Moreover, fleet operators would like to ensure safe trips to their customers. This can be accomplished by tracking and maintaining a history of the driving patterns of the drivers employed by them. Further, individuals would also like to assess their driving style and become safe drivers. In this regard, a cost effective solution for detecting road artifacts as well as tracking the driving behavior of drivers using smartphones has been developed. The solution relies on the sensors installed on the smarphone only thereby making it cost effective. Although the system does not use commercial grade sensors, yet our accuracy numbers indicate that the solution is good enough for commercial deployment.Few of the very popular methods based on smartphones, use data collected through sensors for user activity detection in various environments (Indoor localization 3, traffic detection Using smartphone to collect data is a promising alternative because of its low cost and easy to use features in addition to its potentially wide population coverage as probe devices. This paper proposes a non-intrusive method that uses sensors present on smartphones, which most of the people are expected to carry, thus obviating the need for any specialized hardware to be installed in vehicle or on the roadside. Here, we have extended various prior studies to improve the algorithms based on using accelerometer, GPS and magnetometer sensor readings for traffic and road anomaly detection. Specific interest is in identifying braking events - frequent braking indicates congested traffic conditions and anomalies on the roads to characterize the type of road. Using driving behavior analysis including hard acceleration/deceleration, braking, turns, frequent lane changes, etc. we propose a way to derive driving score considering multitudes of parameters, which makes it to be more accurate than any prior work. Since, we have a large number of commuters who daily travel on road, that makes this solution even more important and significant.An android application (S-Road Assist, already on Google Play Store) is developed to collect data from various sensors present in smartphone like accelerometer, gravity, magnetometer and location (GPS) sensor. Application does support the driving mode detection and automatically launches itself to collect and sink data to servers. Driving mode detection algorithm makes use of 3-axis accelerometer values by calculating root mean square acceleration on the device applied every time the phone changes orientation, whereas we apply the re-orientation algorithm over a data window, say every 1 sec. Re-orienting sensor values over all the windows takes care of the impact on the sensor, if it stays for a longer duration, for instance if user takes up a call.A complete working system with above mentioned approaches and proposed solution is already in development. Android application named “S-Road Assist” can be found on Google Play Store. The objective is to help improve driving experience and assist users in improving driving skills. Events (road artifacts), that are detected by the analytics engine after the analysis of recorded data, are pushed back to the smartphone using the same application for producing notification alerts of upcoming events along the route in advance. Big data analysis or crowdsourcing is the key to overcome the compromises made during data collection, preprocessing or detection. To emphasize further, solution obviates the need for any specialized hardware and relies only on the smartphone, which may or may not be docked inside the vehicle (can be in any arbitrary orientation or position), thereby making the proposed solution cost-effective. Building a system using the proposed techniques will surely help in avoiding many road casualties and improve the driving experience by many folds. Smartphone here act as an asset to record data to identify road anomalies which later is notified to the user, thus turning the smartphone into a “saver phone”.
