Fig. 7. Viewing bus information In this paper, we have presented a smart bus tracking system. It is based on GPS, GSM, QR coding and Google’s map technologies. The proposed system, basically tracks the busses, estimates their arrival times at specific bus stops and informs the users through e-mails and SMSs. The system prevents passengers unnecessarily to wait at bus stops and enables them to use their time more efficiently.

The components and architecture of the proposed system consists of four stages as shown in Fig. 1. These are (1) scanning QR codes placed at bus stops and listing buses according to passengers’ desires, (ii) searching buses and/or bus stops and showing timetables, (iii) showing bus stops and routes on the Google map, and (iv) estimating bus interval time with machine learning algorithms and finally sending this information to users via SMS and/or e-mails. Each stage is detailed in the following subsections. Fig. 1. Architecture of web based smart bus stop system

Fig. 3. Contents of QR codes placed at bus stops We use QR codes for the purpose of providing locations of bus stops. QR codes contain bus stop location information such as latitude and longitude (see Fig. 3). When QR codes, which are placed at bus stops, are scanned by passengers, they can view estimated bus arrival time, and bus’s current location. Users can also view routes of selected buses on the map.

subsid optica code capab iary, Denso Wave in 1994. Data is encoded in QR lly readable format using QR code generators. So, QR can be captured and decoded by smart phones. It is e of handling up to several hundred times more information than the traditional bar codes unlike conventional bar codes are only capable of storing twenty digits. According to dif ferent versions of QR code, distinct information storage capacity may be used (see Fig. 2). The cost of information transfer via QR code is extremely low as compared with other technologies where specific hardware is always required [12]. Consequently, QR code is the most widely used information container that can be applied to different printed materials (e.g., posters, books or magazines) and places (e.g. bus stops, store windows, etc.).

Fig. 6. Showing bus stops and routes on the Google map Attribute “reason” gives the highest gain of 1.171 bits in our example, and therefore this attribute will be selected for the first splitting. After splitting on best attribute, we add other nodes as children of best attribute node and we do same operations recursively. Each leaf’s path can be transformed into an IF-THEN rule to make a decision tree model more readable.
