Management of traffic in large, active, and congested areas can be assisted by a number of
technologies including adaptive traffic control systems, variable message signs (VMS),
efficient incident management, and closed circuit television (CCTV) systems.
Typically each of these technologies is managed using different systems, each with their own
separate operator interfaces. This leads to clutter on operator workstation screens in traffic
control centres, and makes viewing the overall status of the network as a whole difficult.
The Traffic Management Interface System, TMIS, developed by the Traffic Systems Branch
of the Roads and Traffic Authority (RTA) of NSW, Australia, is intended to provide a
platform that combines real time monitoring and control of the above technologies and others
into a uniform, spatially oriented view of the traffic network and allows traffic operators to
respond to events in the network.
This paper describes the TMIS philosophy, the systems it currently interfaces to, and the
services it provides to the traffic engineers and operators.

The Florida Department of Transportation (FDOT) has begun implementation of the FDOT’s
first managed lanes, known as 95 Express. The 95 Express Project was implemented by
converting the existing High Occupancy Vehicle (HOV) lane, adding a lane, and creating the two managed lanes or High Occupancy Toll (HOT) lanes. Phase 1A of the project was open to
tolling on December 5, 2008. The FDOT D6 Transportation Management Center (TMC) played
an active role in supporting the ITS/Toll Equipment/Operations Team. This paper presents the
FDOT D6 TMC’s approach for TMC Control Room Operations, Incident Management, and
Dynamic Pricing. In addition, preliminary operational analysis was conducted to evaluate how
tolling changed travel patterns along the I-95 corridor, assessment of the dynamic pricing, and
the preliminary benefits of I-95 Express Lanes.

Using traffic control devices and communications equipment to monitor and control arterials and
freeways has brought with it new challenges and a demand for new skills. Many systems and
equipment procurements have occurred without clear traceability between agency needs and
potential solutions. A common result has been that agency needs are not satisfied. Such a
procurement environment, where no direct traceability (or a weak association) between agency
needs and provided solutions, often leads to project cost overruns, late delivery and even failed
projects. Applying systems engineering methodologies and incorporating ITS Standards that
contain user needs, requirements, and design solutions into the procurement process will mitigate
the risk of not satisfying agency needs. This paper presents a description of the problem, and a
description of a life-cycle process that uses systems engineering methods proven to satisfy
agency needs when deploying ITS Standards. This paper also provides lessons learned and
suggestions for success, and benefits of these methods. Examples of how the life-cycle process
and the systems engineering methods were applied are taken from the NTCIP 1203 Dynamic
Message Sign (DMS) version 02 Standard Implementation Project, sponsored by USDOT and
VDOT/VTTI.

ITS Projects include the application of data processing and communications to surface transportation.  ITS Project Risk is a failure to satisfy the needs of project stakeholders (users, operators and maintainers), or an unexpected delay and/or cost to complete the project. A Consensus based ITS Architecture is one that all stakeholders agree will meet their ITS needs. This paper explains how a policy of developing, maintaining, and using a regional ITS architecture to plan ITS projects, and a systems engineering process to design, build, and test an ITS project accelerates deployment, while reducing the risk of ITS project failure.

Florida Department of Transportation (FDOT) is implementing the first Ramp
Signaling (RS) system along the I-95 corridor within Southeast Florida as part of an overall long-term strategy of integrated initiatives to improve the safety, throughput and reliability of mobility within this region. As a relatively low-cost traffic management technique, Ramp signals have been used to alleviate congestion due to bottlenecks and mainline traffic flow being disrupted by entering platoons in the past decades. This paper documents the deployment of the first RM system in South Florida. In this paper, the project is first overviewed, followed by the description of the RS system (devices, software and hardware) and the system operation, then various implement challenges and the solutions to address these challenges are presented. The practical experience embodied by this project will benefit the new deployment of RS system in the future.
