Automatic Pre-collision warning by Stress Detection and fastest Rescue alert
Abstract— Vehicular traffic collisions have become a major health concern nowadays. Traffic accidents are increasing every year with increase in number of vehicles. Various techniques have been proposed previously to assist the injured people in road accidents. It includes automatic estimation of severity about collisions and also to deploy emergency services to affected people. Present scenario gives the capability to notify them based on the concept of knowledge discovery on databases (KDD) and data mining processes. The proposed idea here is a novel and intelligent system to introduce a pre-collision warning system inside vehicles. This continuously monitors the driver status by detecting emotions by using sensors. It checks the pulse rate of the driver and gives alert when he is under stress and gives the message in display. By integrating Android application, the voice alert is provided to the passengers hence enhances more safe and comfort drive. Thus the work proposes a system that reduces the chance for accidents. Further in the case if crash occurs, the system automatically gives the information to the nearby rescue home within no time. The data is transmitted with the help of a wireless communication network and reaches the control unit. The control unit may be fixed at the hospital or nearby rescue center. The data sent includes time, location, severity of collision thereby ensures properly and timely assistance to the persons injured in collision.

The initial base run showed high Y-displacement of 772mm and high chest deflection. Reinforcements like added beam members reduced displacement to 600mm. However, injury values like CSI of 318 and pelvic acceleration of 589g still exceeded standards. Further improvements like side airbags and strengthened A/B pillars were proposed.
Roof Crush
This document summarizes the results of a simulation analyzing the structural performance of a truck undergoing roof crush. The simulation shows the roof experiencing over 142mm of maximum deflection on impact, with outward bulging of the external door panels. Using high-strength steel for structural members in a subsequent simulation reduced the deflection. The total energy during impact initially spikes then gradually increases, and the simulation ends with displacement of the A-B pillars and roof cross members, and buckling observed.
Zero Turn Radius Presentation - Team Panache
The document describes the design of a zero-turn radius system for a John Deere 5065E tractor.

Vehicle technology has increased rapidly in recent years, particularly in relation
to braking system and sensing system. In parallel to the development of braking
technologies, sensors have been developed that are capable of detecting physical obstacles,
other vehicles or pedestrians around the vehicle. This development prevents accidents of
vehicles using Stereo Multi-Purpose cameras, Automated Emergency Braking Systems and
Ultrasonic Sensors. The stereo multi-purpose camera provides spatial intelligence of up to
50 metres in front of the vehicle and there is an environment recognition of 500 metres.
Cars can automatically brake due to obstacles or any hindrance when the sensor senses the
obstacles. The braking circuit function is to brake the car automatically after receiving
signal from the sensors. All cars are competent in applying brakes automatically to a
maximum extent of deceleration of 0.4g. Integrated safety systems are based on three
principles. They are: collision avoidance, collision mitigation braking systems and forward
collision warning.

Traffic Density Control and Accident Indicator Using WSN
Now a day’s many of the things get controlled automatically. Everything is getting controlled using the mechanical or the automated systems. In every field machines are doing the human works. But still some area is controlled manually. For example traffic controls, road control, parking controlling. Keeping these things in mind we are trying to develop the project to automate the traffic tracking for the square. To make any project more useful and acceptable by any organization we need to provide multiple features in a single project. Keeping these things in consideration proposed system is less with multiple methodologies which can be used in traffic control system It is important to know the road traffic density real time especially in mega cities for signal control and effective traffic management. In recent years, video monitoring and surveillance systems have been widely used in traffic management. Hence, traffic density estimation and vehicle classification can be achieved using video monitoring systems. In most vehicle detection methods in the literature, only the detection of vehicles in frames of the given video is emphasized. However, further analysis is needed in order to obtain the useful information for traffic management such as real time traffic density and number of vehicle types passing these roads. This paper presents emergency vehicle alert and traffic density calculation methods using IR and GPS

