This paper analyzes the performance of a vehicular ad hoc network (VANET)\nmodeled as a Cox process, where the spatial layout of the roads is modeled by a\nPoisson line process (PLP) and the locations of nodes on each line are modeled\nas a 1D Poisson point process (PPP). For this setup, we characterize the\nsuccess probability of a typical link and the area spectral efficiency (ASE) of\nthe network assuming slotted ALOHA as the channel access scheme. We then\nconcretely establish that the success probability of a typical link in a VANET\nmodeled using a Cox process converges to that of a 1D and 2D PPP for some\nextreme values of the line and node densities. We also study the trends in\nsuccess probability as a function of the system parameters and show that the\noptimum transmission probability that maximizes the ASE for this Cox process\nmodel differs significantly from those of the relatively-simpler 1D and 2D PPP\nmodels used commonly in the literature to model vehicular networks.\n
