The kinetics of' car clustering in a single-l?tne laighway tr;tflic flow is described in tertns ofa Boltznaann-like kinetic equation. Efl'ect of' car acceleration LlpOI1 car cltrstering is studied byderiving the velocity distribtntion of cars. The discrete version of the kinetic eqtration is presentedto solve numerically its equation. The tiraae evoltrtions of' velocity distribtrtions are calctrlated bynumerical method. The velocity distribtrtions in a steady state are ;tlso derived ntrmercally bytaking into accotrnt deceleration. It is shoxvn thsrt the velocity distribtrtion becomes broader andbroader with increasing acceleration. It is fotrnd th?xt the clustering, acceleration and decelerationhave an important efl'ect on the velocity distribtrtion of cars.
