LOS ANGELES--(BUSINESS WIRE)--Three new members representing the Central Basin Municipal Water District and the city of Glendale were seated yesterday on the board of directors of the Metropolitan Water District of Southern California. Bell Gardens City Councilmember Pedro Aceituno and real estate broker Phillip D. Hawkins will serve as Central Basin’s representatives on Metropolitan’s 38-member board, joining Glendale City Councilmember Zareh Sinanyan as the city’s representative. Aceituno replaces Leticia Vásquez-Wilson, who had served on the Metropolitan board since February 2015 and previously from February 2013 to July 2014. Hawkins returns to Metropolitan’s board—where he served from July 2014 to February 2015 and from June 2003 to August 2009. He succeeds Robert Apodaca, who represented Central Basin since February 2013 as well as from June 2003 to August 2009. Sinanyan follows Laura Friedman, who had represented the city since February 2009. First elected to the Bell Garden City Council in 1999, Aceituno is the city’s longest-serving elected official. He was elected to the Central Basin board last November, representing Bell Gardens, Downey, Montebello, Pico Rivera, West Whittier-Los Nietos and unincorporated areas of Los Angeles County. Aceituno was recognized by Central Basin in 2007 for his work in making Bell Gardens the first city in the region to embrace a city-wide water conservation program. He helped transform the city into a "California Friendly City" model by integrating key water-saving measures at public parks and facilities. A life-long Bell Gardens resident, Aceituno is the city’s representative to the Sanitation Districts of Los Angeles County, Southeast Area Animal Control Authority, Southern California Association of Governments, Greater Los Angeles County Vector Control District, Eco-Rapid Transit and the Gateway Cities Council of Governments. Re-elected to his fifth term on Central Basin’s board last November, Hawkins currently serves as board president. His Central Basin district consists of the cities of Artesia, Bellflower, Cerritos, Hawaiian Gardens, Lakewood, Paramount and Signal Hill. A real estate broker since 1977, Hawkins has opened several businesses, including Realty World in Bellflower, Herbert Hawkins Realty, also in Bellflower, Century 21 in Norwalk and the Dean Company. Hawkins, a Cerritos resident, was elected to the California Assembly in 1994, representing the 56th Assembly District until 1996. During his Assembly term, he was chairman of the Committee on Housing and Community Development and vice chair of the Committee on Budget, and served as a member of various other committees. An attorney with his own Glendale law practice, Sinanyan was elected to the City Council in April 2013 and served as mayor from April 2014 to April 2015. The founding chair of the Glendale Economic Development Corp., he currently serves as Glendale Housing Authority chair, secretary of the Burbank/Glendale/Pasadena Airport Authority, and vice chair of the Eco-Rapid Transit Authority. Born in formerly Soviet Armenia, Sinanyan earned his bachelor’s degrees in political science and history at UCLA and his juris doctorate from the University of Southern California Law School. While in law school, Sinanyan interned for Justice Earl Johnson of the California Court of Appeal, where he helped draft appellate opinions for a number of cases ranging from criminal to civil matters. He also clerked and worked for the U.S. Securities and Exchange Commission’s Enforcement Division. Note to editors: Digital photographs of the new Metropolitan directors are available upon request. The Metropolitan Water District of Southern California is a state-established cooperative of 26 cities and water agencies serving nearly 19 million people in six counties. The district imports water from the Colorado River and Northern California to supplement local supplies, and helps its members to develop increased water conservation, recycling, storage and other resource-management programs.

