BACKGROUND OF THE INVENTION
This invention is generally directed to telephone and computer accessible
information systems for providing subscribers with continuously updated
information regarding a variety of subjects or topics of interest. In a
preferred embodiment, the invention is directed to a traffic information
system for advising travelers of conditions along vehicular routings in
metropolitan areas and more specifically to a traffic information system
which may optionally transmit information directly to subscribers by way
of telephone, mobile telephone, computers and personalized pagers. The
system is designed to enable subscribers to immediately obtain specific
and updated information utilizing analog or digital communication
equipment or combinations of equipment. The system is further designed to
continuously monitor various conditions such as the conditions along
various vehicular routings and automatically initiates call-back
information to a subscriber's telephone, computer or digital pager in the
event any significant changes in conditions have developed. In alternative
embodiments, information such as airline, train and bus schedule
information, stock market activities, news reports, specific directions
and related travel information may be made available to a subscriber.
Further, once a subscriber has accessed the system, update or response
information may be selectively transmitted to a subscriber's personal
computer, telephone and/or alpha numeric pager.
2. History of the Related Art
One of the major and evergoing problems in metropolitan areas is the
overcrowding of streets and highways due to increased commuter traffic.
Anyone whose has ever lived, worked or traveled through a major urban area
during the primary commuting or rush hours has experienced the frustration
and exhaustion of bumper-to-bumper stop and go traffic conditions. A
single mishap or accident along a major arterial road or highway can
create hours of delays in commuter travel time and may effect thousands of
motorists.
The problems associated with commuting in major city areas not only causes
immense emotional and physical frustration for those immediately affected
by the long delays but also takes its toll in increasing the potential
risk of additional accidents and/or injuries. Further, such delays
increase automobile emissions which adversely effect the quality of air
and the environment. Some psychologists have said that the daily stress of
commuting can lead to reduced work productivity, strained family
relationships, and heart disease. Such delays also account for losses in
business revenues due to reduced employee work time, missed appointments
and the like.
In an effort to alleviate the commuter traffic problem, cities and local
governments have begun spending large revenues to build or expand mass
transit systems including expanded bus and commuter rail services.
Unfortunately, most transit systems cannot and have not been totally
effective in alleviating the traffic problem associated with traveling
along urban area highways during peak use hours. In more recent efforts to
monitor highway traffic conditions, city, state and local governments have
begun utilizing video surveillance systems, electronic traffic detection
devices as well as increased traffic reporters and spotters both along
highways and in the air. Using continuously updated traffic information,
local authorities are attempting to respond more quickly to exigent
conditions which can cause major traffic back-ups such as accidents,
breakdowns or faulty traffic control including stoplights or ramp control
lights along major arterials.
Government monitoring and control of traffic conditions are helpful but not
preventive of large traffic tie-ups. During peak travel hours, if traffic
flow is interrupted for only a period of minutes, the resultant back-ups
can create gridlock and cause hours of commuter delays in travel time.
Realizing that commuters and not just government agencies are in need of
local traffic information, commercial businesses have been created to
provide such information to local television and radio broadcast systems.
Such commercial businesses not only monitor information received from
local governments, police, fire and rescue sources but also receive direct
reports from individuals who travel the various commuter routings during
peak or rush hours. The broadcasters barter the information which has been
assembled and make it available to their listeners.
Because traffic information is one of the foremost concerns of many radio
and television audiences, some stations further supplement information
received from both commercial and government sources with their own
traffic spotters both on the ground and in the air. Air traffic services
enable broadcasters to receive and transmit reports of existing traffic
conditions by low flying aircraft who can reach the scene of a traffic
problem very quickly and without being delayed by local vehicular traffic.
Unfortunately, an aircraft can only be in one area at a given time and in
most metropolitan areas, it may take up to an hour or more to fly a
complete circuit around the city. Also, aircraft reports are only possible
when weather conditions permit aircraft to be in service.
The primary shortcoming of the presently utilized metropolitan traffic
information systems is that they are not responsive to the traveler. The
systems are necessarily limited to making generalized information
available. Such information may be specific to certain groups of commuters
using a common route or arterial in a given hour but are not effective in
providing commuters on differing routes continuously updated information
regarding the travel conditions to be expected along their routes or
alternative routings. All too often, commuters await information by way of
a chosen broadcast system relevant to their route, only to find that the
reports are too late and they are already caught in time-delaying
back-ups, or because conditions have changed moments after a traffic
spotter or aircraft reporter has passed a given area, they are led to
believe that their route is open and traffic moving smoothly only to find
that they are now just one vehicle in an arterial parking lot.
