Improving Bay Area Rapid Transit (BART) District Connectivity and Access with the Segway Human Transporter and Other Low Speed Mobility Devices

Access to transit stations is a significant barrier to transit use in many urban regions. Parking during peak hours is often limited, and many individuals are only willing to walk about a quarter mile to transit stations (Cervero, 2001). While there are some effective feeder services (e.g., shuttles) that help extend the range of transit access, these systems are limited because of fixed routes and schedules. A number of strategies have recently been implemented to improve transit access and transit use, including bicycles, electric bicycles, carsharing, and personal neighborhood electric...

Evaluation of Incorporating Hybrid Vehicle Use of HOV Lanes

Brownstone, David
Chu, Lianyu
Golob, Tom
Nesamani, K.S.
Recker, Will
2008

This report presents a method to investigate the operational and environmental effects of the policy of allowing qualified single-occupancy hybrid vehicles to use dedicated High-Occupancy Vehicle (HOV)/carpool lanes in California.. The method combines the traditional planning method with microscopic simulation modeling. The planning method is used for demand estimation and analysis and the microscopic traffic simulation modeling method is used for accurate measures of the system. The study employs a microscopic traffic simulation model that is capable of evaluating the HOV/hybrid system...

Highway Electrification And Automation Technologies - Regional Impacts Analysis Project: Phase Iii: Impacts Analysis Results

Scag
Path
1993

This report presents the third, and final, phase of the Highway Electrification and Automation Technologies Regional Impacts Analysis Project (HE&A). The focus of Phase III report is the assessment of regional impacts associated with application of roadway electrification, and automation technologies to selected freeway sections in the Southern California region.

Planning and Accommodating the Micromobility Revolution and Its Impact on Public Health

Quistberg, Alex
Rodriguez, Daniel
2024

Micromobility has grown immensely over the past decade, encompassing both public shared systems and private ownership, and, as Burford et al. have found, a surge in user injuries and deaths has accompanied the growth. Micromobility refers to the use of small vehicles, such as bicycles and scooters, that are either human powered or electric. These vehicles are ideal for short trips—although electric-powered micromobility has expanded the potential distance range.

Fuel Saving Achieved in the Field Test of Two Tandem Trucks

Browand, Fred
McArthur, John
Radovich, Charles
2004

The fuel consumption of two tandem trucks is recorded for truck spacings of 3, 4, 6, 8, and 10 meters. The trucks are linked by means of an electronic control system, and are operated on an unused runway at Crows Landing, California. Fuel consumption data is averaged while traveling in both directions over the same central strip of runway to cancel the effect of runway slope and to partially cancel the effect of wind. The average fuel consumption saving to be achieved by tandem operation varies from about 11% at 3-4 meters spacing to about 8% at 8-10 meters spacing.

Task A-2: Implementation and Management of Electronic Roadway Tolling: Lessons from Successful Cases

Kalauskas, Rebecca
Taylor, Brian D.
Iseki, Hiroyuki
2009

Over the past decade road pricing has moved from the drawing board to practice in projects large and small around the world. But while interest in and experience with electronic roadway tolling is on the rise, political acceptance is not yet widespread and standard models of implementation and management have yet to evolve. Accordingly, this report examines a variety of road pricing projects– some that were smoothly implemented, and others that encountered significant obstacles along the way. Based on these cases and a thorough review of the literature, we draw lessons to guide future...

TASK A-3: Examining the Linkages between Electronic Roadway Tolling Technologies and Road Pricing Policy Goals

Demisch, Alexander
Iseki, Hiroyuki, PhD
Taylor, Brian D.
2009

The surge of road pricing projects in the U.S. and around the globe over the past fifteen years has been enabled by a set of new communication and transportation technologies. There is currently a wide array of technical configurations ranging from systems based on “tried and true” short-range radio communications to experimental systems relying on global positioning satellites. These technologies provide for a more efficient collection of simple tolls, and also facilitate a movement toward more dynamic, variable user fees.In this study, we provide a comprehensive literature review of...

Roadway Powered Electric Vehicle Project Track Construction And Testing Program Phase 3D

Systems Control Technology, Inc.
1994

This report covers the construction and testing of a Roadway Powered Electric Vehicle (RPEV) proof-of-concept system. The test facility was built at the University of California Richmond Field Station. The facility has a 700-foot test track and an operational 35-passenger RPEV. The report contains an introduction to the concept of RPEV and discusses the following aspects of the project: systems engineering and design, vehicle, facilities, testing, related RPEV research, and control circuits.
