Road transportation is one of the main source of carbon dioxide emissions, and it is imperative to estimate the carbon dioxide contribution of road transportation precisely, so that carbon dioxide emission-reduction measures can be designed and implemented appropriately. Microscopic emission models and GPS trajectories are widely used in estimating carbon dioxide emissions. Microscopic emission models...
With the rapid development of urbanization in China, the governments usually face the problem of traffic congestion, mainly due to the rapid increase in traffic demand. Group disparity between commuting mode choice and origin destination space distribution has enabled us to explore the cause of these differences and basic causes of traffic congestion. In recent years, commuting mode and behavior-based...
In last two years, the rapid development of Internet based ride-sharing has brought great changes to travel pattern of residents. However, few studies has been made to find out the unique travel patterns of Internet based ride-sharing. In this paper, License plate data at the Beijing Capital International Airport area are used to study the travel patterns of taxis and private cars. By comparing the...
In order to explore driver's mental workload under different traffic situations, the field experiment aimed at giving quantitative assessments of driver's mental workload within different maneuvers by physiological indicators, such as ECG and EDA. Moreover, the driving safety assessments in different mental workload were analyzed. Firstly, the HRV was extracted from the ECG signal de-noised and filtered...
Due to its importance, lots of investigations had been carried out in the last four decades to study the relationship between phase duration and vehicle departure amount. In this paper, we aim to build appropriate distribution models for start-up lost time and effective departure flow rate, by considering their relations with the frequently mentioned departure headway distributions. The motivation...
With rapid development of transportation system, traffic information collection, which provides accurate and reliable traffic data, receives more and more attentions. However, under practical conditions, most roads and freeways are equipped with limited amount of loop detectors. Thus, researchers are delving into traffic information reconstruction by utilizing limited information. In this paper, we...
This paper mainly focuses on different influences on traffic flow in large traffic flow conditions, caused by different distances between off-ramp and on-ramp on expressways. In addition, a signal control strategy on side road is proposed and discussed. Our research is based on traffic simulation software (VISSIM). In this research, the characteristics to describe traffic features include average...
In order to reduce the congestion near bus stops, optimal design of bus stops through redesigning berth assignment was proposed in previous research. Three principles were raised to guide the berth assignment planning, however which principle played a more significant role was not discussed before. In this paper how to plan berth assignment for an actual multi-berth bus stop and which principle is...
Testing and improving commercial traffic software remain as important research topics in the last three decades. Many previous approaches emphasized the driving behaviors of uninterrupted flows (e.g. car-following and lane-changing features) but paid less attentions to the driving behaviors of interrupted flows. In the paper, the distribution of reproduced departure headways at signalized intersection...
With the rapid development of intelligent building, the requirement of automatic number identification of civilian instrumentations is increasingly urgent. This article uses iterative global threshold to binarize the images and then adopts projection method to locate the target regions and divide the numbers. The back-propagation neural network is used to recognize the numbers. The result indicates...
Nowadays, Wireless Monitoring for home security is among the cutting-edge researches in the field of International Intelligent Building. To implement real-time surveillance of the home security, the intelligent remote monitoring system was developed for home security based on ZigBee technology and GSM / GPRS network. The system can send abnormal images and warning messages through MMS and SMS, receive...
