One of the most important indications of development is that people can travel with safe, comfortable, fast and economical means

of transportation. For this reason, there is a continuing transportation investment in our country. Transportation investment is

projected and implemented based on requirements of the next 20 years. Hourly, daily, monthly and annual variations in expected

traffic flow are important in the determination of road standards. There are some accepted changes in traffic flow; for example,

traffic is more dense during daylight than it is at night; during holidays traffic is more dense out of cities than it is within cities;

but on weekdays it is more crowded within city than it is out of cities; and there are more vehicles on roads in summer months

than in winter months. In this study, 1573 traffic accidents that occurred in Eskisehir in 2009 are reviewed according to their time

of occurrence, and the relationship between number of accidents and occurrence times is examined. Finally, in order to prevent

accidents, possible precautions are stated considering that relationship. Additionally, it has been analyzed with chi-square test in

SPSS program that whether the days have a significant effect on the accident hours.
