This paper reviews the process followed in applying the systems engineering process to the San Mateo County Smart Corridors Program. This Program was undertaken in response to a major incident on Highway 101 which resulted in the closure of that freeway for over 24 hours. As a result, traffic diverted to the local roadways which were not able to handle the increased demand. The Smart Corridor Program is intended to address this situation when it occurs again (which is estimated to be approximately 2 to 3% of the time). Trailblazers, coordinated signals, arterial message signs and cameras will be used.

FLOW (Fast Lane On Warning) algorithms  manage traffic and reduce fuel consumption rates.
The applications presented here will cover two out of the four types of FLOW  management:
open first-encountered approaches, and inter-signal networks where traffic signals are far apart
elative to speed.. The discussion here will include algorithms for safety, emplaced readouts,
mobile readouts, adaptive robotic real time changing capabilities.  
Motorists will be able to proceed with their own individual speed assignments ranging from the
afe speed limit to a bit below half that speed depending on how long their particular open right
of way (green segment) is as well as when they arrive at the beginning of a FLOW trap.
These algorithms and associated hardware will significantly decrease fuel expenditures on an
ntersection by intersection basis, and significantly reduce pollution (NOx, particulates, O3, COx
nd so on) on an intersection by intersection basis. The algorithms presented here allow for
vehicles to remain in the high energy state. Comparisons between this high energy state vs.
raffic systems without (where most have to reaccelerate back up to the high energy state) are presented in terms of lesser fuel consumption rates and pollution reduction approximations:  
1. For an individual intersection, 2. For the LA area as an example, 3. For the Continental US.

The U.S. Department of Transportation maintains a repository of ITS lessons learned on the
ITS Lessons Learned Knowledge Resource Web site, www.itslessons.its.dot.gov.  The ITS
lessons learned are based on the experience of stakeholders from numerous ITS projects and
programs and collected from case studies, best practice compendiums, planning and design
reviews, and evaluation studies from the U.S. and abroad.  A major focus of the Web site is to
produce lessons which would benefit stakeholders across a range of ITS areas, including the
Management and Operations (M&O) of ITS programs and projects.  This paper presents a
synthesis of lessons learned about Management and Operations (M&O).  The lessons learned
on M&O discuss decision-making approaches to implement, operate and maintain
transportation facilities with the intent of optimizing system performance and improving
safety, mobility, efficiency, and reliability of the Nation's transportation infrastructure.

In order to safely reduce congestion and efficiently move people, goods, services and
information vital to the economy of both the State and City of New York, a strategy for a large, multi-stakeholder program for improved transportation safety and traffic management was developed including the build-out of a new Joint Transportation Management Center in Long Island City, NY.  This plan also specifically addressed the need to integrate existing field
devices along with emerging technologies including wide ranging data sources and automated
situation management to improve the performance of the overall traffic network.

The rapid deployment of intelligent transportation systems (ITS) field devices has heightened the need for coordinated management of such systems, usually performed at Transportation Management Systems (TMCs). Until recently, TMC operations have been focused more on monitoring and reaction to events and incidents as they occur. With the increase in field reporting mechanisms and infrastructure, a growing body of available data has made this function more difficult, while at the same time providing opportunities and challenges for expanding the role of TMCs into real-time predictive, situational awareness, and integrated corridor management functions. There is a growing need for expanded and enhanced software tools and solutions to address this expanded requirement.
