The Domestic LPI database can be used to unpack these aggregate results and
obtain more details on their drivers. One particularly important example is the
identification of major sources of delay, which are a key determinant of timeliness.
The data cover delays due to the following causes: compulsory warehousing and
trans loading, pre-shipment inspection, maritime transshipment, criminal activities
(such as theft), and solicitation of informal payments in association with logistics
activities. For each source of delay, the LPI database reports the percentage of survey
respondents indicating that major delays are “nearly always” or “often” experienced for
that reason
