Service Enabling Paradigm For 3rd Party Value-Add Telematics Via The German Road Charging System
When the German satellite-based road charging scheme for commercial traffic took off in
2004, the dual public-private nature was deeply engrained right from the start. Institutionally,
this dual character is most clearly visible in the operation venture, Toll Collect which is a pri-vate company but answers a German government authority. In the business architecture, the
public-private character consists in a principal design that allows the shared use of basic sys-tem functionalities for both, the actual road charging process and service offerings of private
parties. It should be reiterated that the addressees of these offerings obviously are the stake-holders in commercial traffic only.

Serial Wireless LANs Along DOT ROW
This paper presents the use of Commercial off-the-shelf (COTS) wireless Internet
technology to meet the security, mobility and safety needs of departments of
transportation (DOTs). COTS wireless is an economical, scalable alternative to
traditional fiber optics and telephony communications solutions. A virtual Ethernet
network is created along a highway right-of-way (ROW) by installing wireless point-to-
point links in a serial fashion that can extend upwards of 30 miles per section from a base
node. This local area network (LAN) becomes a seamless extension of the DOT’s
communications for field devices such as cameras, RWIS, traffic sensors, and field
personnel. This paper discusses cost comparisons to traditional communications, specific
types of wireless technologies, their capabilities, architectures, and security issues based
upon Virginia Tech’s real-world deployments and test-bed installations. Digital video
applications along wireless networks are specifically addressed. The paper concludes
with a discussion of the near-term future of wireless technologies.

Self-Organizing Traffic Control For Congestion Avoidance And Traffic Flow Improvement
Social insects perform complex, self-organizing tasks in the collective by using pheromonebased
indirect communication. Following the example of nature, this concept could also be a
paradigm for controlling traffic, for recognizing and avoiding traffic congestions, where
vehicles act like individual insects by depositing digital pheromones in order to indirectly
benefit from their trail.
Vehicles equipped with emerging positioning and communication technology virtually
annotate their local environment and form a collective with decentralized, self-organizing
capabilities.
In this paper we present an approach for a technical implementation of a pheromone-based
traffic system and try to prove that this concept from nature is also valid for controlling the
traffic flow by using a complex micro simulator capable of simulating real city networks.

Security Measures for Broadband Docsis Cable Modem Communications of Traffic Data
The advent of cable modems conforming to the Data Over Cable System Interface
Specification (DOCSIS) has created an ever-increasing communications infrastructure,
not only for the typical homeowner, but also for the homeowner supporting a Small
Office Home Office (SOHO) and for other small businesses.
The use of DOCSIS cable modems can also be extended to support communications of
traffic data to provide enhancements to existing communications methods. Tests are
currently being conducted at the City of Fort Worth Traffic Management Center (TMC)
using commercial grade and extended temperature grade DOCSIS cable modems to
characterize communications performance parameters and to identify system
constraints.
Whether for the homeowner, the business community, or a TMC, security measures are
vital to ensuring data integrity. This paper will provide an overview of the Community
Antenna Television (CATV) system and the cable network infrastructure. In addition, a
description of the DOCSIS cable modems and how they are being used in a novel
approach to transmit traffic data will be presented. Finally, an overview will be provided
describing the tests being conducted by the City of Fort Worth using the CATV and
DOCSIS cable modems and the security measures that should be considered when
using DOCSIS cable modems within the CATV cable network to provide transmission of
traffic data.

Securing Wireless Access For Vehicular Environments
An Intelligent Transportation System (ITS) technical architecture has been developed based
on IEEE 1609 Wireless Access for Vehicular Environments (WAVE) standards for secure
vehicle-to-vehicle and vehicle-to-infrastructure wireless communication. This study
examines the wireless security technology, IEEE 1609.2, WAVE Security Services for
Applications and Management Messages, as an Identity and Access Management solution to
the challenges of the ITS model program. An examination of the working model
demonstrates the use of a 1609.2 Public Key Infrastructure (PKI) to manage ITS actors,
messaging and applications using DSRC/WAVE communication services.
