The paper is divided into four parts. The first part of the paper is a literature
review in the field of operational transport efficiency, which is not exhaustive.
The second part reviews potential transport efficiency measures with implications
for the environmental performance of road haulage. The third part is a case study
presenting empirical findings from structured interviews with two CEOs of pickup
and delivery hauliers in the parcel and general cargo segment. The fourth part
summarizes the transport efficiency measures in a matrix, taking into account
whether they are mainly costs or benefits for the involved actors.
