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

商业的运输和电信受到电信技术进步的影响。本研究思考电信发展与商业运输需求之间的关系与互动。交通和电信有城市内部和城市之间的区别。本文对传播内容和传播媒介的选择进行了调查。利用调查数据建立了传播媒介选择模型。然后，我们思考了通信技术的进步对交通需求的影响，并以仙台市的企业为对象，对城市间商务通信的交通内容和通信媒体的选择进行了调查。分析了交通运输与电信之间的相互作用。然后，对于城市内的商业通信，在日本各地都有分支机构的电气设备制造商的交通和电信媒体的选择的内容的调查。计算了人均面对面通信量和通信量，建立了通信媒介选择模型，需要对每种通信媒介的属性进行设置。运用层次分析法对各传播媒介的属性及其对各业务活动的必要性进行了测度。收集替代介质的订单数据。将联合logit模型应用于传播媒介选择模型。人们发现，有一个公平的可能性，以改变面对面的通信电信。

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.
