This paper illustrates the use of a technology review as part of a regional ITS Architecture development. The paper identifies market and equipment packages that are available in the market but are not defined as part of the National ITS Architecture. These packages include Pedestrian Management and Information, Surface Street Control Enforcement, Joint-Use Vehicles, Parking Facility Enforcement/Security, Automated Parking Systems, Vehicle-Based Transit Information, Advanced Commercial Vehicle Safety Advisory, Emerging Probe Surveillance Technologies, and Speed Limit Enforcement/Dynamic Speed Limits.

The results presented in this paper indicates that a review of existing ITS technologies and products is useful in identifying market packages/equipment packages that meet specific regional, local and project needs.

511 has been a successful traveler information system in the Bay Area since the telephone number was adopted and launched in 2002. Planned and unplanned events in 2007 further evolved 511 from a traveler information resource to a key tool for public outreach to be used for emergency management and response. These events were: 1) the MacArthur Maze freeway collapse, 2) planned Bay Bridge closure over the 2007 Labor Day weekend, and 3) formal 511 participation in a 2007 regional emergency preparedness exercise with Caltrans and the California Highway Patrol. This paper will review each of these events along with specific lessons learned in using 511 as a tool for public outreach during emergencies. The most significant lesson learned was that the public and policymakers who regularly rely on 511 in the Bay Area automatically expected 511 to be a resource in emergencies. Fulfilling such expectations requires considerable investment in specific tools and operational protocols.

This paper outlines the innovative work being undertaken to deliver improvements to road users
across  the  road  network,  in  the  county  of  Essex.  The  paper  shows  the  links  that  have  been
established with the private sector to make innovative use of data sources, and the work with the
County  Council’s  partnered  consultant  to  develop  sound  statistical  analysis  of  data  and  the
development of interventions to control and manage the road network. These activities combine
to form the basis of the delivery of targets agreed with central government which, when achieved,
will deliver over £3 million of reward funding to Essex County Council.

Road signs evolve as transport does. Such evolution can be traced along the
different Conventions that gave way to the 1968 Convention, aiming to be the world’s road
sign catalogue. Such general background will help us understand better the discrepancy
between first road signs, devised to be posted, and road signs that are currently missing and
should be shown on Variable Message Signs (VMS). Since 2003 the “Small Group on VMS”
has been working in order to update the 1968 Convention contents, particularly those
concerning. The work of the 2003-2006 period was presented in the 13th
World Congress on
ITS (2006). Such paper was practically equal to the final document presented to UNECE
WP.1 in the March 2008 session, and that passed to Consolidated Resolution 2 (R.E.2) finally
in the July 2008 session, after a unique modification that will be described in this paper.

The paper reports on a study comparing alternative presentations of freeway speed data on maps. The goal of the study was to inform the design of displays of real-time speed data over the Internet to the general public. Subjects were presented with a series of displays and asked to rate their preference. We looked at different choices of color (3 colors, 6 colors or a continuous range), and proposed line, sensor, and segment representations of the speed data. We also collected feedback on more complex displays such as comparison between current and "normal" speeds, and a chart of speed variation over a period of time at given locations. Finally we discuss issues of color blindness.
