From Garden City to
Black City The Motorization Index(MI), number of vehicles per thousand, measures the intensity of vehicles in the city. According to the study, within a decade the MI has nearly doubled in Bangalore. Every 3rd person in Bangalore now owns a private vehicle, and that is a conservative estimate since, MI does not include migration of persons with their vehicles from other parts to Bangalore. While Bangalore has only 0.29% of KA's area and has only 4.8% of the road length within the state, Bangalore accounts for 40% of the total vehicles registered in KA. ![]() |

Availability of such a massive number of vehicles results in violation of individual spaces thus contributing to accidents. The resultant offshoot of such a high automobile growth along with supply intensive actions of the government is accidents. |

Accidents Bangalore contributes 18% of total accidents in KA and is one of the most accident-prone cities in India. According to the study, fatalities in Bangalore are relatively less when compared to the rest of the state because of the availability of hospital facilities near the location of accident. According to the study, while the statistics about the number of accident deaths is reliable, the number of injuries is highly under reported. |

The above table shows that
Bangalore has a prominent share in the total number of accidents
occurring in Karnataka. The number of accidents & deaths may be
showing a decline in trend but still the number is very high when
compared with other cities.

Mode Split of Accidents ![]() |
|||||||||||||||||||||||||||||||||||||||||||||
1. Car is the main accident-prone mode in Bangalore. 2. Public Transportation/Bus is the safest mode for transportation but ingress and egress movements are risky. 3. The Share exposes the issue of vulnerable groups (Pedestrian/Cycle). The police do not consider them in the accident mode share, as they are the most affected ones. If an accident occurs between a car and a pedestrian, whoever the culprit may be, the accident gets registered in the share of car and the death/injury is mainly taken by the vulnerable group. In an accident between two modes, the more affected party is not included in the share while the larger mode is considered in share. 4. Other Mode share is 19.5%. Such a high share is due to presence of Truck share and unknown hit and run cases. |
|||||||||||||||||||||||||||||||||||||||||||||
Vulnerable Groups Vulnerable group consists of pedestrians, school children, aged people, people using non-motorized traffic, public transportation and bicyclists. Pedestrians account for only 16% of all the trips in Bangalore but account for 40% of all the fatalities and 31-37% of all the injuries. School children constitute approximately 8-10% of total road accident fatalities. ![]() |
|||||||||||||||||||||||||||||||||||||||||||||
The society’s vulnerable group (Public Transportation users) mainly constitutes the pedestrian mode share. They are virtually exposed and have to compete with the traffic to gain space. |
|||||||||||||||||||||||||||||||||||||||||||||
Accident Patterns The data gathered by the authors show that nearly 36% of accidents occur in Night (18.00 pm-6.00 am). |
|||||||||||||||||||||||||||||||||||||||||||||
Such a high percentage in night times should be viewed in perspective of alcohol usage, less percentage of illuminated roads, lack of enforcements and availability of ample road space with no congestion. For proper accident analysis, speed and geometric design issues need to be highlighted. Urban roads in Bangalore face a peculiar design lacuna, which can be named as sinusoidal speed phenomenon highlighting gross extremities in operating speeds for the same stretch of road during different periods, which needs proper investigation. The high volume of traffic during peak hours allows very poor LOS with hardly any room to maneuver. During these periods there may be more accidents due to violation of individual spaces and generation of traffic shock waves but the accidental severity would be less because of relatively lower speeds (accidents due to heavy vehicles are exception). The accidents are more of injury/vehicle damage types, which induce further incident congestions. The off-peak hour’s accidents are more severe type, which makes an entry in official records. Further the design speeds of urban roads are dictated by restricted road space, high number of junctions with poor road furniture. The design and operating speeds of such roads are in order of 20-60 kmph. Ever availability of high congestion during peak hours leads to mental stress and frustration which the driver releases during night times by driving at free speeds thus generating sinusoidal speed profiles. Poor enforcement at such hour with safety risks allows driver to over-speed. |

PUB-City Bangalore accounts for the highest number of drunken driving cases in India. 44% of crash two wheeler drivers seeking medical attention were under the influence of alcohol. During weekends there is 12-20% increase in accident death probability. The study also point out that poor traffic sense prevailing in Bangalore is one of the chief contributors to high accidents. In 2005, 77% of vehicles have officially violated traffic regulations and fined at least once. At the same time with an enforcement density of 0.29 per kilometer length of the road, there is a serious lack of enforcement strength in Bangalore. |

