In the mean time the performance of transit could be increased through identifying the barriares and effective elemnts of transit cargo attracting.It is the the purpose of the present paper to identify and select the most effective indicies in transit industry at ports. To do this, all of the possible factors and bottlenecks in a transit process are uncovered through library research, interviews and Delfi technics. Then they are categorised based on the three models of fish bone model, type of indices as well as quantity and qualities of indecies. In order to find out wheather each associated factors has an affect on the transit process or not, the binominal test is applied. To do this, a five point likert scale quationer form consist of 27 items was distributed among 16 transit experts. Analysis is done through SPSS softwere. The result indicates that factors such as advertising in shipping line attracting, 24 hourse a day, seven days a week services and having cargo-handling geras with high capacity are observed as non effective factors in transit industry while economic/ prices stability and effective multy modal connectivity at ports (road, railway , aviation..) are considered as effective factors in transit industry. Finnaly, along with the investigation of transit issues at north port of Iran, some identified indices such as port time, vessel throughput and berth throughput are scrutnized at Anzali port as a case study.
