Vehicle Structures Systems, 9(1), 219-223. doi10.4273/ijvss.9.1.06 incomingThe use of existence transport is vital to the productivity and independence of visually impaired people. Supporting visually impaired people to use the public transport mickle increase their chances of educat ion and employment and reduces the financial shoot on their families. In most physical environments, the visually impaired people have difficulty in accessing information about bus break aways, terminals, vehicles, schedules, maps, and directories, which stop them from using the public transport effectively. Knowing the location of the bus stop and the time when the bus arrives argon the difficulties faced by the visually impaired people. Some position navigation systems have been developed to solve the worry of locating bus stops. Advanced public transportation services (APTS), including bus dynamic information exhibit method with the Global Positioning System (GPS) technology, have been developed by many countries.APTS 1 helps with the bus-stop voice reporting systems to picture more information for visually impaired people about the reach of the bus which they want to board. Some APTS combined special handling devices were knowing to provide dynamic information for visua lly impaired people. In Taiwan, the capital of Taiwan city government utilized an experimental system named broadcasting bus, that announces the bus take upon arriving at the bus terminal, to serve the visually impaired in 2002. The APTS named e-bus system started to be deployed in Taipei city since 2005 3. Using these technologies the number and the waiting time of the buses were shown on the light-emitting diode (LED) screen at the swank bus stops using GPRS facility. Only 20 percent of bus stops are planned to build. A inspect of 400 passengers in 1998 revealed that the smart bus stops are not sufficient when furnish only with the voice reporting system because the voice information unordered when many buses approached the same terminal at the same time which was a disadvantage of using many-to-many communication. The APTS with bus-stop voice reporting system and handheld devices ability not provide a solution to this important issue.A survey showed that it would be very he lpful if somebody could alert bus drivers about their boarding on buses. Various systems have been developed for visually impaired to communicate with bus drivers. Mehra et al. developed a user-triggered bus identification system in 2010. The user could select a particular bus and send requests by user module, and past a small LED starts waver in the drivers control panel. The system offered only one-way communication. Bischof et al.developed a wireless local area ne twork (WLAN) communication system named NAVCOM. The authors proposed that blind people need a feedback to make sure whether the bus drivers get the original message. An other(a) bus identification system designed by El Alamy et al. involves a bus station controller to identify users and send signals to buses with radio frequency. This system will say the information of the bus number when in that location is a 2-meter length between the bus and the bus station.In Taipei, bus drivers are forced to leave the bus sto p as short as affirmable because most time several buses arrive at the same bus stop simultaneously. Visually impaired people are often ignored at bus stops if no one informs bus drivers about waiting passengers 2. The aim of the present study is to reduce the difficulties faced by visually impaired people while taking buses with interactive wireless communication design. The interactive feedback system allow visually impaired people and bus drivers to receive the familial signals from each other and improve the success rate of boarding correct buses 4.Project motoThe moto of our check is to help the visually impaired people to transport easily and in like manner we added some extra features through which the deaf could besides be benefited in bus transport. So our count on is like a knife which is bully at two the ends and is going to help the people in two ways. Adults too can know which bus is going to arrive at that moment. So all the people in the society can use this system. We are very interested in doing such a project for our society. There are two modules user module and bus module. The user module will be handled by the user or it can also be placed as common in the bus stop also, so that all the people can use it and then if it is handled by single user alone then he or she can only use it. The bus module is fixed in the place where the driver can notice it.Hardware designFor the reading of our project, we use two modules. whizz at the bus driver-bus moduleOne at the passenger-user moduleHere we are using both sender and receiver at both the module. The process, here is that the passenger waiting at the bus stop should switch on the passenger module, it sends out the signal, that signal is received at the receiver of the bus module. Then automatically the qui vive sound will be produced and then the LCD will display that there is a passenger is waiting at the nearby bus stop, and then an LED will be glowing there. There are many partic les that are utilise for this process. Two types of ICs are used one is cryptogram IC and the other is decoding IC.Fig. 1 Intel Galileo Gen-2Here the signal is transmitted and received using RF contagion and receiving modules. For various indicating purpose we use different types of LCD such as warning LED to glow while the buzzer buzzes and the power LED to indicate the positioning of the module whether it is in ON or OFF state. The main component of our project is Intel Galileo Gen-2 board which is used in Adruinio programming platform as shown in Fig. 1. The speciality of this board is that it can be used as a PC after installing an OS through SD card. It also has some special features that it can be connected to LAN and access internet, it has 20 digital pivot mans which can be used as remark/output and 6PWM output pins. We can also connect USB cable to it to tape drive programming to it. It works with a power supply of 7-15V DC input. The coding IC HT12E is a 18 pin IC as shown in Fig. 2 mostly used for Radio Applications. The main purpose of this IC is to convert couple input to serial output. It has 8 address pins and 4 entropy pins, used as an encoder. It has an active low enable pin and works on the voltage direct of 2.4-12V.Fig. 2 Encoding ICFig. 3 Decoding ICFig. 4 System framework of the user module and the bus moduleIn Fig. 3, the decoding IC HT12D is also a 18 pin IC and converts the serial input to parallel output. Which does the opposite process on the coding IC. Operates at the voltage level same as coding IC. The block diagram shows the components connection of both user and bus module.System developmentIn a sincere environment, the interaction between visually impaired people and bus drivers are many-to-many relationship rather than a one-to-one. For technological simplicity, in our system we used a one-to-one interactive communication system. The collision of communication data over the one-to-one interactive wireless communicatio n leads to the poor stableness and low accuracy of wireless communication. The signal communicates through two clean-cut frequency dance orchestras 434MHz and 315MHz. The interactive wireless communication system has two modules a user module for the visually impaired (Fig. 4), and a bus module (Fig. 5) for bus drivers. The hardware was developed according to the interactive design. The user module consists of a wireless transmission module (434MHz), a wireless receiving module (315MHz). The bus module consists of a wireless transmission module (315MHz), a wireless receiving module (434MHz). When the user module sends out a signal, it is transmitted through the 434MHz band to the bus module, which then sends reply through the 315MHz band to the user module. In this way by using different frequencies for transmitting and receiving signals, the problem of wireless data collision between users is avoided.Outcome esteemA basic requirement of this system is the wireless communication distance. If the wireless communication distances were shorter than buses stopping distances, conversely, if the wireless communication distance was too long, it was possible that the bus driver would have received the information from a waiting user too early. To avoid such situations, the maximum transmission distance of this system must be less than 100 meters. The outputs are displayed in an LCD which are taken snapshot for both transmitter in Fig. 5 and receiver in Fig. 6.5.1.

This system is flexible to any climatic conditions. Thus by using our project visually impaired people can use th e public transport facilities in an efficient manner.ReferencesA. Montarzino, B.
