摘要

This paper examined characteristics and travel behaviour of vessel traffic at the entrance of the Houston Ship Channel (HSC) using automatic identification system (AIS) data collected for the whole year of 2014. The paper aimed to investigate the travel behaviour of vessels in a busy inland waterway. For any further analysis such as vessel traffic delay analysis, schedule optimization, risk analysis, etc., it is important to first know the traffic characteristics and travel behaviour of vessels in the channel. The entrance of the HSC sees the following types of vessels: cargos, tankers, passenger ships, harbour tugs, towing vessels, etc. Among them, cargos and tankers dominate the flow at this section of the HSC. Travel behaviour of cargos and tankers, especially those vessels carrying dangerous goods, was analyzed at this section of the HSC, which was divided into two zones with the same length. Based on vessels' travel directions, trips were categorized into outbound (towards the Gulf of Mexico) and inbound (away from the Gulf). The annual average hourly traffic was calculated for all vessels combined, as well as for major vessel types, for both directions at each zone. Specifically, the traffic speeds of different vessel types were studied. In general, the speed at the entrance of the HSC is low, and the traffic speeds of each type of vessel (tankers, cargos, as well as tankers and cargos carrying dangerous goods) were normally distributed. Moreover, the relationship between traffic speeds and density was analyzed, and found that the traffic speeds were basically independent from the density of vessels in the waterway. This paper was a preliminary study of vessel traffic characteristics and travel behaviour analysis. The methodology involved in this paper can be applied to other inland waterways to investigate travel behaviour of vessel traffic. The results of the paper revealed some important facts about characteristics and travel behaviour of vessel traffic at the entrance of the channel, which will help better understand of vessel traffic pattern and can be used for further studies on waterway transportation.
