National Travel Survey 1984-1985

The data set comes from the first National Travel Survey (RVU) in Norway, which Statistics Norway conducted for the Institute of Transport Economics in 1984-85. The main purpose of the surveys was to gather information regarding all types of travels, both daily travels and travels connected to holidays, how much we travel, what purpose the travels have, which methods of transportations are used etc. The data lay the basis for analysis of competition between different types of transportation, for examination of the effect of public initiatives in the transport sector, and the opportunity to look at the differences between different geographical areas and sections of the population.

Data regarding the population's travel activity is important for national and local transportation planning. The results are used as the basis for development of transportation models, prognosis work, exposure calculations in road safety work and in a line of investigative work and research. National Travel Surveys are also important as backdrops for evaluation of results from surveys regarding certain means of transportation or from certain geographical areas.

The survey took place over the course of a whole year, and the selected persons were equally distributed on all days (including, weekends and public holidays) in the period of 17th of September 1984 to 15th of September 1985, which means 15 persons per day. In this way, one could examine the travel activity throughout the whole year. In the survey there are several questions related to the “registration day” (“registreringsdagen”), which usually refers to the day before the registration day.

本数据集源自挪威首次全国旅行调查（National Travel Survey，缩写RVU），该调查由挪威统计局于1984至1985年间为挪威运输经济研究所开展。本次调查的核心目标是收集各类出行相关信息，涵盖日常出行与假日出行、出行频次、出行目的以及所使用的交通方式等诸多维度。上述数据可为不同交通方式间的竞争分析、交通领域公共政策举措的效果评估，以及探究不同地理区域与不同人群间的出行差异提供支撑。

人口出行活动相关数据对国家及地方交通规划具有重要意义。其研究成果可用于交通模型开发、预测分析、道路安全领域的暴露量计算，以及一系列调查与研究工作。全国旅行调查同样可作为评估特定交通方式或特定区域专项调查结果的重要参照背景。

本次调查周期覆盖完整一年，受访对象在1984年9月17日至1985年9月15日的每日（含周末与公共假日）均均匀分布，日均受访人数为15人。通过该设计可实现对全年出行活动的系统性观测。本次调查包含多个与“登记日(registreringsdagen)”相关的问题，该术语通常指代登记行为发生的前一日。
