Abstract: Road traffic congestion becomes a major issuesfor highly crowded metropolitan cities like, Chennai .Ambulance service is one of the major services which gets affected bytraffic jams. To smoothen theambulance movement this paper have come up with the solution of “Intelligent automatic trafficcontrol for ambulance”. The proposed system creates aandroid app that connects both theambulance and the traffic signal station using cloud network. This system makes uses Beacon technologyto implement the Intelligent traffic signal control .
The basic ideabehind the proposed system is, if the Ambulance halts on the way due to atraffic signal, BEACON installed at the traffic signal tracks the BEACON taggedambulance and sends the data to the cloud. After the acknowledgment for the user through the mobile app, theparticular signal is made Green for some time and after the ambulance passesby, it regains its original flow of sequence of signaling If, this scheme is fully automated, it findsthe ambulance spot, controls the traffic lights. This system control thetraffic lights and save the time in emergency periods. Thus it acts as a life saver project.Keywords:BEACON, cloud Database, mobileapp, Microcontroller 8051,LCD Display, GPS Tracking System, Intelligentambulance. I.
INTRODUCTION: The main concept behind the paper is to provide a smooth flowfor the ambulance to reach the hospitals in time and thereby minimizing thedelay caused by traffic congestion. The Microcontroller based Beacon system is used to alter the traffic lightsupon its arrival at traffic light junction which would save a lives at critical time.Radio Frequency Identification is a tiny electronic gadgets that comprise of a small chip and an antenna. The smallchip is embedded with information’s about patience’s status and theambulance current lane .The BEACON reader located at the traffic signal reads these information from the BEACONlocator installed at the ambulance . To avoid unnecessary trafficsignal changes, we cross refer the ambulance current location and patience’scondition using mobile app registered by the ambulance driver..
In case ofnetwork failure, the BEACON takesthe whole control.This paper seems to be in a great need to make free flow ofambulance without stucking into the traffic. In the current situation itself, transportationof a patient to hospital in emergencyconditions seems quite simple but in actual it is very difficult during peak hours.
Moreover, the situation is gets worse when emergency vehicles have to waitfor other vehicles to give way at intersections with traffic signals . As thesurvey aye 95% of the heart attack cases can be treated , if the ambulance canreach the hospital at current time without stucking into the traffic. In future it may get evenworse . In this cause Recovery action need to betaken immediately. So, for our over populated environment ,there is a real needfor this paper for the society to make easier day to day transportations. Thispaper will help to reduce blockage of emergency vehicles in traffic and helpsto provide immediate recovery.· Mainaim of installed the paper is to providecommunication between ambulance and various devices at traffic signals and so that the possibility for trafficcongestion is reduced.· In this paper we contribute an overall system tomeet the above need.
It can be achieved by making useof two major technologies namely,ü Beacon ü mobile app with cloud access and GPS provided BEACON is to track the arrival of ambulance at traffic up to some distance. Mobile app to authenticate emergency and non-emergency conditions of ambulance. GPS to track the nearest traffic signal post to the ambulance and to send the app data to that particular signal post.
The data from BEACON and app can be given to the microcontroller to process the results and makes the signal change according to the result.· Both BEACONand mobile app integrate to serve the system without failure at any manner byalternatively working when other fails in its action.Thispaper helps in saving victims from the peak hour traffic. When it is beingimplemented it can act as a live saving project.
II RELATEDWORK:Thefour road intersection is a bottle neck for each urban traffic control. Severalsmarter methods need to be implemented for effective traffic management. Thealready existing system for Intelligent Traffic Control System(ITCS) proposedin 2 for emergency vehiclesimplements signal change by using IR sensors or BEACON technology.They don’thave an alternative method to controlthe flow, if anyone of the technology fails. They don’t survey whether the ambulanceis in emergency state or not. Because ambulance may also used in non-emergencysituations to provide facility to humans due to their health condition. In suchcases ,time limits are not considered. so it is not needed to make change in signals of traffic control system innon-emergency cases.
so in this paper special implementation for non emergencecondition as been included.The proposed work on 1 provides the basic connectivebetween cloud data ,traffic post and the ambulances. Microcontroller based intelligent ambulance system which can alter thetraffic lights upon its arrival at traffic light junction was proposed on 2.
The work in 9 proposeda traffic control system based on thewireless sensor network and an alerting system for red light crossing scenarioto alert the drivers on other sides to save their lives. This technique isbased on the queue length of the vehicles standing by the sides of trafficpost. The analysis in 5 gives a Traffic control throughsensor based system implementation and its outcomes. The BEACON workingand principles were obtained from various site references work6,7.Table: ExistingSystem comparison III PROPOSED SYSTEM:Inour proposed system, we are trying to implement an intelligent traffic controlsystem for ambulance ,that comprise of the following phases:(a)an android app:Appprovides four major options :ü Register –to register the ambulance to thecloudü Blocked – If BEACON reader fails, then after certain period of timedriver sends a “BLOCKED”command to the server .
At this case, based on server information the trafficsignal is cleared without verification.ü Emergency ü Non emergency –The android app is used tospecify current status of the ambulance whether is in emergency or non–emergency condition. The mobile app is also provided with GPS to track the nearest traffic signal post to the ambulance and to send the app data to that particular signal post. (b)BEACONtechnology :TheBEACON uses a BEACON tag for each ambulance , antennas along the road and BEACONreader at the signal post to track the position of ambulance.
