This paper describes the work and results of the second phase of research sponsored by the Federal Highway Administration (FHWA) initiated to study the relationship between traffic activity and ambient PM2.5 concentrations. The study, entitled “Estimating the Transportation Contribution to Particulate Matter Pollution”, had the objective of performing a correlation analyses on particulate matte...
Increasing number of urban trips and inappropriate use of motor vehicle fleet, especially private passenger cars with its unwanted consequences, including excessive increase in fuel consumption, makes it necessary to think about appropriate strategies and policies for planning and management of energy resources. This paper tries to identify fuel management strategies and policies in urban trans...
Combined bus rapid transit and buses in a dedicated lane (CBBD) is measure that (BRT) operators implement to reduce overlapping routes between BRT fixed-route buses. The CBBD can combine the passengers of both systems on same route, which helps increase passenger demand for BRT, fuel consumption emissions from utilizing exclusive lanes combined route. However, could affect some terms either los...
Getting informed on the characteristics of provincial transportation could be helpful in regional economic planning. This paper tries to describe the situations in provincial economic sectors through data analysis and location quotient in order to identify the necessary characteristics of transportation. It also attempts at examining transportation status of the province and comparing its chara...
Considerably less research has been done on modeling freight demand with disaggregate discrete models than on modeling passenger demand. The principal reason for this imbalance is the lack of freight demand data. Freight demand characteristics are expensive to obtain and are sometimes confidential. This paper analyzes the freight demand characteristics that drive modal choice by means of a larg...
OBJECTIVE The aim of this study is to examine whether a persons' most frequently used mode of transportation is associated with life-space mobility and whether the association differs between persons with or without walking difficulties. METHOD Life-space mobility was measured with the Life-Space Assessment in 848 community-dwelling men and women aged 75 to 90 years. Six separate mobility gro...
Many studies have been conducted to analyze efficiency of railways for different countries. However, these studies have mainly focused on quantitative aspects of railway transportation and quality has been neglected. In this paper three new data envelopment analysis (DEA) models are presented. The first model is solved for assessing quality of passenger railway services in 71 countries of t...
Crew scheduling can be defined as the problem of assigning a group of workers (a crew) to a set of tasks. The crews are typically interchangeable , although in some cases different crews possess different characteristics that affect which subsets of tasks they can complete. Crew scheduling problems appear in a number of transportation contexts. Examples include bus and rail transit, truck and r...
