In this paper, M/G/C/C state dependent queueing models are proposed for modeling and analyzing vehicular traffic flows. Congestion aspects of traffic flow are represented by introducing state dependent service rates as a function of number of vehicles on each road link. Analytical models for unidirectional and multisource flows are presented. Finally, queueing models to analytically determine the optimal capacity and performance measures of the road links are incorporated into a series of software programs available from the authors.

The in vivo pattern of ocular surface epithelialization after SLET appears to be similar to in vitro epithelialization observed after CLET. The observations in this study provide a lead for performing further laboratory and clinical research in SLET.
