Speed ranges of Level of Service (LOS) categories of urban streets are not well defined for highly
heterogeneous traffic flow condition on urban streets in Indian context. In this respect, a study was carried
out in the city of Mumbai, India and the result was tested on two major corridors in Kolkata City.
Average travel speed on street segments is used as the measure of effectiveness, which in this case has
been derived from second by second speed data collected using Global Positioning System (GPS)
receiver fitted on mobile vehicles. Hierarchical Agglomerative Clustering (HAC) is applied on average
travel speeds to define the speed ranges of urban street and LOS categories. Applying this methodology it
is found that urban street speed-ranges of LOS categories valid in Indian context are different from that
values specified in HCM (2000). The application of this procedure is that in a simple manner with the
application of GPS it can be applied in the evaluation of level of service of urban streets in different
