Personal Mobility

The paper describes the iMove® project including the use of ITS Corporation’s structure to
bring together the efforts of many existing regional agencies in the Vancouver area to create a
unified multi-modal traveller information service which bundles information to cater for the
needs of specific user groups. The design of the iMove® system is in conformance with the
Canadian ITS Architecture and NTCIP and ITE ITS data and interface standards. The
iMove® service allows road users to avoid incidents and municipal construction zones,
minimizing congestion to reduce accident potential thereby improving overall road safety.

This paper describes an on-road assessment of voice-activation interfaces for in-vehicle
navigation operations. Using an Instrumented vehicle, drivers were asked to perform destination entry
tasks using three voice interfaces, the traditional voice-activation interface, the intuitive voice interface
with text prompts at central display and an intuitive voice interface with text prompts on a cluster
display. Driver performance was analysed using task performance, visual behaviour and driving
performance measures to characterise distraction effects of the different interfaces. The results
suggested that distracting effects in using voice-activation interfaces for the complex destination entry
tasks were found to be acceptable.

This paper describes simulation studies on the effect of the inter-vehicle communications on the
improvement of traffic flow along an expressway, and shows the relationship between the
penetration rate of the communication unit and suppression of the shock wave. In the simulation,
20 vehicles are assumed to drive at the same speed of 15 [m/s] and the same headway of 2 [s] or
2.5 [s] along a single lane, and then the lead vehicle slows down with the acceleration of -1 [m/s2]
for 2 [s] and then speeds up with the acceleration of 1 [m/s2] for 2 [s]. If a vehicle is equipped with
a communication unit, it can control the speed without any delay with the data transmitted from a
preceding vehicle to prevent the shock wave to propagate upstream. The simulation results show
that the effective penetration rate of a communication unit is at least 20 % and 10 % for the
headways of 2 [s] and 2.5 [s] respectively.

The intelligent mobility assistance project is designed to establish a ubiquitous environment
where anyone can access information on traveling routes, transport means and destinations at
any time and any place and to create a “Universal Society” where anyone plays his/her own
role and supports each other.
Under the sponsorship of the Ministry of Land, Infrastructure and Transport, probing tests for
the project have been carried on throughout the country.
In fiscal 2007, Toyota City conducted a probing test to utilize cellular phones to provide
regional information, traffic information and barrier-free information under a public-private
partnership. The aim of these efforts is to create a community friendly to pedestrians in the
central part of our city. This paper introduces the content, evaluation, technical
specifications of the probing test, as well as describes the development in the future.

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.
