This paper summarises some of the achievements of information strategy work currently
conducted in the Directorate of Traffic Operations (DTO) of Transport for London (TfL),
United Kingdom. In particular the paper highlights a comprehensive system and data
audit, an intelligence requirement capture exercise, and a network analysis methodology.

The main goal of Intelligent Transportation Systems (ITS) is to improve the overall efficiency of transportation systems by using modern computers, communication, and data processing technologies without substantial capacity additions to the network (Tarko and Rouphail 1997). Surveys show that, next to safety and security, traffic information is among the services most desired by motorists (Orski 2001). Travelers have an implicit expectation that high-technology services have equally high-technology content.

In the UK, buses carry more passengers annually than any other public transport (PT) mode (5 billion compared to rail’s 2 billion27). And they share the road with a growing number (over 30M) of vehicles for private transport and freight. There are congestion problems in almost every major town and city and this impacts directly on the ability of bus operators to adhere to bus schedules which reduces the overall service levels for the passengers. Part of the solution to the problem of congestion is satellite tracking of the buses to provide Real-Time Information (RTI) to passengers thereby allowing them to make informed and intelligent decisions about their travel.

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.

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.
