Abstract: Background: The highway speed-density relationship is fundamental since it draws a direct connection to how a driver’s speed choice is influenced by the presence of nearby vehicles, however, in developing countries, the absence of lane discipline on most roads increases the frequent lateral movements and aggressive lane changes, yielding inefficient utilization of road width .Objective: This paper investigates the best model for presenting the speed-density relation for non-homogenous traffic due to the absence of lane discipline through evaluating a bunch of parametric (statistical based) and non-parametric (data-mining based) models for fitting the best speed-density relationship for traffic streams where lane discipline is absent. Results: Results indicated that exponential model produced the best fit followed by the extreme Gradient Boosting model with R2 of 91%, and 88% respectively. Comparing the exponential model with other models developed in Egypt, under no lane discipline conditions, indicated that sites with higher free flow speed experience relatively higher speed and lower density at capacity compared with sites having lower free-flow speeds. Furthermore, the lane capacity obtained from the exponential model was about 1750 pcu/h. This lane capacity is about 80% of the lane capacity reported in the Highway Capacity Manual (HCM) for homogeneous traffic condition. Although other models developed in Egypt represented different free-flow speeds, they resulted in about the same lane capacity. Conclusions: Based on these findings, the speed-density relation for non-homogenous traffic, in developing countries, is best presented by the exponential model. Alsoa factor of 0.80 – 0.85 should be used when applying the HCM procedure to estimate the saturation flow rate for non-homogenous traffic conditions, depending on the free flow speed on the road.

Abstract: Validation is an essential issue to any trust situated registering framework and furthermore a basic part in numerous security conventions. It is famously difficult for performing validation. Over a decade ago biometric has turned into a well-known zone of research in PC vision and a standout amongst the best applications. Biometrics has been broadly utilized and received as a promising confirmation strategy because of its preferences over some current strategies, especially, its protection from misfortunes brought about by burglary of passwords and brilliant cards. Be that as it may, biometrics presents its own particular difficulties, for example, being vital once bargained. Also, the utilization of biometrics presents protection concern. Basic biometrics like unique mark, discourse acknowledgment and facial acknowledgment have been utilized. The impasse agreement is discovered more mixes when on arbitrarily differing simple flags, for example, discourse signals or physical qualities like fingerprints. Due to the idea of the issue, not just software engineering specialists are occupied with it, however neuroscientists and analysts moreover. In the mid-1960s, researchers started take a shot at utilizing the PC to perceive human appearances. From that point forward, facial acknowledgment programming has progressed significantly.

Automobile Censoring and Chasing Method for Avoiding Accidents to Intensify Safety and Security
Ramya D, Santhiya Grace A, Devi Kala Rathinam, Sherin J, Shilpa A, Rajkumar Y
Abstract: Though advancements in technology progressed to a greater extent, it is really difficult to control the vehicular accidents and hazards especially in the metropolitan cities. Due to the malign construction of roads and poor quality design of roads vehicles the accidents are more prevalent. To face these circumstances an innovative vehicle censoring and chasing ideology has been proposed and structured for the ambition of censoring the automobiles which are gripping from one location to another to give safety and security. The proposed methodology encompasses existing technology by means of Embedded C Programming language and ARM7TDMI-S unit is developed for the practical appearance of loading data in the database. It encompasses GPS and GSM for vehicular censoring and chasing including SIM800 which acts like a mobile phone with its unique phone number. It can transmit voice, SMS, and data information with low power consumption. The GPS gives current location of the automobile, GPRS sends the current chasing data to the server and so an active SMS gets generated and sent to the riders of the automobile. This method is implemented in the interior of the vehicle whose area is to be resolved on the web page and administered at actual time. If the owner or the driver drives in bad course like drowsiness or drunken, the processor caution by producing a sound through alarming sensor that produces a beep sound. The proposed method completely looks after the driver’s care by avoiding from the hazards.

Recycling of Industrial Waste Water for the Generation of Electricity by Regulating the Flow Control Sensor using IoT
Rajkumar Y, Kaviyaraj R, Karthika M S, Jeni Narayanan L. A. Saleekha, Ramya D
Abstract: The paper focuses on generating the renewable energy source from industrial waste water effluents. Utilizing the industrial waste water in order to generate electricity, a flow control sensor has been installed at the outlet of the tunnel which passes the waste water to the turbine. As per the need, the generation of electricity varies with respect to the flow through the use of flow control sensor. The generated electricity is then used for powering the street lights, gardening and run-way paths, during night time. The flow control sensor when integrated using IoT and cloud storage facilitates efficiency and scalability thereby providing massive utilization of energy usage.