Information systems have been proposed that will make traffic information
directly available to specific vehicles. Some of these systems utilize
central processing stations which transmit information to vehicles at
given areas or locations. In U.S. Pat. No. 4,301,506 to Turco, a routing
computer system is disclosed wherein a vehicle operator may utilize an
onboard computer system to access data concerning routings between two
points. The computer provides a visual read-out of directions to travel
from one point to another. The system also includes circuitry which will
provide or indicate alternative routings in the event a preferred route
becomes blocked or tied-up. Unfortunately, such a system requires the use
of a vehicle mounted computer having keyboard and video display equipment
which are not only not practical but are not cost effective for individual
commuters. Further, such systems are only designed to provide alternative
route information in the event a back-up is encountered. There is no
provision for updating or monitoring existing traffic conditions in order
to provide information to avoid a particular route. In essence, the system
is an electronic mapping data base which provides route designations
between points but not present traffic conditions.
In U.S. Pat. No. 4,350,970 to Tomkewitsch, another traffic routing and
information system is disclosed. In this system, stationary routing status
transmission poles are used to monitor traffic flow and to transmit
information concerning traffic conditions to passing vehicles. The system
requires that passing vehicles to be equipped with equipment capable of
transmitting travel time information between the fixed pole locations in a
given vicinity. Such information is then utilized to evaluate traffic
flow. Information from the fixed poles is transmitted to a central
computer which then assembles the information and commands the fixed poles
to transmit pertinent information regarding conditions ahead to vehicles
approaching such fixed transmission poles. Again, such a system is not
practical or cost effective. The expenses of providing fixed transmission
poles along major arterials would be prohibitive. In addition, commuters
will not have access to information being transmitted until they approach
within transmitting range of fixed locations. Thus, a commuter will not be
advised in advance of a given location of the traffic conditions further
along the commuter routing.
As a result of the ever increasing traffic slow-downs and tie-ups which
effect business travelers and commuters, many individuals and businesses
have begun or increased the use of mobile telephone services to allow
their business people to conduct business when caught in time-consuming
delays along commuter routes. Although mobile phones and phone services
have not provided the commuter with ways to avoid traffic delays, such
services do permit savings in business time and revenues and also make it
possible for necessary information or decision making to transpire
regardless of travel delays to and from a place of business.
Some additional examples of vehicle guide and control systems which are
proposed for automatically routing vehicles are disclosed in U.S. Pat.
Nos. 3,845,289 to French and 4,009,375 to White et al.
SUMMARY OF THE INVENTION
This invention is directed to analog and digital information communication
systems for providing subscribers with continuously updated information
regarding a variety of subjects or topics of interest by way of telephone,
personal computer and/or personal paging equipment. In a preferred
embodiment, the invention is directed to a traffic information system
which is initially accessible to subscribers by Touch-Tone or dual tone
multiple frequency (DTMF) capable telephones or digitally, via modem. Each
geographic or metropolitan area which is served by the system will be
represented on a specially designed map which will illustrate major
thoroughfares and a unique color coded grid system to represent roads that
are not major thoroughfares. Using location coordinates and the codes used
to designate major roads, a subscriber will select a desired route. These
coordinates and codes will be represented to the system by way of a DTMF
capable phone or digitally by way of a computer/modem link. Information
from the system may be selectively transmitted by existing telephone and
mobile telephone networks for receipt by subscriber's telephones or
personal computers or by way of FM subcarrier modulation or existing
commercial paging signal transmission networks for receipt by a
subscriber's personal alpha numeric pager.
This system includes a central operations or control facility wherein
information is received, interpreted and disseminated to subscribers of
the service offered by the system. In supplying information in accordance
with the preferred embodiment, local traffic information will be received
from a variety of sources including existing government and commercial
traffic watch services, police, fire and rescue reports and advisories,
local radio and television broadcasts including on the spot or eye witness
reports, fixed wing aircraft and helicopter airwatch services and the
like.
All information being received at the operations control facility will be
interpreted by coordinators to determine if such information alters the
status along any of the predetermined routing areas. If any change has
occurred which will effect traffic flow from a normally anticipated flow
for a given area and, if the coordinator determines that a file update is
necessary, the information will be immediately placed within the system to
be accessed by or transmitted to subscribers.
The system includes a plurality of command nodes or communication channels
which interface directly with telephone and/or mobile phone services
and/or computers. Each node or channel will include a processing computer
and a multi-line voice communication system which are interconnected to
the system's central data file or fixed computer source which will retain
information regarding subscriber information to thereby control either the
acceptance or the transmission of incoming or outgoing information.