Congestion control & collision avoidance algorithm in intelligent transportation
This document discusses algorithms and a proposed system for congestion control and collision avoidance in intelligent transportation systems. It proposes an open source model architecture with centralized routing nodes at intersections that communicate wirelessly with vehicles. The routing nodes calculate distances and assign speeds, lanes, and times slots to vehicles to avoid collisions when crossing intersections. Vehicles are fitted with sensors and computers to dynamically control acceleration, braking, and steering based on data from the routing nodes. The goal is to develop a system using DSRC and GPS to safely route autonomous vehicles from any starting point to destination without collisions.
Driver-less cars by avaneesh shuka
Driverless cars use automatic control systems to navigate roadways without human assistance. Sensors detect road conditions and obstacles while navigation systems plot routes. Motion planning software controls acceleration, braking, and steering to maneuver safely through traffic. Early technologies like ABS, cruise control, and automated guided vehicles demonstrated autonomous vehicle components. The 2007 DARPA Urban Challenge advanced driverless car capabilities by having vehicles navigate a 96km urban course obeying all traffic laws. While autonomous vehicles can increase road safety and capacity, cybersecurity risks and sensor failures present disadvantages requiring further development.
An Approach to Improve the Railway Crack Detection in the Tracks by Automated...
This document proposes an approach to improve railway crack detection in tracks using automated engines. It involves designing engines that are automated and connected to RF rays. The system uses two nodes: a track side node mounted on posts along the tracks every 300 meters, and a station side node. The track side node detects cracks using GSM if the RF rays do not pass between posts due to a crack. It then sends a message to the nearest station and engine. The station side node communicates information to incoming trains and displays it for passengers. This automated system aims to improve railway safety by detecting cracks in tracks.
An Approach to Improve the Railway Crack Detection in the Tracks by Automated...
Abstract : Today in the real time world, so many type of transports are available like, flights, trains, buses, but majority of the people doing their travelling in trains only because due to less amount of charge for long time journey and at the same time it is more comfortable also. For those people we have to provide the safety journey, so the government has to take the responsibility for this. Although the government has taken necessary steps to safe journey but due to some reasons the accidents will happens. One of the major accidents in the railways networks are occurs due to track side faults. The track side fault means it will occur as natural or artificial. To avoid this we are going to design the automated engine model. In this design the engine should be automated and it is connected to the RF Rays. The automation techniques are based on two nodes, Track side node and Station side node. The proposed scheme has been modelled for Automation Engines in the Indian railway networks alone. Keywords : Crack, Detection, GSM, Automation, Engines.
Driverless car
Driverless vehicles use sensors, navigation, motion planning, and actuation to operate without human assistance. Sensors like cameras and lasers detect surroundings, navigation software guides the vehicle along a plotted route, motion planning algorithms determine safe movements around other objects, and actuation systems like brakes and steering execute the vehicle's movements. While the technology provides benefits like safety and increased road capacity, security issues around hacking pose risks if not properly addressed.
Improvement of Traffic Monitoring System by Density and Flow Control For Indi...
The growth and scale of vehicles today makes management of traffic a constant problem. The existing traffic control system works based on a timing mechanism, meaning an equal time slot is provided for each junction. This is inefficient for non-uniform flow of vehicles. Hence there is a need for a system which is adaptive in nature. Routes should have an option of being granted more time slots depending on the requirements for the given route. This paper proposes a traffic congestion control system which would be adaptive in nature and provide time slot to each route based on traffic density.

Intelligent Collision avoidance and monitoring system for railway using wirel...
In the current railway systems, it is becoming ever more necessary to have safety
elements in order to avoid accidents. One of the important causes that can provoke serious accidents
is the existence of obstacles on the tracks, either fixed or mobile. This project deals about one of the
efficient methods to avoid train collision and obstacle detection. A GPS system is being used to
pinpoint the location of faults on tracks. The project presents a solution, to provide an intelligent
train tracking and management system to improve the existing railway transport service. The solution
is based on powerful combination of mobile computing, Global System for Mobile Communication
(GSM), Global Positioning System (GPS) technologies and software. The inbuilt GPS module
identifies the train location with a highest accuracy and transfers the information to the central
system. The availability of the information allows the train Controller to take accurate decisions as
for the train location. Positioning data along with train speed helps the central system to identify the
possible safety issues and react to them effectively using the communication methods provided by
the system.

Impromptu ideas in respect of v2 v and other
The document proposes using a distributed and cooperative communication approach for controlling future robots. A distributed approach would provide robustness over a centralized system by avoiding single point of failures. However, the environment is unpredictable, so cooperative mechanisms are needed like storing commands that can be used when needed. The document also suggests combining centralized and distributed systems by allowing the centralized system to change dynamically. This would decrease the probability of failure enormously. It then discusses using concepts from network science like scale-free networks to help define fast routing protocols for vehicle communication networks where nodes change positions quickly.

