• Analyzing Human Activity Patterns Using Cellular Phone Data: Case Study of Jinhe New Town in Shanghai, China
  Abstract: In the urbanization process of big cities in China, the rise of satellite towns, the migration of manufacturing and the relocation of residents to the suburban areas have accelerated the separation between workplace and residence and brought enormous changes to the activity patterns of Chinese cities. In this paper, we propose a novel and data-driven method of extracting individuals¡¯ daily activities and identifying ¡°anchor points¡± (home and workplace) from mobile phone data and survey data, and apply it to the Jinhe new town. People in study area are classified into three groups, and use time-geographic concept to depict individual activity pattern of each group. Furthermore, we focus on the residents with obviously separated home and workplace caused by suburbanization. For representing the cluster of these people¡¯s activities in space-time, kernel density estimation is used to detect the intensity in space-time. The activity density profile facilitates finding the spatio-temporal characteristic of the demand deriving from suburban residents. The study shows that mobile phone data allows analyzing human activity pattern in space-time at very detailed scale but also require other data resources for comprehensiveness and visualization of all people across the city.

• Quality Control of Toll Data for Mobility Performance Measures on Jingshen Expressway in China
  Abstract: China is experiencing an unprecedented growth in transportation development. The enclosed Chinese toll system provides an opportunity for the toll data to be used for monitoring mobility performance. However, quality control of such toll data is challenging. The toll data from the Jingshen Expressway in China was analyzed and assessed for mobility performance evaluation. Quality control criteria were developed to filtering out erroneous data and off-network stops. The mobility performance measures, namely, Travel Time Index, Congestion Duration, and Planning Time Index were calculated for the Jingshen Expressway network. The research shows the toll data which is essentially Origination and Destination (OD) data in nature can be used for overall mobility performance evaluation with sufficient quality control. However, the limitation of such data is that it is based on OD pairs. The mobility performance was assumed to be consistent within an adjacent OD pair. It is suggested that the toll data combined with spot speeds from other data sources, such as fixed-point sensors or surveillance camera, be used for more in-depth study.

• Public-Private Partnership in Traveler Information Provisions: Case Study of a Developing Country
  Abstract: Developing countries make a larger contribution to global transportation related problems than developed countries, and they also suffer more acutely from limited budgets. Traveler Information Provisions (TIP) assist commuters in making better travel decisions, thereby leading to increased mobility and more efficient travel. At the same time, shrinking public funding has made the public-private partnership more attractive. Seemingly there are opportunities for Public-Private Partnerships (PPP) in TIP in developing countries. Nonetheless, the use of PPP to fund public projects in the developing countries is in its infancy, and the issues related to this do not receive adequate attention in the literature. In this study, we investigated PPP’s opportunities in TIP in the case of a developing country; Tehran, Iran. We first studied the factors contributing to TIP effectiveness by analyzing commuters’ behavioral changes in response to currently broadcasted Radio Traffic Information (RTI). The analysis was conducted using Multi-Nominal Logit and Nested Logit models. From this analysis, we identified commuter characteristics, trip purpose, and the content of RTI information as contributing factors which direct us to some potential markets and strategies for investment in TIP. We then reviewed the literature to identify some challenges and opportunities of PPP in past experiences as well as special regional constraints. According to the modeling results and the literature review we outlined some business models for PPP in TIP. Some key findings are (i)data integration and customization is essential, (ii)with respect to purchasing behavior, the market has to be stratified into commuter and corporate markets, and (iii)the market for GPS based services is promising.

• Low-Mass Urban Microcars for Emerging Market Megacities
  Abstract: For rapidly growing vehicle markets, small, low mass vehicles show promise. New regulatory norms are needed that take into account the differing operating environments and demands of these vehicles. We explore the potential for such vehicles to meet the demands of consumers and transportation systems in emerging markets, particularly in dense megacities, initially as commercial last-mile transportation and more broadly for private automobile consumers. We propose a regulatory template for these “Urban Microcars” that considers potential energy, emissions, and safety impacts, and borrows features from the Low Speed Vehicle (LSV) category in the U.S. and the L5e Motor Tricycle and L7e heavy Quadricycle norms in the European Union.

• Vehicle Ownership in Middle-Class Indian Households: Mobility in Mumbai
  Abstract: As median household incomes rise in India, discretionary spending in the consumption basket is going up, along with increases in transportation budgets. Middle-class households are investing in private vehicles such as motorized two-wheelers (TWs) and cars. This is further adding to negative externalities such as congestion, emissions, higher accident rates, noise pollution, etc.This paper explores the drivers of TW and car ownership in middle-class Indian households. The analysis is conducted using a household travel survey from the Greater Mumbai Region (GMR), where the unit of analysis is the household (N=38,346). Using a discrete choice modeling framework, where the choice set is households having (i) no vehicles, (ii) only TW/s, or (iii) at least one car, the results indicate that utility from vehicle ownership increases with –• Life cycle variables: kids in the household, married status of primary wage earner.• Socio-demographic variables: housing unit characteristics (number of rooms, apartment/independent housing type), primary wage earner’s characteristics (college education, employment status, male), persons in the household.• Other variables: per capita household income, distance from a railway station, primary wage earner’s urban periphery work location, population density at primary wage earner’s work location.These findings illustrate the sensitivity of vehicle ownership not only to life cycle and socio-demographic variables, but also to land use variables such as density, proximity to transit, and jobs-housing locations in the city-region. Policies that encourage both in-city and urban periphery node development, with strategic higher development densities, along with provision of public transportation options are indicated from this research.