Accident Costing |
|||||||||||||||||||||||||||||||||||||||||||||
One of the most contentious topics in Traffic Engineering is the case of Accident Costing. The Tools utilized by the researchers for accident costing are Human Capital Approach (Gross Output Method), Net Output Method, Life Insurance Method, Court Award, and Willingness To Pay Approach. The Human Capital method is mainly adopted in developing countries as the basis for calculation of Accident Costs. Road User Cost Study and report by Tata Consultancy services are the most recent government backed report available in this topic. The reports value the cost of road death to Rs 210554 (1990 prices) and Rs 535489 (1999). Such a low cost of life should not be considered in the analysis. The Gross Output method and other methods are a sort of discriminatory tools. These methods judge the cost of life in view of its economic status and future output. The tool can become discriminatory if randomly used and applied to calculate accident costs. The Cost of life should never be judged by the government in view of its economic status while considering the funding of infrastructure development. Also there is a serious lacuna in government compensation methodology, the accident victims in a railway crash are paid very less compensation whereas the victims in an air crash are paid higher compensation on the basis of gross output/willingness to pay/Court award. The Court award in India for road accident deaths varies up to 40 million rupees. In road sector also there is variable accident compensation across the modes. There is variable compensation paid for other type of accidental deaths, though from a nation’s perspective, all life should be measured from a common datum as they carry equal rights. In fact there is a Supreme Court Hearing (India) (Case involving Zoremsangi) where it has considered the age of claimant and not the age of victim as the basis of accident compensation along with other variables such as income of the deceased and other relevant factors like loss of love and affection, mental shock and others. Also for example in one more case involving Babu Rao, the Court disallowed compensation to a injury victim who died later after five months due to some other reason stating that “the claim of compensation for injuries was a personal tragedy and such claim dies with the death of the injured, unless the legal heirs are able to establish that the death was due to injuries sustained by the deceased claimant”. The High court later took sympathetic view because of the lacunae in compensation methodology and directed the government to pay 50,000 Rs as compensation. The varied rulings of the court virtually shake the fundamental understanding of accident costing phenomenon. The author recommends use of a fixed value of road fatality at least while estimating economic loss due to road fatalities as the possibility of accident death was present and that it was only a chance that a particular person died instead of some other person. As the government generally distributes the development fund based on economics along various sectors located at geographically varied locations, such an exercise would eradicate the bias associated with accident costing and compensation to other types of deaths. |

Government Action/Reaction |
|||||||||||||||||||||||||||||||||||||||||||||
The most common myth of accident being a random, unintentional, or predestined; i.e., unavoidable should be dispensed with. The accidents are no doubt an offshoot of motorization phenomenon, but they are never unavoidable. There is urgent need to introduce VISION ZERO concept. In Bangalore city by the government agencies in order to reduce the escalating economic loss due to fatality. Forgiving roadside concept is still alien considering the present context in Bangalore. The government has used the traditional traffic engineering “3E” concept for solving Bangalore accident problems. The tool of Engineering, Enforcement and Education has not yielded dramatic reductions, which is the need of the hour in view of bleak future. The government has now embarked on prestigious BTRAC project whose motive is to reduce accidents by 30%. The project involves traffic management with ITS involvement with a budget of 350crores is one of its kind in India. It has a host of smart technology innovations such as smart signals, smart enforcement, smart information, smart safety plan etc. Operation Sanjeevani launched by the Manipal Institute of Neurological Disorders, is one of the post measures taken for reducing the accidental death by speedy and proper transportation of injured people to the hospital. A Comprehensive Trauma Consortium (CTC) was launched when it was found that the pre-hospital care can save many lives. It provides Para-medical help with GPS connected ambulances for all medial emergencies and accidents and liaises with 22 hospitals (all of which have been accredited by a qualified team) to ensure that the best help is available to the victim within the "golden hour" of the accident/emergency. With 83.5% of accidents occurring in India (84% in Karnataka) being due to Driver Error, proper driver education strategies would help reduce accidents. Bangalore has the highest per capita income in India indicating good education across the stream. But the traffic education is still at the nascent stage considering high number of violations and road rage cases. |

Conclusion |
|||||||||||||||||||||||||||||||||||||||||||||
Usual adaptation of “3E” in Bangalore is not getting the required results. The slow implementation is generating smaller accident reductions. Things look gloomy in future considering the supply intensive actions taken by the government. Accidents may decrease due to relentless work done by the police but the accident severity is bound to increase with increase in traffic Speed while roadside safety Environment is still neglected. Finally it can be highlighted that Bangalore has the distinction of having the traffic with largest per capita income in India with full knowledge of having high accident risks but still has a very high number of traffic offenders indicating the willingness to take accident risks during the course of normal life thus debunking the classical traffic engineering theory and WTP approach. |
