The City of Lakewood, Managing Engineer Mr. Jim Richey, is in the process of a two phase,
three year long project to upgrade the existing traffic signal control system and
communications network to support IP-based communications. The approach taken for this
upgrade allowed for the system to remain functional throughout the phases which will span
three years.

This paper addresses in general the FTA’s current emphasis on transit circulators, and in that light the need for an analysis methodology and modeling tools that address technology focused transit circulator studies. As a focused topic, the paper approaches the alternatives analysis  requirements in terms of the functional ITS elements used by transit circulator technologies. The paper also includes a discussion of the nature of transport systems suitable for circulation system applications in urban centers and the diverse technology options that are available for transit circulator applications, including at-grade and aerial transit system alignments/technologies. To analyze the different ways in which these alternative technologies interact with other systems within the built environment – in particular the emulation of the traffic signal system and the associated operations of the traffic and pedestrian systems – special modeling tools are described that accomplish a true “apples-toapples” comparison between alternatives.

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.