Vacuum circuit breaker
Vacuum circuit breakers use vacuum to extinguish the arc when opening contacts. They have fixed contacts, moving contacts, and an arc shield mounted inside a vacuum chamber. When a fault is detected, the contacts separate and the arc is quickly extinguished in the vacuum. This allows vacuum circuit breakers to reliably interrupt high fault currents. They have advantages over other circuit breakers like being compact, reliable, and able to interrupt heavy fault currents without fire hazards.
Stepper motor
A stepper motor converts electrical pulses into discrete mechanical movements of its shaft. The shaft rotates in discrete step increments that correspond directly to the sequence and frequency of input pulses. There are three main types of stepper motors: variable-reluctance, permanent magnet, and hybrid. Stepper motors provide controlled movement and are well-suited for applications that require control of rotation angle, speed, position, and synchronization. They have advantages like full torque at standstill and excellent response to starting, stopping, and reversing.

Anti collision technology of crashless cars
- 1. - ANTI COLLISION DEVICES & THE CONCEPT OF CRASHLESS CARS 1
- 2. Anti Collision Device(ACD) Network-”Raksha Kavach” A train collision preventing system Invented by Konkan Railways, over a period of 90 days. Meets the challenges of Railway Transport safety. India the only country to possess such a technology. 2
- 3. The Technology… Based on radio communication, Microprocessors and GPS Technology. Enables trains to automatically assess each other’s course and prevent an imminent head-on collision. Also prevents side and rear end collisions. Intel 80386 Microprocessor , integrated radio modem works on real time operating system. 3
- 4. Working… 4
- 5. The ACD Network Works on engine battery system, and also powered by solar technology, if required. A Network of ‘on-board’ (Locomotive and Guard) and ‘track-side’ (Station, Level Crossing, Loco shed, Repeater and Sensor-based) ACDs that work on the principle of ‘Distributed Control Systems’. ACDs interact en-route with each other through radio communication within a radial range of 3 Kms. On-board computers use input from GPS system for determination of Train location, Speed, Course of travel and Time. 5
- 6. Mobile and stationary components of ACD Network exchange information and take decisions based on train working rules. If 2 ACDs are deemed to be at a risk of collision, the ACD system activates automatic braking operation to 6
- 8. Functions.. Detection & Prevention of Head-on, Rear-end and Side Collisions – A UNIQUE feature even when a train is not protected by a signal, as in a block section. ‘Train Approach’ Warning for road users at Level Crossings both manned and unmanned. Station Approach Warning to Drivers - Can result in saving of manpower. Manual SOS functionality available for Drivers, Guards and Station Masters. Auto Brake Test – Generating braking 8
- 9. Efficacy Of ACDAnalyzed For Indian Railways 82 % train collisions ‘preventable’ by this system, during the analysis period of five years. Rest cases ‘non preventable’, based on other factors. Phenomenal increase in the volume of trains running on the same track. 9
- 10. Crashless Cars Next generation automotive safety technology to make driving safer and faster. Leading car makers already offering advanced technologies in top-end cars. Heavy investment- key obstruction in making it popular. Also a possibility of robotic vehiclesdriverless cars. 10
- 11. Existing Safety Features.. Anti-lock Braking Systems(ABS)- improve steer ability and hasten deceleration. Traction Control System(TCS)- improving overall vehicle control. Enhanced Stability Control(ESC)- prevention of de-alignment.- results in 30% less single vehicle crashes. Latest technology uses the above in addition to some newer techniques. 11
- 12. Developments.. Use of sensors, cameras , radars to monitor incoming and surrounding traffic. Networking between the cars’ computers to take quick decisions. Collision Warnings- cruise control systems. 12
- 13. A long-distance, 77-gigahertz, microwave radar sensor monitors out to 400 to 650 feet ahead. Shorter-range, 24-gigahertz, radar unit scans several tens of meters up front. Wide-angle video cameras recognize objects about 130 to 165 feet away Warning system in case of danger- prepares for emergency braking. 13
- 14. Automatic Braking & Lane Departure Systems System automatically hits the brakes or steers cars back into their lanes to avoid accidents altogether. Use of laser beams to look for reflections from objects upto25 feet away. In case of driver’s inaction, applies brakes automatically. Warning the drivers in case of drifting from lane- appropriate braking to re-align the car. 14
- 15. 15
- 16. Other Devices.. Blind Spot Cameras- cameras on the outside of the vehicles that can identify objects normally hidden from view. Use side-mounted ultrasonic or radar sensors. Backover Detection Automatic Pedestrian Recognition 16
- 17. An Example… 17
- 18. Issues With Automation Cost factor- major obstacle. Multiple warnings overlap. Spurious warnings- cry wolf. Prioritizing attention. Driver’s role gets diminished- not much acceptable. 18
