Dynamic Ridesharing

Elizabeth Deakin, Karen Trapenberg Frick, and Kevin Shively

Most cars can carry at least four passengers, but the average auto occupancy rate for all trips in the US is only 1.6 persons. Because all the empty seats in cars represent our greatest source of untapped transportation capacity, promoting ridesharing is of considerable interest. Government agencies across the country employ ridesharing programs both to provide transportation at low cost and to reduce traffic congestion and the other costs of solo driving.

Introduction: Transportation Technologies for the 21st Century

Elizabeth Deakin

New technologies are transforming the way we plan, design, build, and operate transportation systems. Transport agencies use them to count traffic, detect crashes, collect tolls and fares, and manage transit operations and traffic signal systems. Travelers depend on traffic condition reports, electronic maps, on-board vehicle performance monitors, real-time transit arrival information, and a host of other services that did not exist a generation ago. Some of us are already driving hybrid vehicles or commuting in buses powered by hydrogen or biofuels. For the future, we all are counting on additional advances in transportation technology, not just to get us where we want to go, but also to reduce greenhouse gases, improve air quality, and support economic development.

Intelligent Transport Systems: Linking Technology and Transport Policy to Help Steer the Future

Elizabeth Deakin, Karen Trapenberg Frick, and Alexander Skabardonis

If you’ve seen an electronic message sign along the highway that tells you how long it will take to get downtown or to the airport, or paid your toll or your parking fees with an electronic tag, or ridden a bus that triggered the traffic lights to turn green as it approached them, then you have experienced some of the benefits of Intelligent Transportation Systems (ITS)—an umbrella term for a variety of new technologies and operations methods for highways and transit. Other on-the-ground ITS applications are less visible to the average traveler, but every bit as useful: they help traffic managers detect and respond to accidents promptly, handle the extra traffic that special events generate, and help state workers safely plow snow on mountain roads in blinding snowstorms.

Introduction

Elizabeth Deakin

Transportation planners and engineers often focus on specific areas of expertise, such as particular modes of transport, or air quality effects of transportation. Increasingly, however, Californians are reminded that such focused specializations, while valuable, are insufficient by themselves. Current efforts to meet stringent greenhouse gas reduction targets while accommodating growth and counteracting economic downturn show just how complex and interconnected urban development issues are. The emerging paradigm is one that integrates transportation planning into a broader metropolitan development strategy.

California Futures: Accommodating Growth In an Era of Climate Change and Rising Fuel Prices

Elizabeth Deakin

Sometime between 2025 and 2030, California's population will reach 50 million. During this same period, the state (and indeed the entire world) must find effective ways to substantially reduce greenhouse gas (GHG) emissions in hopes of slowing and reversing climate change. California has committed to such reductions in SB 32 and Executive Order S-3-05; the state has pledged to reduce GHG to 2000 levels by 2010 (11 percent below business-as-usual), to 1990 levels by 2020 (25 percent below business-as-usual), and to eighty percent below 1990 levels by 2050.

The Challenge of Urban Transportation in California

Elizabeth Deakin and Robert Cervero

As California grows, increased travel from more households, business activity, and goods movement will surely increase greenhouse gas emissions, lead to more congestion and air pollution, and damage ecosystems and neighborhoods—unless we change the basics of travel in California. We need to take action now to deliver a sustainable transportation system that provides the mobility and accessibility necessary for a prosperous economy, and to find ways of doing so that also assure a healthy environment, social equity, and a high quality of life. Here are some ideas for managing, improving, and reworking our urban transport systems that are proven best practices and, with legislative leadership, could be more widely utilized.
