Personal Mobility

Over the past five years, there has been a revolution in the way that airports can present
ground transportation options to their passengers. Tools and media that would have been
unimaginable just a decade ago are now readily available to the airport manager interested in
creating better public mode ground transportation strategies to her/his airport. The paper
examines the development of new and evolving information technology to bring airport
ground access information and ticketing options to the traveler. The paper concludes that
most major metro areas have sophisticated advanced traveler information systems in
operation, that most airports try to disseminate good ground access information, but there is
very little functional integration occurring between the two. The paper is based on, and
provides an update to, work undertaken for the Airport Cooperative Research Program (1)
and for the I-95 Corridor Coalition (2).

In September of 2007 the Missouri Department of Transportation (MoDOT) introduced the
Driving Edge initiative, an umbrella of strategies that provides highway information to the
traveling public before they begin their trip, along the way and around the clock. The
program is comprised of three main elements: an Online Traveler Information Map, Around
the Clock Customer Service and permanent Dynamic Message Signs (DMS) on rural sections
of their interstate system. This technical paper briefly outlines one component of that
initiative, the statewide rural deployment of 48 Dynamic Message Signs on our most traveled
interstate corridors.

The City of Milwaukee is deploying an Advanced Parking Guidance System (APGS) to collect
available parking data from downtown parking facilities and provide this real-time information to
the traveling public and system operators. This information will then be distributed to a number
of partner agencies, including the Wisconsin Department of Transportation (WisDOT), the
Milwaukee Police Department, and the Milwaukee County Sheriff’s Department. Parking
availability information will be provided to the traveling public through static and dynamic
wayfinding signs located throughout the central business district, freeway dynamic message
signs, a real-time public Internet website, an XML data source, and a telephone line. The project,
which consists of two phases, is scheduled for completion by the end of 2009. In the future the
City hopes to deploy the APGS throughout the CBD and ultimately expand the system to full
time operation.

In 1999, the French Ministry of Transport launched a significant program of experimentation and evaluation in order to assess the effects of different kinds of intelligent speed adaptation systems in terms of acceptance by the drivers and effectiveness of speed reduction in their daily trips. The LAVIA (Limiteur s’Adaptant à la VItesse Autorisée) has been tested, in the Yvelines (France) according to three variants : advisory, voluntary limited and mandatory limited. An experiment carried out over one year on a sample of hundred drivers using twenty equipped vehicles, allowed recording a huge amount of data in naturalistic driving conditions. Important results on safety were depicted in several papers. Besides the initial objectives of the projects which were restricted to acceptance and safety impact studies, it appears that a key aspect, in line with sustainable mobility stakes, concerns LAVIA impact on fuel consumption. In this paper, after a will brief recall of LAVIA objectives, technical aspects and results, we will present the results of a new statistical analysis study which focuses on the respective impact of the three variants of the system on fuel consumption.Guillaume Saint Pierre and Jacques Ehrlich

Intelligent Transportation Systems (ITS) are targeted at the study of (1) how
information can be used to improve the safety and mobility of the driver, and (2) the potential
impact of information to reduce fuel consumption and greenhouse gas emissions. This paper
focuses on the latter, i.e. the economical and environmental impact of ITS.  We examine the
following three questions: (1) What are the incentives and disincentives that may change
automobile consumption and commute choice?  In particular, we look at historical data on
gasoline prices and price as a disincentive to discourage fuel consumption; (2) What do
education and information campaigns do to help promote fuel consumption reduction?  After
surveying various education programs to contrast their effectiveness and scalability, we
propose a real time fuel consumption information feedback mechanism to study its impact on
changing driving behavior and patterns.  A pilot study is under way to quantify its
effectiveness and we report our preliminary findings here; (3) How does privileged traffic
information impact traffic flow and benefit subscribers of such information?  We provide a
simple network example to examine the value of information and the impact of it on
commuter travel time.  A more complete mathematical model is being developed to provide
insight on the value of real time traffic and incident information. Collectively, they seek to
address the following questions: (1) What ITS-related incentive mechanisms (and others) are
available to promote efficient driving? (2) How will users behave under situations of
information asymmetry? (3) What is the value of information to a user as such information is
disseminated more broadly?
