An Analysis of Port Selection

Malchow, Matthew Brian
2001

The objective of this research is to study the competition among ports. In particular we study the relation between port characteristics and port market share of maritime traffic. Maritime carriers make two primary decisions that affect ports. In the long-term, they assign vessels to routes. In the short-term, they assign each shipment to a vessel and, with that vessel, a port. In this research, we assume that vessel schedules are fixed and model the assignment of shipments as a function of the attributes that describe each port. For a carrier, some assignments are simpler than other...

New Metrics for Measuring Academic Research Outside the Ivory Tower

Levine, Kendra K.
2019

The need to demonstrate the value of research programs is critical for funding sustainability, particularly in the 21st century where research funding is rarely guaranteed beyond the life of a single project. After the great economic crash of 2008 many research programs have also diversified their funding portfolios, which means cultivating new relationships with funders and potentially different objectives of research projects. Measuring the impact of academic research outside academia is critical to providing a holistic view of a research program, but the methods to do so are still being...

Impacts of Shared Mobility

Shaheen, Susan, PhD
Cohen, Adam
2018

Shared mobility modes have reported a number of environmental, social, and transportation-related impacts. Several studies have documented the reduction of vehicle usage, ownership, and vehicle miles traveled (VMT). Cost savings and convenience are frequently cited as popular reasons for shifting to a shared mode. Shared modes can also extend the catchment area of public transit, potentially playing a pivotal role in bridging gaps in existing transportation networks and encouraging multi-modality by addressing the first-and-last mile issue related to public transit access (1). Shared...

Shared Mobility Policies for California

Shaheen, Susan, PhD
Cohen, Adam
2018

In recent years, economic, environmental, and social forces have quickly given rise to the “sharing economy,” a collective of entrepreneurs and consumers leveraging technology to share resources, save money, and generate capital. Shared mobility—the shared use of a vehicle, bicycle, or other low-speed travel mode—is an innovative transportation strategy that enables users to have short-term access to a transportation mode on an as-needed basis. Business-to-consumer services, such as Zipcar and car2go, and peer-to-peer carsharing and shared ride services, such as Getaround, Turo, Lyft, and...

From Elevated Freeway to Linear Park: Land Price Impacts of Seoul, Korea's CGC Project

Kang, Chang Deok
Cervero, Robert
2008

Freeways and other high-performance roadway investments have long been considered vital to the economic well-being of metropolitan areas. Empirical research shows that limited-access, grade-separated freeway systems increase a region’s economic productivity by lowering transportation costs, a factor input to economic production (Aschauer, 1990; Boarnet, 1997). Past studies also reveal that urban land markets capitalize the benefit of proximity to freeway interchanges, especially for non-residential uses and in areas experiencing worsening traffic conditions (Gillen, 1996; Boarnet, 1997;...

Urban Development on Railway-Served Land: Lessons and Opportunities for the Developing World

Cervero, Robert
2020

Under the right conditions -- serious traffic congestion, a permissive regulatory environment, and frequent and reliable transit services -- rail transit investments can powerfully shape cities and regions. Rail transit’s city‐shaping powers are due to market forces and policy interventions. By enhancing accessibility (the ability of those living, working, or shopping rail near stops to quickly reach desired destinations) rail services increase the value and desirability of properties in and around stations. Market pressures by themselves rarely produce transit oriented development. To...

Bus Rapid Transit Impacts on Land Uses and Land Values in Seoul, Korea

Cervero, Robert
Kang, Chang Deok
2009

More and more cities are turning to Bus Rapid Transit (BRT) as a way of cost-effectively expanding public transit services to help relieve traffic congestion, reduce carbon emissions, and increase mobility options for the poor. Because of the inherent flexibility advantages of rubber-tire buses – e.g., unlike rail systems, the same vehicle that functions as a line-haul carrier can also morph into a neighborhood feeder -- BRT is especially suited for many lower density and non- CBD settings.Some of the most advanced and widely heralded BRT services today are found in Latin America, such as...

Accessible Cities and Regions: A Framework for Sustainable Transport and Urbanism in the 21st Century

Cervero, Robert
2005

This paper examines both the principle and analytical possibilities of accessibility as a platform for advancing sustainable transport and urbanism in coming years and decades. Experiences with accessibility planning are first reviewed, followed by a discussion of various measurement and analytical contexts. The paper then uses various policy contexts and case settings to probe the use of accessibility for addressing contemporary urban and regional transportation and land-use themes, including: inter-modal comparisons of job accessibility and their implications for social equity and...

A Dynamic Congestion Pricing Strategy for High-Occupancy Toll Lanes

Jang, Kitae
Chung, Koohong
2010

High Occupancy Toll (HOT) lanes are emerging as a solution to address the underutilization of High Occupancy Vehicle (HOV) lanes and also means of generating revenue for state department of transportation. This paper proposes a method for dynamically determining the HOT toll price in response to the changes in traffic condition and documents procedures for estimating parameters needed for the proposed pricing strategies: revenue maximization and delay minimization. The proposed strategies have been applied to 14-miles of freeway segment in the San Francisco Bay Area, and the findings show...

Low Income Childhood Pedestrian Injury: Understanding the Disparate Risk

Johnson, Emily
Geyer, Judy A
Rai, Nirmeet
Ragland, David R
2004

A leading cause of death and injury to children is being struck by a motor vehicle. A disproportionate number of injured child pedestrians are of low socioeconomic status. The relationship between socioeconomic status and pedestrian injury is poorly understood. The existing literature is limited by the lack of pedestrian exposure data, a common measure of risk, and a clear conceptual framework for the interaction between socioeconomic status and pedestrian injury. Another issue is the limited availability of injury data. This paper proposes a model for understanding child pedestrian...
