Cross-cutting Issues

In this paper, improving DS/SS inter-vehicle communication using p-persistent
CSMA MAC protocol is studied. It is possible for p-persistent CSMA to adapt optimally to
current packet traffic situation by setting p to an appropriate value. Therefore, improvement of
IVC performance is expected if optimal p value can be set according to the traffic of vehicles.
In order to perform this, the scheme where the traffic monitor on the road side informs the
appropriate p value to each vehicle in the area using road-vehicle communication is proposed
and its performance is analyzed by simulations.

SRA (The Swedish Road Administration) has since 2002 used Bridge-WIM systems. The
result has so far indicated a widespread overloading. The information is also important for
planning of road maintenance. Weight monitoring has thus provided SRA with vital
information. SRA has decided on an action plan to address the problem with overloading. The
action plan will generate new ITS-solutions and continued weight monitoring in Sweden. One
example is on board weight control on Heavy Goods Vehicles (HGV). This could have a
greater impact if there are a European and international co-operation and harmonisation on
electronic vehicle identification and remote declaration of vehicle characteristics. Overloading
is a cross border problem. On the next ITS World Congress in Stockholm 2009 we intend to
show different aspects on the concept “a correctly loaded vehicle”.

The Connected Vehicle for Safety, Mobility and User Fee Project is an extensive demonstration project undertaken in parallel with other Connected Vehicle Programs.  MnDOT’s efforts include designing, building, and testing three new software applications that combine safety and mobility applications from the Connected Vehicle world with a mileage-based user fee (MBUF) application from the road user pricing world. The desire to mix Connected Vehicle and MBUF applications on a single commercial off-the-shelf (COTS) platform presents challenges to the architecture and design of the system as the functionality and needs of Connected Vehicle applications are different from the MBUF applications. This presentation will summarize the System Architecture/Design developed for this large field demonstration of MBUF.

This study attempts to develop a Geographic Information System (GIS) based system utilized in identifying ramp site that can potentially benefit from ramp signaling. To achieve this, this paper first identifies and evaluates existing ramp signaling guidelines, and then establishes a set of warrants with consideration for their appropriateness and the availability of the required data. A web GIS system is developed that integrates data required for ramp signaling justification from various databases that currently exist and operate independently. The established warrants are included in the system to ease the analysis. The interface and functions of the system are described in this paper, followed by a case study from a set of ramps along a segment of I-95 in Miami-Dade County in Florida.
