Integrated Framework for Fine-Grained Transportation and Air Quality Analyses
Abstract：This talk presents and demonstrates, through a case study, an integrated and holistic modeling framework for analyzing fine grained transportation activities and resulting vehicle emissions, air pollution and health impacts. The modeling framework consists of six modules, i.e., economics and land use model, activity-based travel demand model, dynamic traffic assignment model, mobile source emissions simulator, air dispersion model, and health exposure assessment. This talk will focuses on the methodology and processes that integrate all the modules into one cohesive framework. The integration approach is useful to support transportation policy analysis especially transportation conformity analyses required by law in the United States
Modeling Land Use, Bus Ridership and Air Quality: A Case Study of Chicago Bus Service.
Abstract：Public transit accessibility and ridership are affected by neighboring environment along the transit lines. This paper investigates the relations between neighborhood features and bus ridership and emissions of the Chicago Transit Authority (CTA) bus lines. A mixed regression model of bus emissions/ridership model is created to quantify the direct relations with both internal bus operation indicators such as route length and number of stops and external factors including neighborhood land use and population socio-demographics. In Chicago, there are a large number of serviced urban Black neighborhoods with low population in vicinity of bus routes, poor connectivity to transit, and low transit users to work in general, resulting in high per unit ridership bus emissions (grams/ridership) for routes servicing those areas. As the city and the transit agency have been making great effort to increasing bus ridership in those neighborhoods, more collaborative work must be done by the city, the local planning agencies and the transit agency to improve accessibility to bus service.
Economic and Environmental Analyses of Urban Delivery Consolidation Strategies
Abstract：Among new, innovative city logistics strategies, delivery cooperation has received increasing academic and practical attention mostly in Europe and Japan. The idea is to establish cooperation among the suppliers, carriers and the customers through Urban Consolidation Center (UCC), a public facility usually located at the city boundary; with proper consolidation of loads and routing, the goods are then sent to the customers in the urban area with cleaner vehicles and less vehicle miles traveled (VMT). Although creating a terminal increases the operating cost at the facility, it may be compensated by reducing VMT with the right economies of scale, stocking cost at the customer end, and emissions and congestion in urban area. In this talk, I will explore strategies which will make UCC an economic and environmental attractive delivery option in the US cities. We formulate the delivery problem using the Continuum Approximation (CA) method and illustrate it through a hypothetical case study.
