In this paper, we have evaluated performance of various routing protocols for Vehicular Ad Hoc Network (VANET) in different traffic patterns with real vehicular traces. The vehicular movements are based on intelligent driver model with road intersection. Our objectives is to provide a comparative analysis among various ad hoc routing protocols based on packet delivery ratio. Routing protocols are LAR1, AODV and DSR protocols. The traffic patterns categorize as sparse, moderate and dense based on the number of nodes. The results show that LAR1 protocol outperform others. The maximum packet delivery ratio obtained is 99.52% in the sparsely populated network. We have used Glomosim 2.03 and VANETMobiSim simulator for our analysis.
