摘要

本文介绍了为波兰卢布林和波兹南两个城市的两个已完成的道路建设项目开发的两个交通预测模型。将两种模型的预测结果与现场数据进行了比较。在第一部分中，文章介绍了目前用于计算确定道路项目可行性的模型，包括表明道路交通预测与实际道路运营和道路项目可行性之间的关系。第二部分介绍了关于道路项目的各种国际研究的结果，以显示预测和实际交通量之间的差异，这是大多数发达国家的典型情况。然后，本文讨论了在分析的道路工程中观察到的模型输出与实际交通及其结构的差异。最后，作者就交通模型(以及由此得出的交通预测)与实际交通绩效之间的不一致性提出了结论。

Differences between the traffic model and the actual road traffic and its structure

The paper presents two models of traffic forecasting developed for two completed road construction projects in two cities of Poland: Lublin and Poznan. The predictions from both models were compared with the field data. In the first part the article presents the currently used model for computational determination of road projects’ viability, including indication of relationships between road traffic forecasts on the one hand and actual road operations and viability of road projects on the other. The second part presents results of various international studies on road projects in order to show the differences between the predicted and the actual traffic volumes, which is typical for most developed countries. Then, the article discusses the differences observed between the model outputs and the actual traffic and its structure in the analysed road projects. Finally, the authors put forward their conclusions regarding the inconsistencies between the traffic models (as well as the resulting traffic forecasts) and the actual transport performance.

期刊介绍： The quarterly journal Roads and Bridges – Drogi i Mosty is published by the Road and Bridge Research Institute since September 2012 as a bilingual English-Polish journal. From 2002 to 2012 the journal was printed under the title Drogi i Mosty. The journal mission is to promote current achievements in science and technology in the field of road and bridge engineering. The journal is intended as a forum of the exchange of innovative concepts and solutions between the researches from different countries. Original scientific and technical papers in the field of civil engineering and related engineering sciences are published. The scope of Roads and Bridges – Drogi i Mosty includes design, construction, maintenance and safe use of roads, bridges, airports and other transportation structures.
