Custom Interface Builder Palettes For Advanced Driver Interface Rapid Prototyping

Moore, David W.
1993

This manual provides a brief introduction to four classes of software objects developed to help a user create and test interfaces using these objects in the Interface Builder application environment. The Knob, Dial, Alert Light, and Map object classes presented here represent the beginnings of a software library of virtual interface objects designed to support a rapid prototyping environment for advanced interfaces as described in "Rapid Prototyping of Advanced Driver Interface Systems."

Institutional, Organizational and Market Aspects of Successful ITS Deployment: A Case Study Analysis

Conroy, Patrick
2003

This research follows on a previous study to explore key aspects of successful Intelligent Transportation Systems (ITS) deployment within existing institutional, organizational and market environments. The researcher developed three additional case studies of successful ITS deployment in the U.S. and Europe, and revisited one case from the previous work. Results from literature searches and surveys were analyzed, and findings on institutional, organizational and market factors are presented. Key words: ITS, deployment, institutional, value, business models, benefits, highway capacity

Integrated Traffic and Communications Modeling Environment for ATMIS

Varaiya, P.
Walrand, J.
Wu, F.F.
Polydoros, A.
Sylvester, J.
1997

The aims of this MOU were to create an integrated environment for modeling traffic flow, sensor data, and the communications infrastructure for ATMIS. The research plan was to build separate tools for measuring the communications requirements of ATMIS traffic, modeling a mobile radio communications environment, and communications network design, and then to integrate them in an object-oriented environment from which one could also access existing or new road traffic simulation packages.Section 1 of the report presents a framework for estimating the vehicle-roadside communications...

Driving Intelligence Replacement in a Decision-Oriented Deployment Framework for Driving Automation

Tsao, H.-S. Jacob
Ran, Bin
1996

What some human drivers have done wrong has been blamed for much of the problem associated with the current highway systems. For example, driver inattention, fatigue and other human errors have often been cited as major sources of safety hazard on current highways and human capabilities as major limitations on current highway capacity. Such human deficiencies and the pervasive urban traffic congestion have motivated the concept of Automated Highway Systems (AHS). The fundamental objective of AHS is to achieve user and societal benefits through replacing human driving by automated machine...

Database Environment for Fast Real-Time Simulation of Urban Traffic Networks with ATMIS

Jayakrishnan, R.
Sheu, Phillip
Wang, Taehyung
Xu, MinHua
2000

This project develops the environment for using the ATMIS simulation software developed under previous PATH projects (MOUs 39, 84, and 170) for real-time traffic simulation and scenario analysis with feedback from the real urban network. keywords: traffic simulation, databases, object-relation databases, dynasmart

Identification and Prioritization of Environmentally Beneficial Intelligent Transportation Technologies: Modeling Effort

Young, Troy
Sperling, Daniel;
Shaheen, Susan
1999

In 1996, California Partners in Advanced Transit and Highways (PATH) commissioned a project team led by the Institute of Transportation Studies, University of California at Davis with the Claremont Graduate School to undertake a review of the environmental impacts of Intelligent Transportation Systems (ITS). The objectives of this project were to: 1) review previous qualitative and quantitative environmental assessments of ITS, from both field operational tests and modeling studies; 2) review the regulatory and policy contexts which encompass ITS; 3) develop a modeling framework suitable...

Identification And Prioritization Of Environmentally Beneficial Intelligent Transportation Technologies

Shaheen, S.
Young, T.
Sperling, D.
Jordan, D.
Horan, T.
1998

This report presents an literature review on the energy and environmental impacts of Intelligent Transportation Systems (ITS) technologies, a presentation of the development of deployment/modeling scenarios, and a description of the modeling effort. It looks at the current polity context and regulatory arena in which ITS technologies will be deployed. It also provides scenarios and market penetration estimates developed to form the basis of modeling efforts with the INTEGRATION model.

Trav Info Evaluation ( Technology Element ) Traveler Information Center ( TIC ) Study: Operator Interface Analysis - Phase III

Miller, Mark
Loukakos, Dimitri
1998

TravInfo is a Field Operational Test of advanced traveler information systems for the San Francisco Bay Area, sponsored by the Federal Highway Administration (FHWA). The project involves a public/private partnership which seeks to compile, integrate and broadly disseminate timely and accurate multi-modal traveler information through commercial products and services. The public sector component centers on the Traveler Information Center (TIC), which collects and integrates both static and dynamic traveler information. The TIC began operations in September 1996 and will operate as an FOT...

Modeling IVHSEmission Impacts. Volume 1: Background Issues And Modeling Capabilities

Guensler, Randall
Washington, Simon
Sperling, Daniel
1994

This paper examines the potential air quality impacts of Intelligent Vehicle Highway Systems (IVHS) upon important emission-producing vehicle activities and those parameters that affect emission rates. Important emission relationships are identified, a framework for comparative analysis is developed, and the general relationships between IVHS technology bundle characteristics and vehicle emission impacts are examined. The primary IVHS emission-related impacts that this project addresses are associated with changes in the average speed and operating mode (acceleration, deceleration, cruise...
