N2  - The Metropolitan Police Department has recently changed the speed limit from 40 km/hour to 50 km/hour on some arterial roads within Tokyo.  We took this opportunity to conduct to analytical research projects on the relationship between driving speed and traffic accidents.  The first one carried out is an analysis of accident outbreak conditions before and after the speed limit alterations made on several roads in 1978.  The second study was a comparative analysis of accident outbreaks on the roads where the speed limit had been altered and where it had not been altered.  It was concluded that the speed limit alteration mentioned above resulted in an increase in driving speed but did not exert an unfavorable influence on traffic accidents.<p />
