The Influence of The Progression of Telecommunication Technology on The Transportation Demand

电信技术的进步影响着商业运输和电信。本研究探讨电信发展与企业运输需求之间的关系与互动。城际和城内的交通和通信被区分开来。我们对运输的内容和通信媒介的选择进行了调查。利用本次调查的数据，建立了传播媒介选择模型。然后，我们考虑了电信技术的进步对交通需求的影响。对城际业务通信的运输内容和通信媒体选择的调查，使仙台市的公司感到愤怒。分析了交通运输与电信的相互作用。然后，对于城市内的商业通信，在一家在日本各地都有分支机构的电气设备制造商调查运输内容和电信媒体的选择。计算了人均面对面交流和通信的数量。为建立传播媒介选择模型，有必要对每种传播媒介的属性进行设置。采用层次分析法对各传播媒介的属性和各业务活动的必要性进行了度量。收集了替代媒体的订单数据。将联合logit模型应用于传播媒介选择模型。调查发现，将面对面的通信方式改为通信方式的可能性相当大。

The transportation and telecommunication of business are affected by the progression of telecommunication technology. This research thought about relation and interaction between the progression of telecommunication and the transportation demand of business. The transportation and telecommunication were distinguished between intra-city and inter-city. We made an investigation of the contents of transpotation and the choice of telecommunication media. The communication media choice model was made by using the data of this investigation. Then, we thought about the influence of the progression of telecommunication technology on the transportation demand.The investigation of the contents of transportation and the choice of telecommunication media for inter-city business communication was mad at the companies in Sendai city. The interaction between toransportation and telecommunication was analyzed. Then, for intra-city business communication, the investigation of the contents of transportation and the choice of telecommunication media at an electrical equipment manufacturer, which has branches in all parts of Japan. The quantity per person of face-to face communication and telecommunication were calculated.It is necessary to set up the attribute of each communication medea for the making of the communication media choise model. The attribute of each communicatin media and the necessity of the attribute for each business activity were measured by using Analytic Hierarchy Process method. The order data of the alternative media was gathered. The conjoint logit model was applied to the communication media choice model. It was found that there is a fair possiblity to change face-to-face communication for telecommunication.