(c)cloud storage :Thecloud system is used to store both app data and BEACON data and provides accessto the cloud whenever needed.(d)Micro-controllerunit:It actsas the centralized system to make traffic control .The data from BEACON and app can be given tothe microcontroller to process the results and makes the signal changeaccording to the result.Thesystem involves four scenarios as following:Scenario 1:If an ambulance atemergency is stopped by the traffic, then BEACON gives the ambulance data andusing app with cloud access which give value “emergency” by the user toauthenticate the change of signals in that lane to green and all other to red.Figure 1: Basic flow change ofsignalScenario2:If anambulance which is not at emergency situation is stopped by traffic, then BEACONgives the ambulance data and user gives value “not emergency” using the app tocloud, by which the signal will not unnecessarily changes the flow.Figure 2: Basic flow change ofsignal during Non-emergence Scenario 3: If an ambulance at emergency isstopped by the traffic ,but the BEACON fails to work correctly ,then using theapp the value “blocked” is given to the cloud after the user receives timed outnotification by the app , which will make the system to work without failure bychanging the signals.Figure 3: Basic flow change ofsignal during BEACON Failure Scenario 4:If an ambulance at emergency isstopped by the traffic ,but the network fails. So that we can’t access throughmobile app , at that condition BEACON makes the full role play by sending continuousdata to system over a long period of time, which makes the system to rummassively by signal changing criteria.
Figure4: Basic flow change of signal duringnetwork failure Thus by this alternate methods toimplement the system without failure can be done. IV IMPLEMENTATION OF WORKING SYSTEM : A. BEACON Technology:(BEACON)is a tiny gadget which uses radio waves to read and capture information of thetracking object. It has three main components namely(1)tag, (2)antenna and (3)reader.In our system, the tracking vehicle that is, ambulance is provided with the BEACONtag which comprise of 3 fields to store the data.(a)EPC-Electronic Product Codefor vehicle ID number ,(b)type of vehicle,(c)road lane number. The antenna isused to collect data from the tag and transmit it to the reader. The reader isplaced at some distance from the traffic signal, which may be mounted on roador platform that reads the from the tag by propagating RF signals to and fromthe object tag.
After reading data from tag, reader sends it to traffic lightsystem.Figure 5: Basic flow showingconnection of BEACON in the system.B. BEACON circuitin traffic signal:BEACON is a tiny electronic gadgetsthat comprise of a small chip and an antenna. This antenna sense the taggedambulance and alters the reader BEACON to get the vehicle unique identificationnumber. The received ID is passed to the database. After the authenticationfrom the server, the traffic signal is cleared for ambulance. In case of network failure, generated BEACON isprogrammed to clear the signal.
In case of BEACON failure, based on the mobileapp command ,signals are activated. 1. Retrieve status and deviceID signals from the device using BEACONreader2.
Store the device ID in microcontroller.3.Get the device status from thecloud server.4.microcontrollor program iswritten to satisfy all four conditions discussed above.5.
Based on the requirement trafficsignal is changed to green C. Integrating BEACONReader with Microcontroller: TheBEACON reader which contains the vehicle details of the approaching ambulanceneed to be connected with the microcontroller. The BEACON reader contains 9pins configured.
The 7th pin which contains the ambulance details is connectedwith the microcontroller. Here 8051 microcontroller with 40pins is used. The7th pin of BEACON reader is connected with p3.5(15th pin) of themicrocontroller.
To display the details in LCD the output pins ofmicrocontroller i.e., from p0.0 to p0.7 is connected to D0 to D7 pins of LCDdisplay.Figure6: Circuit showing architecture diagram attraffic light post D. Android MobileApp :Today we are living in an society where ourthinking is not possible without Smartphone’s.
So in this paper, Android app isdeveloped to provide additionalinformation about the patience’s status(EMERGENCY button present in his mobileapp) and current location using GPS system to the server database. The server in turn sends location and statusinformation to the traffic signal controller. The traffic signal is changed,after cross verification from the BEACON reader. If BEACON reader fails, thenafter certain period of time driver sends a “BLOCKED” command to theserver . At this case, based on server information the traffic signal iscleared without verification. Current location is sensed using GPS installed inthe mobile.
GPS or Global Positioning System is a network of orbiting satellitesthat send precise details of their position in space back to earth. The currentlocation information is send to the traffic signal controller through cloud. Hence,the app as basically four buttons Figure7: Basic Application developmentE.

CONCLUSION : Human life is precious and must follow safety measures veryconscious in all aspects this of course includes ambulances services too. Inthis, by using intelligent ambulance system we can achieve the uninterruptedservice of the traffic control system by implementing the alternate methods forsignal change to allow flow control. The accuracy of the BEACON is more than Camera’sso our proposed paper also improves the performance of traffic light Violation DetectionSystem. This system is cost effective ,multiple usage and deployed usingtrending IOT ,which is more efficient.
This system will reduce accidents which oftenhappen at the traffic signal intersections because other vehicles have tohuddle to give way to the ambulance services. This life saver project must beimplemented in the traffic forums to aid the public in good manner VI. FUTURE WORK: We are thinking to extend our ideaby implementing shortest location and way to hospital, to treat patients andalso alert the recommended Doctor in that hospital by providing initial medicaldetails of patient like BP, blood group, heart rate, etc..which will merit thetreatment more comfortable and reduce the time delay.
Facility to store detailsof several patients over long periods of time can be provided in cloudenvironment. VII. REFERNCES:1 Paper on”Automated Emergency System in Ambulance to Control Traffic Signals using,7http://ieeexplore.