At the operations control center, the traffic information is filed and
stored in multi-line voice communication systems which not only record
messages relevant to selected routings but will dissiminate such
information through the multi-line voice communication systems associated
with each of the nodes or channels of the system. In the event of a change
in a given routing, operators at the operational terminal will voice
transmit such activity to the multi-line voice communication system which
will in turn feed such information to the fixed or central data computer
file source. From there, information is made available to the voice
communication systems associated with each of the incoming channels or
nodes. Upon the receipt of an incoming subscriber phone call, the voice
communication system (VCS) will provide current information by way of
audio transmission or digital transmission of traffic conditions at a
predesignated area to subscribers whose identity has been properly assured
by the computer network. Depending upon the service level desired by a
given subscriber, the VCS of the system will automatic redial and transmit
routing information to subscribers regarding changes in status along
selected routings as determined by the central data computer file source.
Subscribers to the system will have the option to request receipt of
initial reports or update reports in either analog (telephone/voice) form
or in digital (modem or pager) form.
The fixed, dedicated central data file computer or source will regulate
which information is to be made available to a given subscriber. In a
first level of service, subscribers may access information regarding one
or more given routes which are identified by predesignated numbers which
are coded into the computer through the subscriber's DTMF capable
telephone or digitally by computer. Once the system has insured that the
subscriber has identified themselves through an appropriate account, the
system allows entry of a preselected number of route groupings. A voice or
digital transmission is then allowed to be relayed from the VCS of the
node or channel thereby alerting the subscriber to the conditions along
the designated routes.
In a second level of service, the traffic information and status along the
designated routings which have been requested by the subscriber are
continuously monitored over a predetermined period of time with updates
being automatically transmitted to the subscriber to alert the subscriber
of changes in conditions along preselected routings. Transmission of
updated information may be by way of telephone (voice) communication or
digitally to a personal computer or pager. Transmissions to telephone and
personal computers will be by way of existing telephone and mobile
telephone systems while transmissions to pagers may be accomplished either
over existing commercial paging systems or by way of FM subcarrier
transmissions. An additional level of service would allow alternative
routings to be selected with traffic conditions being reported for such
alternative routings.
It is a primary object of the present invention to provide information for
travelers in metropolitan areas which permits them to directly access and
receive information regarding specific route designations which are
identified by coded numbers which may be entered into the system by DTMF
capable telephones or by digital means via modem and computer.
It is another object of the present invention to provide a traffic
information service to commuters in metropolitan areas which permits
commuters to obtain information regarding various travel routings directly
by telephone, mobile car phone, computer or alpha numeric pagers so that
the commuter will known the status of a given route and at the exact time
which the commuter desires to travel such route.
It is a further object of the present invention to provide traffic
information regarding specific routings directly to a subscribed wherein
the subscriber will not only have immediate access to existing traffic
conditions but wherein the service will automatically watch the conditions
along the preselected routings and reestablish contact with the subscriber
and inform the subscriber of any changes along such traffic routings so
that the subscriber can take appropriate steps to avoid areas of
congestion. Such a service enables the subscriber to automatically have
access to the most up-to-the-minute information by the operations control
computer system.
It is another object of the present invention to make traffic information
directly accessible to subscribers in their own automobiles by way of
mobile car telephones so that the subscriber may obtain updated
information regarding traffic conditions without having to purchase
additional radio, computer or other monitoring equipment.
It is another object of the present invention to provide an information
system which can transmit reports and information to a subscriber's
digital pager in either voice, LCD display or print modes.
It is also an object of the present invention to provide a relatively low
cost service for travelers in urban areas wherein commuters, for a fixed
fee, can obtain access to the most current up-to-the-minute information
regarding traffic conditions along a given or preselected route over which
the subscriber wishes to travel and which system has the capability of
allowing the subscriber to select alternative routings and receive
alternative information concerning such routings so that a decision can be
made to either alter a normally traveled route in favor of a secondary
route or delay departure time until the routing is clear.
It is another object of the present invention to provide a traffic
information service which is accessible by subscribers wherein information
is made readily available over telephone lines, mobile telephone systems,
computer systems, pagers or other communications systems directly to the
subscriber with the service being capable of updating information,
redialing or contacting the subscriber and providing the subscriber with
changes in information regarding preselected routes by utilizing existing
phone, mobile phone, computer and pager communications systems.
Another object of the present invention is to permit subscribers to access
continuously updated information by way of DTMF capable telephones,
including mobile telephones, regarding numerous subject matters including
travel industry schedules and related activities, travel routing
information, news and stock reports and other areas which may be of
interest and wherein reports may be received by telephone, personal
computer or digital pager.
