Description

COMPREHENSIVE TRAFFIC CONTROL SYSTEM WITH INTEGRATED COMMUNICATIONS

TECHNOLOGY

FIELD OF INVENTION

(01) The present invention is a comprehensive traffic control system comprising integrated communications technology with a user interface for providing detailed, relevaflt, and real time data to motorists and pedestrians in which collaborative manner, the system is able to make road junctions safer by increasing the effective control of vehicular traffic flow and pedestrian crossing.

BACKGROUND

(02) Recently, the incremental innovations made in response to new technology have helped to improve the safety and efficiency of traffic control system. However, these systems have been limited in the amount of information they have been able to convey, relying on a basic system of coloured lights and arrows. Whilst this is effective for signalling, the lack of information can leave motorists and pedestrians confused and frustrated especially at complicated junctions with longstop periods. Such problems have been exacerbated in recent years with the introduction of traffic light systems with sensors that can detect approaching emergency vehicles and change their pattern accordingly. In such situations, motorists can find themselves sat at a red light for an extraordinary long time creating confusion, anxiety, and frustration. Consequently, motorists can begin to creep out which in effect can be a hugely dangerous manoeuvre that can cause fatal accidents considering the emergency vehicle hurtling towards the junction. It is because of such drawbacks that this invention has been designed to allow far greater information to be communicated to motorists and pedestnans in ensuring the safety and effective control of road junctions. Feasibility and technical specifications of the present invention are widely investigated particularly the work involved in designing the system so that it is able to be installed at UK or overseas road junctions. Also, to ensure that all of the required parts of the development are investigated and planned to ensure a complete project development as a unique, competitive, cost effective, and environmentally friendly product. Fundamentally, the overall traffic control system is created from individual units integrated together' with the intent of creating a one unit embodiment' However, these units maintain their individual characteristics in the process as this allows for each unit to be specifically designed as a separate module' in meeting legislative requirements. Accordingly, an overall controller' interface is designed to integrate/synchronize such units and their individual controller modules' to determine the overall function and control of the traffic system. As a result, in a collaborative manner, the traffic control system is able to make road junctions safer providing incalculable opportunity for motorists and pedestrians with roads ) less stressful and interactive to use in an enabling technological environment. That said, the skilled art of the present invention, the scope of its modification, and uniqueness of its embodiments as herein cited, are unlimited in pursuance of further exploratory development and architectural extemporization.

(022) In FIG.5 according to means 3, display of data is governed by the document "[1] -SI 2002:3113" as it details the size and style of legend acceptable to use. With reference to the document above, the resolution of the traffic control system's prescriptive method' of utilising such matrix style display as cited in the former is categorically defined. In use, with reference to the said matrix style display, each element of the matrix illuminates bright LEDs of which single sections are controlled from the microcontroller with effects of sunlight addressed to allow for the system to be readable at all times dunng the day of which selected light intensity is hitherto governed by legislation with its resolution also determined by the said legends, sizes, and display technology.

(023) In FIG.2 according to means 7, the said miniature interfaces are to display data to pedestrians, and possibly to motorists as well who may be caught up within close proximity. This is to ensure minimum confusion possible at road junctions. Moreover, it has been assumed that a person would be looking at such repeater displays 7 from a distance no further than approximately 1 Om while the main display interface 4 is also projected to display at approximately 50mm diameter.

(024) In FIG.3 according to means 8, the overhanging housing 3 is serviced from time to time thus, two systems are devised to allow this to happen as follows (a) a cable lowering system which utilises 2 pulley cables to raise/lower the housing from the said pole with the housing when lowered, leaves the entire mounting structure in situ with a connector to allow for the signal/power cables to be disconnected while being lowered with a locking mechanism designed to secure the housing until the housing is returned to the operational position of which configuration also includes a connector port located inside a panel which the service engineer can access which also allows for the engineer to plug a cable into the lowered housing in enabling the engineer to carry out the operation of the said servicing; and (b) an additional option of a standing lowering system which utilises a similar methodology as some static speed cameras which also utilises I vertical pole from which the system protrudes over the carriageway of which system when raised/lowered, allows for the whole system to rotate through 90 degrees before raising/lowering in ensuring that the servicing of the housing does not block part/all of the carriageway of which mechanism also allows for the housing to be lowered and accessed by means of a door' (not shown) used to secure the housing in the up-position.

In practical terms, both servicing methods are feasible. The system is as well stable even in adverse weather conditions with the housing also secured in the operational position.

(025) In FIG.5 according to means 3, a countdown timer as well as current time (not shown) are integrated by means of the said matrix style display 4 with an additional devise for the controller to tie in with the phasing of the existing system.

