefit the most from job accessibility improvements. This research fills the gap by examining six income groups in the Los Angeles metropolitan area. Results show that job accessibility affects the employment status of medium-to-low income groups (household income between US$25,000 and US$75,000). For the lowest-income group (household income lower than US$25,000), owning a car significantly improves their chances to be employed, but job accessibility has no effect. On the other hand, higher job accessibility is associated with shorter commuting distance for the other five income groups, but not for the lowest-income group. These results suggest that transportation and land use policies need to address the specific needs of distinct population groups and underscore the importance of spatial access for the middle-class,

consensus on key issues, compliance with relevant laws and regulations, and improvements in the congestion, air quality, and safety performance of the transportation system. Some performance areas lend themselves well to operationalization while others do not. One area that has received comparatively little study is the assessment of a plan's impacts on environmental justice and social equity. Although research on regional planning usually emphasizes larger metropolitan areas and agencies, these issues are especially relevant in smaller regions where planners lack the capacity for innovation and careful analysis. Further, the transit services on which disadvantaged populations depend are often lacking or non-existent in less-populated regions. Understanding how planners in these locations undertake social equity-related analyses and providing suggestions for improvement is thus an important endeavor. While prior work has assessed whether, and to what extent, equity objectives are included in plans, there are few detailed investigations of the key analytical choices that shape equity outcomes. This paper fills this important research gap, providing such an analysis of existing practice in a largely rural region in California, the San Joaquin Valley, as well as recommendations for future analyses aimed at improving the consistency between equity analyses and the real-world impacts of transportation plans.", "publicationTitle": "Transport Policy", "publisher": "", "place": "", "date": "November 2016", "volume": "52", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "46-54", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Transport Policy", "DOI": "10.1016/j.tranpol.2016.07.004", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0967070X16304292", "accessDate": "2016-09-29T16:56:44Z", "PMID": "", "PMCID": "", "ISSN": "0967-070X", "archive": "", "archiveLocation": "", "shortTitle": "Planning for transportation equity in small regions", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "California Household Travel Survey" }, { "tag": "non-NREL authored" } ], "collections": [], "relations": {}, "dateAdded": "2016-09-29T16:56:44Z", "dateModified": "2016-09-29T16:56:44Z" } }, { "key": "MEQSSGQX", "version": 242, "library": { "type": "group", "id": 671423, "name": "TSDC_citations", "links": { "alternate": { "href": "https://www.zotero.org/groups/tsdc_citations", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/671423/items/MEQSSGQX", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/tsdc_citations/items/MEQSSGQX", "type": "text/html" } }, "meta": { "createdByUser": { "id": 250494, "username": "tsandberg", "name": "Tami Sandberg", "links": { "alternate": { "href": "https://www.zotero.org/tsandberg", "type": "text/html" } } }, "creatorSummary": "California Environmental Protection Agency-Air Resources Board", "parsedDate": "2015-06", "numChildren": 0 }, "data": { "key": "MEQSSGQX", "version": 242, "itemType": "report", "title": "Technical Evaluation of the Greenhouse Gas Emissions Reduction Quantification for the San Luis Obispo Council of Governments' SB 375 Sustainable Communities Strategies", "creators": [ { "creatorType": "author", "name": "California Environmental Protection Agency-Air Resources Board" } ], "abstractNote": "", "reportNumber": "", "reportType": "", "institution": "", "place": "", "date": "June 2015", "seriesTitle": "", "seriesNumber": "", "pages": "", "DOI": "", "ISBN": "", "citationKey": "", "url": "http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.731.1808&rep=rep1&type=pdf", "accessDate": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "California Household Travel Survey" }, { "tag": "non-NREL authored" } ], "collections": [], "relations": {}, "dateAdded": "2016-09-29T16:54:10Z", "dateModified": "2016-09-29T16:54:48Z" } }, { "key": "973I4J7V", "version": 240, "library": { "type": "group", "id": 671423, "name": "TSDC_citations", "links": { "alternate": { "href": "https://www.zotero.org/groups/tsdc_citations", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/671423/items/973I4J7V", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/tsdc_citations/items/973I4J7V", "type": "text/html" } }, "meta": { "createdByUser": { "id": 250494, "username": "tsandberg", "name": "Tami Sandberg", "links": { "alternate": { "href": "https://www.zotero.org/tsandberg", "type": "text/html" } } }, "creatorSummary": "McLaren et al.", "parsedDate": "2016-06", "numChildren": 0 }, "data": { "key": "973I4J7V", "version": 240, "itemType": "journalArticle", "title": "CO2 emissions associated with electric vehicle charging: The impact of electricity generation mix, charging infrastructure availability and vehicle type", "creators": [ { "creatorType": "author", "firstName": "Joyce", "lastName": "McLaren" }, { "creatorType": "author", "firstName": "John", "lastName": "Miller" }, { "creatorType": "author", "firstName": "Eric", "lastName": "O’Shaughnessy" }, { "creatorType": "author", "firstName": "Eric", "lastName": "Wood" }, { "creatorType": "author", "firstName": "Evan", "lastName": "Shapiro" } ], "abstractNote": "The emission reduction benefits of EVs are dependent on the time and location of charging.

