Urban travel time data cleaning and analysis for Automatic Number Plate Recognition

Data recorded by Automated Number Plate Recognition (ANPR) cameras can be used to determine several important traffic characteristics, such as real time travel time, travel time statistics, travel time reliability and OD matrices. In this paper ANPR data collected in Chinese city Changsha have been validated. Travel time extracted from ANPR...

A Science Mapping Review of Human and Organizational Factors in Structural Reliability

In the structural safety field, it is widely acknowledged that human error is the major contributor to structural failure. Since Human and Organizational Factors (HOFs) are critical latent conditions that can lead to human errors and further structural failures, it is essential to study into HOFs in the building industry to prevent the...

From the lab to the OB truck: Object-based broadcasting at the FA Cup in Wembley Stadium

While traditional live-broadcasting is typically comprised of a handful of well-defined workflows, these become insufficient when targeting multiple screens and interactive companion devices on the viewer side. In this case study, we describe the development of an end-to-end system enabling immersive and interactive experiences using an...

Influence of driver characteristics on emissions and fuel consumption

All drivers have individual ways of driving. Still, there are groups of drivers with more or less similar characteristics. In this research, 28 drivers from Chengdu city (P.R. China) participated in an experiment where car following behaviour was measured with GPS devices. In every measured trip there was a leading and following vehicle both...

Generation and detection of non-Gaussian phonon-added coherent states in optomechanical systems

Determining the macroscopic fundamental diagram from mixed and partial traffic data

The macroscopic fundamental diagram (MFD) is a graphical method used to characterize the traffic state in a road network and to monitor and evaluate the effect of traffic management. For the determination of an MFD, both traffic volumes and traffic densities are needed. This study introduces a methodology to determine an MFD using combined...

Urban travel time reliability at different traffic conditions

The decision making of travelers for route choice and departure time choice depends on the expected travel time and its reliability. A common understanding of reliability is that it is related to several statistical properties of the travel time distribution, especially to the standard deviation of the travel time and also to the skewness....

Travel Time Reliability for Urban Networks: Modelling and Empirics

The importance of travel time reliability in traffic management, control, and network design has received a lot of attention in the past decade. In this paper, a network travel time distribution model based on the Johnson curve system is proposed. The model is applied to field travel time data collected by Automated Number Plate Recognition ...

Influence of driver characteristics on emissions and fuel consumption

Fuel consumption and atmospheric pollution emissions of vehicles depend on driving conditions, the characteristics of the driver and the car. The influence of driving style on the environmental aspects of a car journey has been investigated. Driver characteristics were determined by a Driver Behaviour Questionnaire and observed acceleration...
