Measures of effectiveness (MOE) of a road system is one of the critical issues faced in highway planning and management. Level of service (LOS) is a qualitative measures describing the operational condition of a transportation facility. The LOS concept devised by US-HCM is unfit for direct implementation in Indian heterogeneous mixed traffic condition. This is mainly due to the heterogeneous traffic conditions and vastly unique driver behavior found on Indian highways. Thus a well-defined LOS criterion for heterogeneous traffic condition is utmost necessary. The vehicles prevailing under heterogeneous traffic vary widely in static and dynamic nature. An attempt has been made in this study to define the LOS criteria per lane basis on multilane highways in terms of traffic density, considering the distribution of traffic across the lanes. LOS being a classification problem has been obtained by Clustering technique in the present study. K-means clustering methods have been employed to classify LOS in six categories.

In this paper an assessment of the current level of road safety in Kolkata is made utilizing data obtained from secondary sources. The road safety level in Kolkata is assessed considering four parameters, namely, accident severity index, accident fatality rate, accident fatality risk and accident risk. The study is primarily confined to the accident characteristics of passenger vehicles in Kolkata. Models for the projection of future accidents in terms of total accidents and fatality and injury types of accidents have also been developed. These models can be used as tools to measure the effectiveness of future safety improvements implemented in the city.
