Toward Automation of Mobility Measures in Portland, Oregon
Intelligent transportation systems (ITS) provide the surveillance infrastructure for both advanced transportation management and advanced traveler information. Having shifted toward a much more intensified data rich environment, it is now possible to consider automatically generating mobility measures as part of an overall traffic management and information system. Many regions use inductive loop detector technology for measuring key traffic parameters such as flow, occupancy and average speed. Mobility-related measures can be produced from these data including vehicle miles traveled, vehicle hours traveled, average speed, travel time, delay and other nationally accepted parameters that measure transportation system performance. The Portland, Oregon metropolitan region is developing a system to automate the generation of mobility measures using inductive loop detector data. In this paper, we describe a rigorous, microscopic validation process that has been developed to validate the inductive loop detector data using ground truth video. In addition, we present several methods for converting the validated data to useful visualizations which are helpful for transportation management and operations.

The Use of IPASS to Improve Mobility and Safety Through Traveler Information
Increasing awareness levels of the average motorist to the ever changing traffic
conditions encountered on an interstate highway system prepares them for their trip, thus
improving the mobility of people and goods regionally and nationally. Knowledge of
traffic conditions and travel times in advance of travel provides the motorist with
valuable information and allows them an option that is unavailable to the uninformed
motorist. Alert motorists can react with confidence to known situations or decide to take
an alternate route. The net result, informed motorists react better to situations that are
known in advance and in turn, can reduce or eliminate potential crashes or gridlock.

Integrated Single-windows, e-Port Tech to improve Seaport Transportation Mobility and Efficiency
This paper describes how the e-Port, e-Government, and e-Logistics strategies have been
rapidly development, increasingly accepted, and implemented successfully in emerging
economies throughout the world. For example, in Ukraine, a Web-based e-Business resource
is used to access the export regulations, commercial licensing & application information, and
network integration for electronic coordination among all ministries associated with the export
review. In Bulgaria, a national network to enable e-Government initiatives and e-Government
Architectural Governance model. In Belarus and Kazakhstan, the intergovernmental networks
has been used to promote electronic exchange and coordinate export applications, and
enhanced information sharing among State Customs Services, Export Control Services, and
other coordinating ministries through the e-Logistics Applications.

Evaluation of the Benefits and Costs of ATMS
This paper presents an assessment of the methods and parameters used in existing sketch
planning tools to evaluate ATIS. The paper also discusses the development and implementation of a methodology to estimate the benefits and costs of ATIS, as part of a travel demand forecasting modeling environment. Default values for the benefit and cost parameters used in the evaluation of ATIS are recommended based on analyzing ATIS-related databases and based on an extensive review of existing reports on the subject. The results from an evaluation case study indicate that phone-based and web-based ATIS deployments in a small region can be shown to be an effective solution from a benefit-cost point of view.

Minnesota's VII for Safety, Mobility and User Fee
The proliferation of Vehicle Infrastructure Integration (VII) technology throughout the
nation has led to the State of Minnesota developing their first VII deployment. Currently,
the Minnesota Department of Transportation (Mn/DOT) has two consultants under
contract to begin work on Phase I of their efforts. A technical program management team
will develop the concept of operations in Phase I, while the evaluation team will develop
the evaluation goals and plans. Phase II will include all implementation efforts as well as
the final project evaluation. Minnesota is currently focusing on three different
applications for their VII demonstration: an enhanced traveler information system, an invehicle
signing system, and a mileage-based user fee system.
