DESCRIPTION:I will introduce a persistent random walk model wi
 th finite velocity and self-reinforcing directiona
 lity\, which explains how exponentially distribute
 d runs can lead to superdiffusion observed in acti
 ve intracellular transport. We derive the governin
 g hyperbolic partial differential equation for the
  probability density function (PDF) of particle po
 sitions. This PDF exhibits a bimodal density (aggr
 egation phenomena) in the superdiffusive regime. I
  also present the exact solutions for the first an
 d second moments and the criteria for the transiti
 on to superdiffusion. Furthermore\, this model is 
 extended to incorporate rests which can lead to bo
 th superdiffusive or subdiffusive motion.
