Proton and alpha particle collisional transport coefficients (isotropization,relative deceleration frequencies and heating rates) at 1 AU are quantifiedusing the WIND/SWE data. In agreement with previous studies the ion-ion Coulombcollisions are generally important for slow solar wind streams and tend toreduce the temperature anisotropies, the differential streaming and thedifferences between proton and alpha particle temperatures. In slow solar windstreams the Coulomb collisions between protons and alpha particles areimportant for the overall proton energetics as well as for the relativedeceleration between the two species. It is also shown that ion temperatureanisotropies and differential streaming need to be generally taken into accountfor evaluation of the collisional transport coefficients.
