INNOVATIVE CONCEPT OF DIGITALSPEEDOMETER AND SIGNAL INDICATOR

AT THE FRONT AND BACK OF THE VEHICLE

Varada Uday Bhaskar1

The frequency of traffic collisions in India is amongst the highest in the world. Driver andpassengers involved in an accident often end up with minor or major injuries and in occasionalcases sudden death. Road accidents have been and will continue to be one of the greatesthealth hazards. In spite of implementing strict measures like no alcohol consumption, no cellphone driving, good roadway design, slow driving at poor roads, safety signals, safety boardsand so on, Statistically it has been shown that the no. of death and injuries are increasing due toroad accidents every year in the whole world. This paper discusses on the idea of implementationof digital speedometer and Signal indicator at the front and back of the vehicle, which helps inreducing the road accidents to some extent.

INTRODUCTIONTraffic fatalities per unit population has been takenas an indicator of the health burden of road trafficcrashes on society at the city, regional, or nationallevel. At the individual level, what is ofconsequence is the risk of injury per trip, and thetotal number of trips is proportionate to thepopulation. Therefore, traffic fatalities per unitpopulation can be taken as a rough indicator ofrisk faced by individuals. The risk of being involvedin a fatal road traffic crash has obviously beenincreasing for Indian citizens over the past few

years. While some of this increase can beattributed to increase in the number of motorvehicles per capita in India, however, increasingvehicle ownership need not result in increasedfatality rates if adequate safety measures areimplemented. [1]

The total number of road accidents increasedby 2.5% from 4,89,400 in 2014 to 5,01,423 in2015. The total number of persons killedincreased by 4.6% from 1,39,671 in 2014 to1,46,133 in 2015. Road accident injuries have

also increased by 1.4% from 4,93,474 in 2014 to5,00,279 in 2015. Accident severity (number ofpersons killed per 100 accidents) has gone upfrom 28.5 in 2014 to 29.1 in 2015. The analysis ofroad accident data 2015 reveals that about 1374accidents and 400 deaths take place every dayon Indian roads. It further reveals that 57 accidentstake place and 17 lives are lost every hour on anaverage in road accidents in our country.

During 2015, a total of 5,01,423 road accidentswere reported by all States/UnionTerritories. Ofthese 26.3% (1,31,726) were fatal accidents. Thenumber of persons killed in road accidents were1,46,133 i.e an average of one fatality per 3.4accidents. The number of road accidents, roadaccident fatalities and persons injured in roadaccidents in India during 2005 to 2015 is shownin Table.

According to the Department for Transportstudy, Contributory Factors to Road Accidents,2005, the main causes of accidents are as follows:

• Failure to look properly – 18%

• Failure to judge another person’s path/speed– 10%

• Being careless, reckless or in a hurry – 9%

• Poor turning/manoeuvring – 8%

• Loss of control – 8%

• Going too fast for conditions – 7%

• Slippery road – 6%

• Following too close – 4%

• Sudden braking – 4%

These figures are drawn from accidents wherethe police attended the scene and a contributoryfactor was reported. But just looking at the above,it’s clear to see that some actions can be takento try and reduce the risk of having an accident.

Over view of the IdeaIt is observed from the Department of Transportstudy due lack of Proper looking, it resulted in18% of accidents in 2005 the value increased insubsequent years. The idea is to identify thespeed of the moving vehicles. When the driver

of his vehicle identify the speed/velocity of the front,side and rear vehicles he can be in a safe zone. Itmeans he can properly analyse the relativedistances between his vehicle and other vehiclesand see it clearly without any assumptions. Thisavoid accidents to some extent.

If the vehicles are equipped with Digitalspeedometer Indicator and Signal system at frontand rear of the vehicle the below shown accidentscan be avoided.

Assume Two Vehicles A and Vehicle B areMoving Relative to Each Other:

Vehicle A and Vehicle B moving inline in singleline road:

Assumptions: Both vehicle A and vehicle B aremoving in high speed

Both vehicles are moving in oneline and one direction of the Road.

