Chennai vehicle population has been accelerating steadily from 600,000 in 1992, to 1.3 million in 2001 and 3.64 million in 2012. Daily, about 1500 new vehicles hit the roads, with two-wheelers constituting more than 75 percent of them. However, registration of new cars is also on the rise. Chennai vehicles constitute one-fourth of the 17.5 million vehicles across the state of Tamil Nadu. The state has more two-wheelers (13 million). Two-wheeler account for 78 percent of all vehicles in the state, while cars add up to 14 percent. Accounting to a survey conducted by the city traffic police in 2012. More than 70 percent of the population should be using public transport, but less than 40 percent regularly use it.

Chennai city is more than 70 percent of the population should be using public transport, but less than 40 percent regularly use it. Owing to the high traffic density, the average bus speed in the city as of 2014 is 17-18 kilometres per hour. Over the next five years it is expected to come down to 12 km per hour, whereas the maximum allowable operating speed of the vehicles shall be 80 km ph. with a maximum design speed of 90 km ph.

The Chennai Metro Rail project is expected to reduce the commuting time by 75 percent from one end of the city to another. Comparatively the registered vehicular population has increased more than two folds during the year 2011 to 2015.

The association between the type of transport, pollution and Health variables is brought out by applying correlation techniques and the result is presented in Table No: 2 from the analysis of the correlation coefficient value of transport, pollution and health variables, the following associations were identified. The transport variables like type of vehicles, travel Daily base, Purpose of travel. The type of vehicles rate in positively associated with the variable. Air pollution affects health and air pollution Diseases have a positive relationship with a transport variable. The negative associated variables namely travel daily base, purpose of travel; source of air pollution, air pollution affected and health have a relationship with transport variables. Has for as travel daily base its connected variables like source of air pollution, air pollution affected and air pollution affected in health, air pollution diseases and health have a relationship with positive correlation matrix. The negative association variables namely type of vehicles only positively correlation exists between purposes of travels variables like sources of air pollution and air pollution diseases. The negative relationship indicates that the variables like types of vehicles, travel in daily base, air pollution affected, air pollution affected health and health.

The Table 2 represents positive and negative associated variables names pollution. It may be seen from the table that among variables travel daily base and purpose of travel have a positive correlation the negative correlation like type of vehicles, air pollution affected, air pollution affected in health, air pollution diseases and health. Among the variables travels daily base, air pollution affected health, air pollution diseases and health have a significant positively association with the correlation except the above other variables shown a negative correlation.

The variables namely type of vehicles, travel daily base, air pollution affected, air pollution diseases and health. Out of these variables are positive associated only two variables like purpose of travel, source of air pollution has shown a significant associated with negative variables. The air pollution diseases are positively associated with the variable like type of vehicle, travel daily base, purpose of travel, air pollution affected, air pollution affected in health, health. The negative correlation variables like sources of air pollution. The variables namely travel daily base, air pollution affected, air pollution affected health and air pollution diseases have a positive relationship with the health all the variable have shown a negative associated with health.

T. Nagar, Anna Nagar, Kilpauk, Vallalar Nagar and Adyar the ward located in the Chennai city. This case study Two for a resident area (Adyar, Anna Nagar) and other two is Commercial area (T. Nagar, kilpauk). One for industrial area (Vallalar Nagar) This study analyses the existing types of vehicle, main sources vehicular air pollution, purposes of travels and health factor in this case study. The questioner survey 20 sampled in the Five area. Sources of vehicular Air pollution Two-wheeler, Bus, Car, auto, in the main sources of Air pollution in Adyar, Kilpauk, Anna Nagar, Vallalar Nagar and T. Nagar. The work and college of main purpose of travel by both areas.

From observations and information from the T. Nagar and Adyar respondents, careful list of diseases affected in health factor has been prepared. Among the T. Nagar 25 precent and Adyar 30 percent, Kilpauk 25 percent, Vallalar Nagar 35 percent, Anna Nagar 20 percent responded in all health factors. Proportion of the responded in all Eye problems, cough, running nose, sneezing, 65% of T. Nagar and 55% of in Adyar, Anna Nagar of 70 percent, Kilpauk of 55 percent, Vallalar Nagar 30 percent, 5% of response skin allergy and neck pain in the both areas. 10% of response no health affected in Adyar.

Finally this analysis concluded very high ambient air quality in T.Nagar and Vallalar Nagar. T. Nagar area is very conjunction vehicular traffic and commercial area. The Vallalar Nagar is industrial area. The vehicular rate of increasing is highly correlated towards the vehicular growth. The respondent has been very high affected to eye problem, cough, running nose, sneezing in T. Nagar and Adyar area. 1, 2, 3, 4, 5, 6, 7, 8
