The SCOOT Urban Traffic Control system is now operating in over 200 cities and towns
worldwide. Since the first system was installed there has been a continuous program of
research and development to provide new facilities which take into account new technology
and meet the requirements of the traffic manager. This paper reports on a new version
SCOOT MC3 which has recently been released. SCOOT has been modified to use timestamped
data which should allow for small time delays in communications between the UTC
software and Outstation Transmission Units (OTU) whilst maintaining the excellent level of
traffic control. This should increase the range of communication options available and in
particular allow the use of some of the newer data communications systems which are packet
based. A congestion supervisor has been developed which should afford the operator a better
understanding of the congestion occurring in the network. This should enable the limited
resources within local authorities to be used efficiently and facilitate the use of the extensive
congestion management tools available in SCOOT. Other new developments effect how
SCOOT operates in providing bus priority and in controlling puffin pedestrian crossings.

With the rapid growth of the motor vehicles in Beijing, the traffic jam situation is
aggravated constantly. The function of SCOOT traffic signal control system has not
gradually adapted to the actual traffic demand. After analyzing and researching the
current situation and problems of existing SCOOT systematic operation in Beijing,
the construction objects are put forward according to the traffic characteristics and
system control characteristics within Second Ring Road in Beijing. Through choices
of investigating route and intersections and investigating date and by using the
method of before and after, a good effect is got and The operation status of the traffic
has got very great improvement after the system was implemented, demonstrating the
SCOOT system superiority of the single point control.

The original Marey graph, published in 1885, has become a frequent example of innovative

design in data visualization. It plots a French train timetable on a time-space diagram, intuitively

depicting the paths of trains throughout the day. These graphs continue to be used in transitrelated

applications such as the Google Transit Feed Specification (GTFS) Schedule Viewer. This

paper repurposes the original Marey graph for use in transit performance measurement by adding

schedule adherence and passenger load information. APC data preprocessing steps are described

and technological issues related to the development of the visualization are discussed. Finally,

this paper demonstrates how the Marey graph enables quick visual identification of vehicle

performance trends across space and time.

We are at a point in the life of the Intelligent Transportation Systems (ITS) movement
that poor, non-responsive and inadequate support by our traffic and transportation
management centers (TMC), traffic control centers (TCC) and traffic operations centers
(TOC) will not be tolerated. We can no longer hide behind the mantra that we are just
learning the game. If we are to assume our rightful place in the area of providing quality
support to our citizenry we must be able to quickly provide the results of accurate and
timely data collection, possess an efficient and through data analysis capability,
demonstrate an ability to make cogent and informed decisions, rapidly disseminate the
results of these decisions and subsequently, check on the results of the decisions. In short,
we are expected to have all of the aspects of a decision support system in place, be ready
to provide enhanced traffic management capabilities as well as meet the emerging
requirement to provide efficient and timely support to the Principal Responding Agencies
(PRA) on the hook to respond to the full range of weather-related/natural disasters, man-
caused incidents and events and military operations.

Iteris staff members have been involved in several design/build ITS projects over the last
several years. These projects have included the Michigan DOT Design/Build/Warranty
Project which involved 148 miles of Detroit area freeways. Included were more than 140
closed circuit television (CCTV) cameras, 43 changeable message signs (CMS), 1200 loops,
ramp metering and a mix of fiber optics and wireless communications. Other projects have
included the implementation of traffic signal systems for Westminster, California and
Fontana, California. Based on these experiences and others, a great deal of experience has
been gained in implementing ITS projects in a design/build procurement environment.
Among the lessons learned is the need to establish a true partnership among all parties; the
preaward effort can be very demanding on all parties; staff needs can fluctuate greatly, and
there is the need for all parties not to approach these types of projects as typical
design/bid/build projects.
