Comprehensive travel information is a critical factor in tackling traffic congestion in
the U.S. and other countries, where bottlenecked roads and extraordinary delays often
approach crisis conditions. The goal of this paper is to illustrate how a consortium
approach to the collection and processing of traffic impact data, which integrates and
coordinates existing, independent data systems and delivery platforms, can improve
both information and communications to private and commercial drivers as well as
public agencies and yield a range of benefits, including more efficient travel,
enhanced road safety, lower pollution and fuel conservation.

The City of Santa Clarita is situated in-between Interstate 5 and State Route 14 and is a fairly
small size City compared to the neighboring City of Los Angeles. A large percentage of traffic
in the City of Santa Clarita utilizes arterials as alternate routes to the Interstate 5 and State Route
14, given the road network configuration that has numerous parallel arterials to the freeways (1).
The City of Santa Clarita identified that the implementation of Advanced Traveler Information
System (ATIS) locally can provide the greatest value to residents and other travelers. ATIS
could also provide travelers with detailed information about traffic incidents, the weather,
construction, and special events by linking the resulting system with other ATIS in the future
through Caltrans, Los Angeles County, and other local agencies. The concept of ATIS for the
City is unique because of the scale of the system required to be implemented compared to larger
- 2 -
public agencies such as City of Los Angeles and County of Los Angeles. The implementation of
ATIS will improve travel predictability allowing drivers to make choices and reducing
congestion. The City of Santa Clarita received funding for an Intelligent Transportation Systems
(ITS) Phase 2 project as part of the Metropolitan Transportation Authority (MTA) call for
projects. This project calls for the installation of traveler information data collection, integration
and dissemination systems in the City. The project will install system detection at 16 locations,
Closed Circuit Television (CCTV) at 10 locations, 3 portable Changeable Message Signs
(PCMS), Fiber Optic Interconnect Gap Closure and a Traveler Information Web site to
disseminate information on the city streets and the adjacent freeways to the travelers in the city.

The Mobility Services for All Americans (MSAA) initiative is a United States Department of Transportation’s (USDOT) Intelligent Transportation Systems (ITS) research initiative that aims to enhance the efficiency and quality of human service transportation utilizing ITS. Travel Management Coordination Centers (TMCC) demonstration is a major outcome of the MSAA initiative. ITS forms the basis of the TMCC system by enabling two essential functional features: 1) enhanced real-time traveler information capability, and 2) improved or enhanced operational coordination through advanced ITS fleet management tools. In 2008, the USDOT selected Aiken (South Carolina), Camden County (New Jersey), and Paducah (Kentucky) to develop and demonstrate the technological and institutional feasibility of a deployed TMCC and to assess its impacts. In 2010, Aiken and Paducah TMCCs became operational and began a new era of coordinated community transportation services. The Paducah KY TMCC received the 2010 Community Transportation System of the Year Award by the Community Transportation Association of America (CTAA). The process and approach that led to the ultimate success of these two TMCC demonstration projects suggests that while each TMCC design was significantly influenced by local unique operational needs and characteristics, certain foundational ITS capabilities, such as Computer-Aided Scheduling and Dispatching (CASD), are required by all. This paper documents real-world results from the Aiken deployment and confirms that human service transportation in general is an “under-challenged” area where ITS can make a major impact.

Walking is the most fundamental means of human transportation. Unlike travel by car, human
movement, either on foot or with the aid of a wheelchair, includes vertical movement, using
stairs or elevators, for example. Although there have been amazing developments in car and
outdoor navigation systems, such as EZ-Naviwalk, navigation inside buildings or between tall
buildings is less advanced. We therefore propose a new 3-D positioning system that is driven
primarily by dead reckoning with the support of RFID technology, which can provide realtime
indoor or outdoor position seamlessly. This enables point-to-point ubiquitous navigation
for humans even inside buildings or between tall buildings. In addition, this pedestrian navigation
system can take user’s preferences into account by changing the costs of the road network
link costs in various ways. Altitude differences along the route may be important. For
example, routes having stairs must be avoided by wheelchair-bound users. In addition, timedependent
routing must be considered for indoor navigation. A positioning track accumulation
system is also implemented so that tracks can be stored and their information reflected in
order to incorporate new roads or attributes in the future.

It is understood that estimation of travel time on an urban express way is difficult because heaviness  of  congestion  differs  from  day  by  day  and  from  hour  by  hour.  Especially  the accuracy of the estimation gets worse with an external factor of traffic flow theory such as rainfall,  a  fallen  thing  from  a  heavy  truck  on  the  road  and  a  traffic  accident.  The  paper introduces  Bayesian  statistics  to  the  estimation  in  order  to  overcome  the  problem.  From Bayesian theorem a vague prior probability of occurrence of a certain travel time is revised by a  conditional  probability  which is  calculated  as  a joint  probability  of occurrence of  these factors under a certain travel time. The revision accomplishes more accurate estimated travel time from the posterior probability. The paper tries to establish the method in a case study on the MEX (the Metropolitan Expressway) in Tokyo, and an acceptable result is presented.
