Personal Mobility

Nowadays there’s an increasing need to guarantee people’s mobility at acceptable cost and in
safe conditions, and to provide mobility related services according to the user’s profile. Safety
and comfort, co-operation between vehicle and infrastructure or service centre, configurable
human machine interfaces according to user’s profile, are key concepts which will
characterise the future vehicles. In this context, special care has to be dedicated to elderly
people’s needs as road users. OASIS Integrated Project comes to fill this by proposing an
elderly friendly transportation information system and route guidance, as well as technologies
for promoting personal mobility. In this paper emphasis is given to the personal mobility
promotion, by developing elderly drivers’ real time stress and discomfort assessment
algorithms and automatic seat and key vehicle configuration elements.

JustNu (translated “Right Now”) is SL’s (SL common short form for AB Storstockholms
Lokaltrafik, translated Greater Stockholm Public Transportation Authority) main focus
project to provide the Public Transportation operations four transport types (buses, local trains,
metro and commuter trains) in the Greater Stockholm area with real time traffic information
and data. The main purpose is to provide traffic information on SL transport services to be
available to all customers. This means to provide real-time reliable and easily accessible
traffic information and data, before and during the journey to the traveler, so the traveler can
plan and travel the entire journey with SL.

A survey conducted on behalf of the Metropolitan Transportation Commission’s (MTC)
2006 Transit Connectivity Plan found that travelers use all available sources of transit
information including in-person assistance, printed materials and Web sites to support
pre-trip and en route transit trip planning. According to the plan, customers also showed a
strong interest in real-time departure information, wanting the information to be logically
located and easily readable. Kiosks were cited as one of the ways that the real-time
information could be disseminated. In order to provide these sources of information to the
public, three key Bay Area transportation agencies – Bay Area Rapid Transit (BART),
San Francisco Municipal Transportation Authority (SF MTA or Muni) and MTC –
partnered on the Transportation Information Kiosk Project, which began as a one-year
pilot in the Embarcadero BART/Muni station in San Francisco.

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?

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