EV mobility is a unique and inherent feature of the V2G system. However, the inter-relationship between EV mobility and DRM is not obvious. In this paper, we focus on the exploration of EV mobility to impact DRM in V2G systems in smart grid. We first present a dynamic complex network model of V2G mobile energy networks, considering the fact that EVs travel across multiple districts, and hence EVs can be acting as energy transporters among different districts. We formulate the districts' DRM dynamics, which is coupled with each other through EV fleets. In addition, a complex network synchronization method is proposed to analyze the dynamic behavior in V2G mobile energy networks. Numerical results show that EVs mobility of symmetrical EV fleet is able to achieve synchronous stability of network and balance the power demand among different districts. This observation is also validated by simulation with real world data.", "publicationTitle": "IEEE Transactions on Industrial Informatics", "publisher": "", "place": "", "date": "February 2016", "volume": "12", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "79-90", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1109/TII.2015.2494884", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1551-3203", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "IEEE Xplore", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "California Household Travel Survey" }, { "tag": "non-NREL authored" } ], "collections": [], "relations": {}, "dateAdded": "2016-09-29T16:52:26Z", "dateModified": "2016-09-29T16:52:26Z" } }, { "key": "UFB7B9JT", "version": 238, "library": { "type": "group", "id": 671423, "name": "TSDC_citations", "links": { "alternate": { "href": "https://www.zotero.org/groups/tsdc_citations", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/671423/items/UFB7B9JT", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/tsdc_citations/items/UFB7B9JT", "type": "text/html" } }, "meta": { "createdByUser": { "id": 250494, "username": "tsandberg", "name": "Tami Sandberg", "links": { "alternate": { "href": "https://www.zotero.org/tsandberg", "type": "text/html" } } }, "creatorSummary": "Razeghi et al.", "parsedDate": "2016-07", "numChildren": 0 }, "data": { "key": "UFB7B9JT", "version": 238, "itemType": "journalArticle", "title": "Episodic air quality impacts of plug-in electric vehicles", "creators": [ { "creatorType": "author", "firstName": "Ghazal", "lastName": "Razeghi" }, { "creatorType": "author", "firstName": "Marc", "lastName": "Carreras-Sospedra" }, { "creatorType": "author", "firstName": "Tim", "lastName": "Brown" }, { "creatorType": "author", "firstName": "Jack", "lastName": "Brouwer" }, { "creatorType": "author", "firstName": "Donald", "lastName": "Dabdub" }, { "creatorType": "author", "firstName": "Scott", "lastName": "Samuelsen" } ], "abstractNote": "In this paper, the Spatially and Temporally Resolved Energy and Environment Tool (STREET) is used in conjunction with University of California Irvine – California Institute of Technology (UCI-CIT) atmospheric chemistry and transport model to assess the impact of deploying plug-in electric vehicles and integrating wind energy into the electricity grid on urban air quality. STREET is used to generate emissions profiles associated with transportation and power generation sectors for different future cases. These profiles are then used as inputs to UCI-CIT to assess the impact of each case on urban air quality.\n\nThe results show an overall improvement in 8-h averaged ozone and 24-h averaged particulate matter concentrations in the South Coast Air Basin (SoCAB) with localized increases in some cases. The most significant reductions occur northeast of the region where baseline concentrations are highest (up to 6 ppb decrease in 8-h-averaged ozone and 6 μg/m3 decrease in 24-h-averaged PM2.5). The results also indicate that, without integration of wind energy into the electricity grid, the temporal vehicle charging profile has very little to no effect on urban air quality.

