After the Resolution: Excess Commuting for Two-Worker Households in the Los Angeles Metropolitan Area

Abstract
In this study, I go beyond previous studies by distinguishing between single-worker households and two-worker households. Since there are many two-worker households in urban areas, and since these households may have more constraints than single-worker households in choosing their work or residential locations, it is more illuminating to examine commuting behavior for two-worker and single-worker households separately. I first define simple constraints on residential location choice which two-worker households may have. I then measure excess commuting for two-worker households with or without those constraints, using 1991 micro data from the Los Angeles Metropolitan area.

Abstract
Automobile driving and aggressive behavior have had an extensive association. Themes of dominance and territoriality have long been part of automobile driving, which has also involved flagrant assaultive actions. Recent episodes of roadway violence in metropolitan areas have raised community concern about aggressive behavior in driving, although common beliefs about why such violence occurs can be seen as pseudoexplanations. Various themes in the psychology of aggression are presented as they pertain to automobile driving. Convergent factors in contemporary urban life that influence roadway aggression are discussed, and it is asserted that such behavior is more prevalent than commonly recognized.

Abstract
This paper examines the possibility of negative output spillovers from public infrastructure. A model of productive public capital shows that, when input factors are mobile, public infrastructure investments in one location can draw production away from other locations. In a linear production function framework, this effect would be manifested as a negative output spillover from public capital. Using data for California counties from 1969 through 1988, such negative spillover effects are shown to exist in the case of highway and street capital. The data show that changes in county output are positively associated with changes in highway and street capital within the same county, but output changes are negatively associated with changes in highway and street capital in other counties.

Urban Form, Socio-Demographics, Attitude and Activity Spaces: Using Household-Based Travel Diary Approach to Understand Travel and Activity Space Behaviors

Abstract
Very few studies have addressed the gap in literature by examining the travel and activity patterns of travelers in developing countries to inform future land use and socio-economic planning. The major purpose of this paper is to determine the factors related with travel and activity space patterns of residents in Dhaka, Bangladesh. Based on lessons learned from a pilot study, a full study was undertaken using artificial neural network and regression. A network analyst-based shortest path network with road network buffer activity space calculation measure was used in geographic information system. Exploratory and confirmatory factor analyses were used to identify attitudinal factor dimensions. Calculated individual activity spaces were found to range from 0.08 to 10.13 square miles. Trip characteristics were found to be significant predictors of individual activity space. In case of household activity space, D variables (density, design, and destination accessibility) and household characteristics were found as the most significant. Perceived neighborhood amenities, car attachment, monetary concerns, transit preferences, perceived daily travel area and environmental concern were found to shape people’s perception. Weekend activity spaces were more compact than those for weekdays. Individual day-to-day variability was less during weekdays than on the weekend. Female and high-income respondents had smaller activity spaces.

Real-Time Trailer Scheduling for Crossdock Operations
Transportation Journal

Abstract
Abstract Crossdocks play an important role in supply chain operations. Due to the need to decrease transportation lead time to coordinate with other supply chain activities such as just-in-time, make-to-order, or merge-in-transit strategies, shortening the total transfer time at crossdocks is increasingly important. In this research, we use real-time information about freight transferring within a crossdock to schedule waiting inbound trailers in order to reduce the time freight spends in a crossdock. We use dynamic simulation models to compare the performance of several strategies. These are first-come, first-served, look-ahead, minimum processing time, and minimum total time policies. We examine these under different trailer arrival headways, crossdock layouts, and destination distributions. Our simulation results show that our time-based algorithms save more time than the first-come, first-served and look-ahead policies. In addition, these algorithms appear to result in higher service reliability and productivity.

Abstract
A radio simultaneous localization and mapping (radio SLAM) framework enabling aircraft navigation with terrestrial signals of opportunity (SOPs) is presented and experimentally validated. The framework does not assume availability of global navigation satellite system (GNSS) signals. Instead, it assumes the aircraft to have an initial estimate of its own states, after which it navigates by exploiting pseudorange measurements extracted from terrestrial SOPs, while estimating the states of the aircraft simultaneously with the SOPs’ states. Two radio SLAM frameworks are presented: (i) tightly-coupled SOP-aided inertial navigation system (INS) and (ii) utilizing a Wiener process acceleration (WPA) dynamical model for the aircraft’s dynamics instead of the INS. Results from four flight runs on a US Air Force C-12 aircraft, equipped with an altimeter and an industrial-grade inertial measurement unit (IMU), are presented. The flight runs took place over semi-urban (SU), urban (U), and rural (R) regions in California, USA; while exercising different aircraft maneuvers: holding (H), descending (D), and grid (G). Different a priori conditions of the SOPs’ positions were studied: from all unknown, to some known, to all known. In all cases, the SOPs’ clock error states (bias and drift) were unknown and estimated alongside the aircraft’s states. The results consistently demonstrated the promise of real-world aircraft navigation via radio SLAM, yielding bounded errors along trajectories of tens of kilometers. The three-dimensional (3–D) position root-mean squared errors (RMSEs) are summarized next, where N denotes the number of SOPs exploited along the trajectory: (1) SU, H, INS-SOP, N=6