(026) In FIG.4 according to means 3, a moving emergency or special vehicle should not be delayed by normal traffic and/or traffic jams. The vehide should not need to wait for change in the traffic light or decongestion of traffic. Accordingly, traffic lights change prior to the emergency vehicle arrival to allow for the congestion to disappear. As such, any special vehicle on the crossroads is allowed to turn in any required direction using a light changing signal to allow for the safe passage of the vehicle in the required direction. Where two special vehicles move on a colliding route, priority vehicle is calculably selected as the system analyses the movement direction of the approaching special vehicle to ensure that it does not trigger the incorrect lights.

Aq analysis of the time of two special vehicles arrival if two crossroads are in the vicinity is set to differentiate which vehicle would arrive first. The system is secure and cannot be abused by the third parties involved in the process however, granting the inevitability of possible human error, a systematic guide for control of use is catered for, and upheld throughout the entire process of the system's operation.

(027) The emergency or special vehicle system is designed in several ways which differ in the quality of solution, technical advancement, price of development and implementation requirements. During operation, determination of the direction, location, speed, and overall destination of such vehicles is monitored from GPS data being passed back to a control system which then determines the best route for the particular vehicle to use in order to safely get to its overall destination. Hence, the operation of the traffic system at each junction is controlled in such a manner that there is minimum congestion in the said required direction at each road junction for this purpose. This process is established by way of a permanent connection to a central server/controller of which interface is to primarily report of the position and location of the approaching vehicle in ensuring the servers optimal routing calculation for such particular vehicle.

(028) In FIG.4 according to means 3, an interface is developed for the main controller for each set of traffic control system which allows for a remote controlled change of the lights which is rapidly managed by the said central server.* In principle, each emergency or special vehicle can be tracked or monitored of which routing/control algorithms are rapidly updated to remove bottlenecks in the journey. The wrong traffic junctions are not to be triggered by the said emergency or special vehicle in the vicinity as the central server will know which junctions need to be controlled and when.. All new traffic junctions are practically included in the central server/controller as soon as they have been installed as otherwise some junctions will not be controlled by this system due that new traffic junctions also affect the algorithms based around traffic systems that are local to the vicinity.

(029) The central server/controller is analytically programmed with mapping and routing software to plan for each urban, suburban or area routing, Principally, all traffic lights 5 in conjunction with data display panels/boards have a connection to this central server/controller for the sole purpose of fulfilling the entirety of the system's effective operation. In both FIGS.4, 5, the traffic lights 5 in conjunction with the data display panels/boards are controlled locally at each junction to ensure that each junction is still maintained from the next junction. Priontising on the safety of both motorists and pedestrians particularly on the approach of an emergency or special vehicle, a signal is transmitted from the said particular approaching vehicle to a local controller which in synchronization, automatically activates the traffic system's signal interface to change the lights several seconds before the arrival of such vehicles in ensuring a precautious, smooth, and safe passage. The central server/controller is not required here and so minimises the overall data bandwidth required.

This system can be implemented into many different services to allow for the timely movement of the said vehicles when required. It has been pragmatically projected that to achieve such fulfilment particularly of the traffic control system, a GPS system must be incorporated' into each emergency or special vehide respectively so as to enable the controller to determine their monitoring, heading, location and speed with the aim of ensuring safety as well as effective vehicular traffic flow at road junctions.

On an approach to a junction, data is transmitted from the particular approaching vehicle by way of encryption to allow for the traffic light controllers in the available range of the transmitter to receive the signal. To ensure that this system is not miss-used, the system would incorporate the status of the blue flashing lights when they are in the operation process, thus under normal (non-emergency) situations, the system does not trigger the lights. Each traffic light controller is programmed to respond appropriately to these signals. In the situation where the particular vehicle is not reporting of its location on the approach, the interface devise will not change the lights. This solves the problems encountered with the broad RF solution, and does not require any new infrastructure to be installed however; it may require modification to the existing junction control systems.

(030) In the likely event where the system implements a new traffic control algorithm to help prevent congestion (using both FIGS.4 and 5 as an example), the system automatically becomes part of an overall central control database which controls and manages each traffic control system installed. Traffic control systems for selected areas are divided into the following modules i.e., (a) Strategic module, (b) Tactical module, (C) Local module, and (d) Communications Interface. The strategic module creates real-time model of traffic interactivity including predictions of the traffic flow for the forthcoming time based on the data obtained from key traffic measuring points in the city or particular area. These predictions are rapidly verified and updated with the current data. The system also analyzes traffic flow data for other road users e.g., pedestrians. In this model, it is also possible to take into account the pedestrian movement across the road. With effect, the strategic module prioritises on public transport and effective traffic management. The system develops the whole strategy of the traffic management for the area of the traffic control system and in most cases, with meteorological data also included in the analysis. Several algorithms as well as fuzzy-logic based systems are innovatively used in the process.