and travel patterns", "creators": [ { "creatorType": "author", "firstName": "Akshay", "lastName": "Vij" } ], "abstractNote": "This study proposes a model of individual daily activity and travel patterns that captures the concurrent influence of the individual’s lifestyle and modality style on each of the many decisions that together constitute her daily activity and travel pattern. Modality styles are defined as lifestyles built around the use of a particular travel mode or set of travel modes (Vij et al., 2013). They are hypothesized to influence all dimensions of individual and household travel and activity behavior. Transportation policies and infrastructural investments seeking to change existing patterns of travel and activity behavior are frequently undermined by deeply entrenched lifestyles and modality styles built around the use of the car. As Ryuichi Kitamura (1988) wrote in his seminal paper on lifestyles and travel behavior, “To deal with the challenge to urban transportation, one must first recognize that congestion is not the problem, but merely a symptom. The true problem is the life-style to which Americans aspire; the American dream is to live in a suburban single-family house on a half-acre lot with a three-car garage. If this is the root of the urban transportation problem, then obviously a fundamental solution to the issue of congestion cannot be reached without addressing the question of life-style.” Travel demand models constitute an important component of the planning and policy-making process. Forecasts from travel demand models are regularly employed to determine the required capacity that new infrastructure must satisfy, and to facilitate the economic, environmental and social impact assessments that usually accompany the debate on how to allocate funds between competing initiatives. The field of travel demand analysis has progressed far beyond the aggregate models that defined the profession for much of the last century. Research during the eighties and nineties culminated in the activity-based model, a disaggregate model of individual and household travel and activity behavior which formulates the demand for travel as a function of the demand for various activities, predicting which activities are conducted where, when, for how long, with whom and using what mode of travel. Though the shift towards disaggregate models of decision-making has been seen as a significant step forward, activity-based models currently in practice continue to be deficient in their inability to account for the existence of different modality styles, and the subsequent influence exerted by these differing modality styles on multiple dimensions of individual and household travel and activity behavior. The objective of this study is to develop and test an econometric model framework that recognizes the influence exerted by modality styles on all facets of an individual’s daily activity pattern. Using the model of daily activity patterns embedded within the San Francisco Chained Activity Modeling Process (SF-CHAMP), the state-of-the-art activity-based model developed for the San Francisco County Transportation Authority (SFCTA), as our point of departure (Cambridge Systematics, 2002), we build on recent advances in discrete choice analysis in the sub-domains of taste heterogeneity, choice set generation, preference endogeneity and simultaneous choice models to develop a latent class choice model (LCCM) of daily activity patterns. Our framework extends the LCCM framework proposed by Vij and Walker (2014), first applied to study the influence of modality styles on travel mode choice behavior, to include the additional influence of modality styles on other dimensions of behavior, such as time of day and destination choice, that together make up an individual’s daily activity pattern. For example, in the context of time of day choice, different modality styles may be characterized by differences in the times considered when deciding when to travel and differences in the sensitivity to accessibility measures when making that decision. In the context of destination choice, different modality styles may be characterized by differences in the places considered when deciding where to travel and differences in the sensitivity to land use variables when making that decision. These individual differences, when jointly modeled, should offer a greater understanding of differences in lifestyles and modality styles underlying existing patterns of behavior. Figure 1 illustrates the model framework in greater detail. Modality styles are represented as latent classes, and the class membership model predicts the probability that an individual has a particular modality style as a function of socioeconomic variables, such as employment and household income, and long-term travel and activity decisions, such as residential location and level of car ownership. Conditioned on the class, or modality style, that the individual belongs to, the class-specific choice model predicts the probability that the individual chooses a particular daily activity pattern as a function of the attributes of the transportation and land use system. The class-specific choice model may further be decomposed into a series of sequentially nested logit models, analogous to SF-CHAMP’s daily activity pattern model. Lower dimensions, such as trip mode choice and trip destination choice, are conditioned on higher dimensions, such as full-day pattern choice and tour time of day choice; outcomes to higher dimensions are formulated as a function of logsums feeding upwards from lower dimensions. Heterogeneity in the decision-making process is captured by allowing taste parameters and choice sets for each choice dimension to vary across the classes. The framework is tested using single-day travel diary data retrieved from 17,199 individuals belonging to 8,081 households residing in the nine-county San Francisco Bay Area, collected as part of the larger California Household Travel Survey 2012. Early estimation results indicate the existence of seven distinct modality styles, or classes, in the sample population. Different modality styles differ from one another in terms of their socioeconomic composition, their predisposition towards different alternatives and their sensitivity to different attributes of the transportation and land use system. For example, one of the seven classes, labeled Suburban Drivers, comprises 13.7% of the sample population and consists largely of adults belonging to high-income households with kids living in single-family homes with high levels of car ownership. Suburban Drivers do not consider any travel modes other than the car when deciding how to travel, are unlikely to frequent mixed-use walkable neighborhoods, and are immune to congestion and other service-related factors when deciding what time of day to travel. Another class, labeled Multimodals, comprises 6.0% of the sample population and consists largely of single employed adults belonging to small households with no kids living in rented apartments, often with a carshare membership. Multimodals consider all travel modes when deciding how to travel, prefer to visit mixed-use neighborhoods (though they too do not prefer walkable neighborhoods), and are sensitive to congestion and other service-related factors when deciding what time of day to travel. In summary, the LCCM framework is able to paint a far more vivid picture of lifestyle and modality style typologies that exist in the Bay Area than would be possible using a more traditional activity-based model, such as the SF-CHAMP. Ongoing work is refining some of these estimation results and exploring implications for policy analysis. The model framework developed by this study represents a paradigmatic transition from activity-based models of travel and activity behavior to lifestyle-based models of travel and activity behavior. Our findings should serve as a proof-of-concept for how other activity-based model systems, such as the Comprehensive Econometric Micro-simulator of Daily Activity-Travel Patterns (CEMDAP) developed by Bhat et al. (2004), or the Coordinated Travel - Regional Activity Modeling Platform (CT-RAMP) developed by Parsons Brinckerhoff (Davidson et al., 2010), may analogously be extended to incorporate the influence of lifestyles and modality styles, with the intention of facilitating the kind of analysis that Kitamura thought necessary two-and-a-half decades ago.
