Personal Mobility

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.

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.

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 focus of this report began with the initial task of identifying and recommending potential
alternatives for the replacement of the functionality that is provided by a Javelin video matrix switch.  This task was triggered by an end-of-life announcement from the switch manufacturer.  While this announcement underscored the need to address the issue in a timely manner, the planned 100-200% increase in the number of required video input and output ports resulted in the more urgent need to upgrade this design.

The Minnesota Department of Transportation (Mn/DOT) is assessing new traffic control
strategies for lane closures in work zones. The traditional work zone performs adequately
as long as the traffic demand does not exceed the capacity of the single lane closure.
When congestion occurs, dangerous travel characteristics develop due to incompatible
driver behaviors and presumptions about correct merging procedures.
The objective of this project was to develop, test, and evaluate a traffic control system
that dynamically incorporates the best aspects of both the Early and Late Merge systems.
The Dynamic Late Merge System (DLMS) is a fully automated system that utilizes
Doppler radar and Remote Traffic Microwave Sensors (RTMS) to collect data on the
current state of traffic. Under predefined traffic conditions, Changeable Message Signs
(CMS) display lane-use instructions to drivers in the section of roadway preceding the
lane closure.
Implementation of the DLMS was very brief.  During this time, a noticeable change was
observed in driver behavior. Drivers were beginning to utilize the lanes in accordance
with the instructions on the CMS as the construction period progressed.  Unfortunately,
drivers never continually approached the merge point to take turns merging.  This first
deployment in a series did yield some useful knowledge about sign placement and data
collection for use in future operations of the DLMS.  This initial deployment was the first
step in assessing the overall effectiveness of a Dynamic Late Merge System.
