This research offers assessment of the urban streets in Lattakia city center. These arterials
form main traffic links between major regions. Therefore, Traffic improvement on these
streets will have great effect on improving level of service (LOS),
increasing speeds,
decreasing delay time, decreasing the emissions and traffic accidents.
This research was done on six streets surrounding Lattakia city center for defining LOS.
Floating vehicle was used in this study. Many trips were executed during free flow and
peak periods for measuring free flow speed, Travel time and average speed.
Every street was divided into many sections. This study uses field method and computation
method adopted by Highway Capacity Manual (HCM2000) for defining LOS on streets
and comparing results.
This study showed low values of LOS for most sections and it indicated deference between
field method and computation method. Also, it expressed the necessary to take suitable
procedures to increase LOS on these streets.