This paper established a research framework for administrative divisions based on functional areas analysis. Firstly, data related to natural conditions, history, socio-economy, transportation and information across Shaoxing are anchored to several small geographical units -blocks or small towns, which forms the basis to identify the interdependence between the units from different levels, and provides the proof of spatial flexibility for urban diversity. Subsequent analysis was concentrated on the division of functional areas through factor analysis and cluster analysis, which provides scientific foundation for the re-organization of the functional areas. On the basis of the research framework, with Shaoxing city as an example, the study indicates that the geographic, socio-economic, transportation and information connections between current administrative districts in Shaoxing have already broken through the limitation of administrative demarcation. Administrative divisions based on functional areas should be enhanced to further stimulate regional development. On the one hand, this approach ensures the accordance between administrative divisions and functional areas, which will facilitate the regional integration and socio-economic development; on the other hand, the administrative divisions dispel the shielding effect of segmentation between natural system and socio-economic system, which would exert positive influence for Shaoxing on promoting the development of surrounding areas. In all, this paper concludes that the administrative divisions based on the analysis of the function areas has exceptional importance and significance on the fast proceeding of physical environmental and socio-economic development. © 2015, Science Press.

In this paper an estimation is made of a joint household-level model of the number of vehicles owned by a household, the vehicle type choice of each vehicle, the annual mileage on each vehicle, and the individual assigned as the primary driver for each vehicle. A version of the proposed model system currently serves as the engine for a household vehicle composition and evolution simulator, which itself has been embedded in the larger Simulator of Activities, Greenhouse Emissions, Energy, Networks, and Travel (SimAGENT), an activity-based travel and emissions forecasting system for the Southern California Association of Governments planning region.

This paper focuses on the interrelationships between ICT, activity fragmentation and travel behaviour. The concept of fragmentation relates to how activities are spatiotemporally reorganized, by subdividing activities into smaller components that are then performed at different times and/or locations, in connection with ICT use. The association between ICT, activity fragmentation and travel relationships remains uncharted. Based on a two-day Dutch communication-activity-travel diary different associations between ICT use, paid work spatiotemporal fragmentation indicators and frequency of travel are specified and tested with Path Analysis Modelling accounting for sociodemographic and land use factors. The results demonstrate that the interrelationships between fragmentation, ICT and travel are quite complex. ICT and fragmentation apparently have a reciprocal relationship with mobile ICT use influencing the degree of spatial fragmentation whereas the usages of sedentary ICT are influenced by the degree of temporal fragmentation. Person-ICT attributes and ICT use mediate the participation in non-work activities, and can replace work and non-work travel. Fragmentation reduces work trips but at the same time restricts non-work personal travel possibilities and can reallocate time for leisure activity and travel. © 2014 Elsevier Ltd.

"Accessibility," defined as the ease (or difficulty) with which opportunities for activity can be reached from a given location, can be measured with the cumulative amount of opportunities from an origin within a given amount of travel time. These indicators can be used in regional planning and modeling efforts to integrate land use and travel demand, and an attempt should be made to calculate these indicators for the smallest geographic area. The primary objective of this paper is to illustrate the creation of realistic space-sensitive and time-sensitive block-level accessibility indicators to track the availability of opportunities. These indicators support the development of an activity-based travel demand model by Southern California Association of Governments to provide second-by-second and parcel-by-parcel modeling and simulation. The indicators also provided the base information for mapping opportunities of access to 15 types of industries at different times during a day. The indicators and their maps were defined for the entire region of Southern California through largely available data that included the Census Transportation Planning Package, Dun & Brad-street postprocessed data, detailed highway networks and travel times from the four-step regional models, and arrival and departure times of workers by industry.

Automated performance-monitoring systems take in intelligent transportation system sensor data in real time, archive them, and analyze them. These systems are needed to help local agencies identify problem areas, develop improvement plans, and perform before and after evaluations on the impacts of traffic management changes. Research performed in the past few years has demonstrated the utility of these systems for local transportation agencies, particularly for evaluating signal progression quality. However, acquiring the critical data items for existing arterial intelligent transportation systems-signal phase event information-is often a practical challenge because the configuration of the existing system of most arterial systems does not record or communicate signal phase events to a central location. As a solution to that problem, this paper documents an approach to estimate signal phase data with in-pavement vehicle sensors, a data source that is generally available from arterial systems. On many arterial systems, these sensors frequently communicate data from the field to a central traffic management center. The goal of this paper was to make recent arterial progression quality research implementable by developing a method to gather signal phase event data in a way that would be practical for most local transportation agencies, given their existing arterial systems. Two proposed methods were tested on a year's worth of data from a 2-mi arterial corridor in Carson, California. Results showed that sensor data from central traffic management centers could be used to develop accurate measurements of signal phase events when coupled with timing plans.

