高速公路收费站收费业务质量评价体系研究

收费业务是高速公路运营中最为重要的业务,其业务质量是表征运营质量的关键。目前,国内针对收费业务质量开展评价的研究较少,也尚未形成一套行业认可的评价体系。采用AHP和模糊评价相结合的方法对收费站收费业务质量评价体系的建立及评价方法进行研究,确定对应的层次模型及指标权重。采用该模型对四川省3个具有代表性的收费站进行评价,得出的结果与实际情况相符。     

A zone design methodology for national freight origin–destination data and transportation modeling

The zone system used for freight data collection and the geographic resolution of published data has a significant impact on analysis and planning. The majority of existing freight model zones are created in an ad hoc way. In this paper, a new model-based design method is introduced to develop freight zones for the continental USA. It focuses on two methodology issues: (1) the criteria that represent the desired properties of a zone system and (2) the constraints that govern the shape, size, and continuity of zones. The method is applied to the continental USA by optimizing an interzonal travel distance weighted by freight flows using county-level freight data. Several optimal national-level freight zone systems with different numbers of zones are developed. The results indicate that a 300-zone system provides a balance between the number of zones and optimization measures where the currently available public freight data are provided with approximately 100 zones.     

全新一代无人收费机器人

Behavioral responses to pre-planned road capacity reduction based on smartphone GPS trajectory data: A functional data analysis approach

Abstract

Pre-planned events such as constructions or special events lead to road capacity reductions and create bottlenecks in the traffic network. The traffic impact of such events goes beyond local areas, as informed drivers may detour to alternative corridors and consequently the traffic congestion may divert or propagate to other corridors. Due to the lack of real observation data, traditional traffic impact analyses are typically based on simulation models, fixed-location sensor data or survey questionnaires. In this research, we use high-resolution vehicle trajectory data collected via a smartphone app, which is capable of keeping track of individual driver’s behavior before and after road capacity reduction, to investigate travelers’ behavioral responses to pre-planned events and the contribution factors. For this purpose, a functional data analysis (FDA) approach-based clustering method is firstly proposed to cluster trajectory data and identify detour patterns, and two logistic and a least absolute shrinkage and selection operator (LASSO) regression models are used to explain drivers’ detour behavior choice for each pattern with spatial and temporal features of interest. A case study based on a lane closure event on MoPac expressway in Austin, TX is used as an example in this research. The case study demonstrates that: (1) the freeway capacity reduction triggered heterologous behavior responses, (2) driver detour behavior exhibits three major patterns and (3) each detour pattern highly depends on spatial features such as trip length, distance to freeway entrance and distance to other alternative freeways, in addition to the temporal features when the trip happens.     

浅析ETC在内蒙古高速公路的推广应用

随着收费公路在各省区内成网,ETC应运而生。在国家取消高速公路省界收费站的进程中,ETC用户的占比成为此项改革成败的关键指标。文章通过对ETC在我国及内蒙古地区的发展历程分析、解读,旨在明确取消省界站和推广ETC在逻辑上顺承和事实上依存关系,同时,探讨ETC在内蒙古的推广应用,明确指出随着云计算、大数据、边缘计算、AI的迅速普及和高效运用,未来这张网的走向应该是产业互联网。     

城市轨道交通网络换乘性能研究

针对网络换乘性能,提出了计算城市轨道交通网络换乘次数的矩阵算法。利用图论建立网络数学模型,利用可达矩阵计算了网络拓扑结构的平均换乘次数。在此基础上考虑客流量的影响,通过挖掘地铁AFC(自动售检票)数据,计算按客流量加权的平均按乘次数。定义网络换乘效率为实际按乘次数与理论换乘次数的比值,并以北京地铁为例进行计算。计算结果验证了算法的有效性。
