Analysis of relationship between lane widths and passenger car speed

Abstract

It has been reported that speeding driving is the main presumed cause of accidents in the system CRIMES
(Criminal Record Information Management Enterprise System) in the year 2018. The cause of accident is drivers
who choose to drive over traffic regulation speed limits which may cause accident. Therefore, it is important
to choose a speed appropriate to road type and road function. This study thus aims to explore relationships
between lane width and passenger car speed by using a case study of 39 road sections covering suburban
and rural road areas.
Regression analysis was used as a statistical tool to explore and describe those relationships. The
results are shown for both suburban and urban that were 95% significant with Adjusted R Square of 0.701
and 0.944 for suburban and rural road respectively. As a results from this research, the relationship between
lane width and passenger car speed could be used as a support tool for making decisions in road design to
correspond to surrounding area land-use.