This paper develops and estimates a multiple discrete continuous extreme value model of household activity generation that jointly predicts the activity participation decisions of all individuals in a household by activity purpose and the precise combination of individuals participating. The model is estimated on a sample obtained from the post census regional household travel survey conducted by the South California Association of Governments in the year 2000. A host of household, individual, and residential neighborhood accessibility measures are used as explanatory variables. The results reveal that, in addition to household and individual demographics, the built environment of the home zone also impacts the activity participation levels and durations of households. A validation exercise is undertaken to evaluate the ability of the proposed model to predict participation levels and durations. In addition to providing richness in behavioral detail, the model can be easily embedded in an activity-based microsimulation framework and is computationally efficient as it obviates the need for several hierarchical sub-models typically used in extant activity-based systems to generate activity patterns. © 2013 Springer Science+Business Media New York.

Southern California is the largest international trade gateway in the United States. The region generates enormous activity involving the movement of local and domestic goods. Given the expected growth in international trade and movement of domestic goods, significant growth in truck volumes and rail traffic to facilitate the reliable movement of goods and to support economic growth is anticipated in the region. As the movement of goods is a major contributor to local and regional environmental issues such as air pollution and health risk, a regional priority is not only to mitigate the environmental impacts of the system involving the movement of goods but also to ensure that, pursuant to Title VI of the Civil Rights Act, equity exists in the distribution of environmental benefits and burdens from federally funded programs involving the movement of goods and projects. Therefore, to prevent disproportionately high and adverse environmental effects and health risks from affecting minority and low-income populations as a result of the movement of goods, the Southern California Association of Governments analyzed the environmental justice implications of the system involving the movement of goods included in the regional transportation plan. The objective of this paper is to identify the minority and low-income populations affected, to analyze their spatial distributions along major truck corridors and freight rail corridors, and to address the environmental justice implications of the system involving the movement of goods in Southern California.

The population-employment (P-E) relationship in the multicounty region has not been considered enough to document, although numerous future regional policy issues affecting local areas have required producing a technically sound and politically acceptable projection of population or employment with the US metropolitan planning organizations. This study intended to answer two key questions based on the county-level data sets of P-E ratio for Southern California. First, we investigated whether the Southern California region has been or will be experiencing any convergence in the P-E ratio gap among counties in the long-term perspective. Second, we tested to understand whether a vector autoregression (VAR) approach contributes to developing the county-level P-E ratio projection model for the region. Finally, we validated the VAR projections using independent data sets. The quantified information in the present study can help regional and subregional stakeholders encourage and initiate an effective discussion about the future of the region. © 2013 Springer-Verlag Berlin Heidelberg.

Due to the high cost, low response rate and time-consuming data processing, few Metropolitan Planning Organizations can afford collecting household travel survey data as frequently as needed. This paper presents a methodology to simulate disaggregate and synthetic household travel survey data by examining the feasibility of the spatial transferability of travel data. Households are clustered into several homogeneous groups to identify the distributions of their travel attributes. These distributions are then transferred to similar groups in other regions. Furthermore, updating methods are suggested and developed to calibrate the parameters of the transferred distributions for the application area. A user friendly software is developed that facilitates the entire process. To validate the model, a synthetic population for the state of New York, excluding the New York City, is generated by a two-stage population synthesis procedure. Then, travel attributes of each household are simulated and by linking the generated travel data to the synthetic population, a synthetic household travel dataset is generated for the application context. Finally, using a new validation dataset from the application area, comparisons against the simulated data are made to examine the effectiveness of the simulation process. © 2010 Elsevier Ltd.
