ABSTRACT- Aiming at 6% reduction of CO2 emission in 2010, countermeasures for the decrease of CO2 emission have been carried out in each section of Japan. Especially, the amount of CO2 emission in the transportation section increases every year, and the countermeasures are pressing needs. In this study, the potentiality of a modal shift in commuting was investigated as countermeasures in order to decrease the amount of CO2 emission in the transportation section. First of all, the commuting patterns of the car in ten cities were categorized into (1) the movement in the city (2) the movement from the city to suburbs and (3) the movement from suburbs to the city, and the relation between the commuting distance and transportation was analyzed. As this result, it was guessed that most of people using the cars in commuting moved within 20km, and it was effective to promote modal shifts to these people. By the modal shift in 15% of people who were using the car in commuting, it was estimated that CO2 emission of 2.3 million tons a year could be reduced in Japan. In addition, the modal shift (car sharing) model containing the real-time navigation system and the personal authentication system was constructed, and the possibility of reduction in CO2 emission by the introducing IT (Information Technology) was discussed.