(031) In the event where it is not possible to direct the traffic flow smoothly on selected routes as exemplified in FIG.4, the congestion is shifted to alternative routes. Data on such alternative routes is dynamically displayed 4. Thus, the priority of this traffic model is based on a selected area in determining the strategy for the routing linked to the sub-regions as well as managing their linked pedestrian movements. Subsequently, the time of the green light 5 remains set with network of appliances and controllers also co-ordinated by the tactical module so that no irregularities in the sub-area connection occur. Additionally, the controller for the strategic module determines the said alternative routes which in the process also allows for a decongestion ing of all other main routes.

(032) The strategic module controller estimates the congestion of traffic in a given urban or suburban area for the next 5, 10 and 15 minutes with rapid updates created every 5 minuteS. The tactical module controllers then manage the area along with neighbouring junctions. The tactical controller collects data from car and pedestrian traffic analysers along with routing targets set by the strategic module. Based on the routing strategy and targets received from the strategic module controller, the tactical module creates the real signal' which then determines the green light time period' for all controlled directions.

Additionally, the strategic module controller generates the signal which allows for the coordination of the tactical module's operations in the borders of the said areas. This signal determines when, on what terms, and for how long the green light should be turned on to allow for uninterrupted and smooth traffic movement between subareas compositmg the entire urban road network. The timing and routings calculated by the strategic and tactical controllers are designed to comply with existing legislation as herein referenced.

(033) Furthermore, the tactical module controller collects data from traffic controllers and analysers on crossroads and traffic routes in determining routing algorithm. Based on the current data and vehicular/pedestrian traffic movement predictions determined by the strategic module in a selected area, the tactical controller further determines the tactical cycle values for the local devices (traffic lights and information boards on the junctions). With particular reference to emergency and special vehicles as exemplified in FIG.4, data is sent from the tactical controllers to the local traffic routing systems to allow for the smoothest and safest passage possible.

Routing values are created based on the routing algorithm operating along with fuzzy-logic with data transmitted to the local device network. The local module is comprised mostly of the traffic control system installed at each junction where measuring devices and traffic analysers before, and after junctions, are installed. In places with extensive pedestrian traffic, analysers capable of predicting pedestrian congestion are also installed as well as safety devices which allow for the recording of crossings on yellow and red lights 5.

(034) As exemplified in both FIGS.4, 5, traffic system controllers on junctions which create the local module, carry out the real-time traffic light routing based on the data received from traffic analysers and tactical module controllers. Communications between the different elements of the systems and modules are camed out along with the implementation of various means and various media. As such, the hierarchical structure as cited above limits the amount of data required to be sent which is received from the strategic and tactical module controllers. The strategic controller does not require full data from the junctions in order to predict the traffic movement in the whole area as its predictions are based primarily on the said key strategic measuring points. And, since the tactical module only manages specific urban or suburban areas, the amount of transferred data by the tactical module is measurable.

(035) As the system display emergency Information as exemplified in FIG.4, an additional feature such as an automated voice may be employed to announce that an emergency or special vehicle is approaching, or to announce that the crossing is about to change. For pedestrian crossing, the referenced legislation ("[5] -Performance Specification for Audible Equipment for use at Pedestrian Crossings") dictates the specific sounds to be included in this process.

Where an automated voice is integrated into the system, devices are available which can interface directly to the controller of the unit providing multiple messages of between 5 and 30 seconds long. This may include an amplifier and directional speaker in ensuring maximum audio output in the correct direction. The existing legislation ("(5] -Performance Specification for Audible Equipment for use at Pedestrian Crossings") also dictates that the intensity of the sound is to be settable between 47 dB(A) and 83 dB(A). These settings also include voice automation devise in the traffic control system.

(036)The operating conditions for the traffic control system are practically defined by legislation ("(6] -BS 7987:2001 Road Traffic Signal Systems") and ("[9] -EN 60068-2-2 Environmental testing -Part 2-2: Tests -Test B: Dry hear) for the operational dry heat that the system is tested to.

The document ("(5] -Performance Specification for Audible Equipment for use at Pedestrian Crossings") defines the MTBF for the audible systems as a minimum of 12000 Hours while Section 6.3 of the document ("(6] -BS 7987:2001 Road Traffic Signal Systems") also defines all of the environmental requirements governing the design architecture of the traffic control system.