When vehicle A is coming from very far distancewith a high speed say 100-150 km/h, asit approaches vehicle B which is moving at80-120 km/h. The driver of the vehicle A mayassume that the vehicle B is also moving at highspeed, but as the driver of vehicle A does notknow exactly with what speed the driver of vehicleB is moving there are possible chances of havinga clash as shown in Figure.

Vehicle A and Vehicle B moving in oppositedirection in single line road:

Assumptions: Both vehicle A and vehicle B aremoving in High speed

Both vehicles are moving in single line andopposite direction of the road.

The same is the case with vehicles moving inopposite direction in single line road. When Vehicle

A is coming from very far distance with a highspeed say 100-150 km/h, as it approaches vehicleB which is moving at 80 -120 km/h. The driver ofthe vehicle A may assume that the driver of vehicleB is moving at low speed and he can divert theway, but as the driver of vehicle A does not knowexactly with what speed the driver of vehicle B ismoving there are possible chances of having aclash as shown in Figure.

The clashes can be avoided as shown in fig.to a great extent if the drivers know the relativespeed of other vehicles moving beside theirvehicles.

Advantages of the Idea:

1. All the people (old, middle and teens) who areunable to see properly and who are still drivingcan easily identify the speeds of other vehiclesand be in their safer zones.

2. Implementing this idea helps in judgment ofidentifying the accused and the victim in roadaccidents as the digital speeds can be noteddown (At the time of accidents the Digitalspeedometer will be stopped with the valuesjust before the accident has took place).

3. This idea is inexpensive which helps all thepeople, as this idea can be implemented inthe vehicles at low cost. ComparativelyImplementing auto pilot or obstacle detectorsin the vehicle is very costly, which cannot beaffordable by a normal person.

4. The pedestrians can move to their safe zonedrastically when this idea is implemented.

5. There are possible chances of failure ofobstacle detectors or auto pilot but there areless chances of failure of digital speedometerindicator at the front and rear of the vehicle,as the indicator starts as the vehicle starts.

6. The implementation of this idea is most usefulfor night time drivers.

IMPLEMENTATION OF THE IDEADigital speedometer at the front and rear of thevehicle.

Digital speedometer at the front and rear of thevehicle along with the indicator signal.

CASE STUDY1. On 3rd Oct, 2016 in a place Pordenone, Italy

the very frequent case of the so-called “pileup”,i.e one that involves clash of several cars one

behind the other has occurred incurring heavymaterial loss as shown in the Case Study 1.

In this case it has become difficult to identifythe faulty.

2. Reported in the year March 16, 2016. Multiplecar pile-up is one of the most frightening anddestructive events that can occur on the road(Case Study 2). Unfortunately, these crashesare all too common, especially during thewinter: a USA Today analysis last year foundthat 57 reported pile-up accidents occurredbetween November 2014 and March 2015 inthe United States.

5. India not only has the dubious distinction ofhaving one of the worst road accident recordsin the world, but that these are taking more andmore young lives, particularly of school children.Road accidents have left nearly 70 children deadand many injured since the start of 2013, a NGOhas said. More than 60 students were also

injured in 11 accidents spread over seven statessince January 2013 till July this year. In allinstances, the victims were travelling in schoolbuses which were either hit by other vehiclesor trains or rolled down mountain slopes. Theaccident shown in the (Case Study 5) 25th July,2014 occurred in New Delhi, India. [7]

Scope of Future Study

• Implementation of the idea on the vehicles inpractical scenario

• Electrical design which immediately stops thedigital speedometer at the same value whiledriving just before accident Occurs. This helpsto know the speed at which the vehicles havemoved at the time of accident.

• Aesthetic design of the speedometer andsignal system.

• Design of the magnifying glass cover on theDigital speedometer and signal system whichhelps drivers to easily read the values even ata distance of 100m to 200m and more.

CONCLUSIONThis paper concludes the idea of implementationof digital speedometer indicator at the front andback of the vehicles along with the signal system,which identifies relative speed of the other vehiclesand help the drivers to operate the vehicles inSafe zone.
