Children’s traffic park design in USA to promote children’s traffic safety education

Hong, Jung-Sun, 1976- 21 November 2013 (has links)
Many transportation proposals aim to enhance child traffic safety, and they suggest environmental interventions, law enforcements, and educational methods as the solutions. However, educational approach has not been focusing on practices. When we consider children’s perceptual immature, hand-on education should be more efficient than verbal education. Thus, through an examination of typical child motor vehicle-related crash types in Austin and recent interviews, this Professional Report proposes a Children’s Traffic Park as a practical educational method that delivers traffic rules and influences children’s attitudes and behaviours to traffic. / text

Reliability of photography for traffic measurement

O'Grady, James Bradley January 1973 (has links)
This thesis describes a simplified method for estimating distances directly from terrestrial photographs. It was felt that any method devised must overcome present limitations and meet three basic criteria to be practical. These criteria are: 1) that the method require no subject-visible markings, 2) that it require no special equipment or training to use, and 3) that it provides sufficient accuracy to be useful. A number of possible methods were considered, and were evaluated against these criteria. the Accuacy ( reliablity) of the methods was tested using a variety of statistical tests. The recommended method consists of first selecting a reference distance whose length is known. This reference should be in a plane parallel to and approximately the same distance from the camera as the desired distance. It was found that a vehicle dimension such as the tire track gives consistently the best results. Both the reference and the desired distances are then scaled on the photograph and a ratio is applied to drectly estimate the desired distance. Greatest reliability is achieved when the subject is directly in fromt of, or behind the camera and at a distance between 50 and 250 feet. By following thers guidelines the stated objectives can be met by using this method.

On Microscopic Traffic Models, Intersections and Fundamental Diagrams

McGregor, Geoffrey 07 May 2013 (has links)
We design an Ordinary Delay Differential Equation model for car to car interaction with switching between four distinct force terms including "free acceleration'', "follow acceleration'', "follow braking'', and aggressive driving''. We calibrate this model by recreating a real experiment on spontaneous formation of traffic jams. Once simulations of our model match those of the experiment we develop a model of both intersections using traffic lights, and intersections using roundabouts. Using our calibrated car interaction model we compare traffic light versus roundabout efficiencies in both flux and fuel consumption. We also use simulation results to extract information relevant to macroscopic traffic models. A relationship between flux and density known as The Fundamental Diagram is derived, and we discuss a technique for comparing microscopic to macroscopic models. / Graduate / 0405 / gmcgrego@uvic.ca

Using of version 2.1 aaSIDRA and version 5.1 PARAMICS in the development of traffic signal coordination on Sri-Jan road Khon Kean City, Thailand /

Prabnasak, Jaruwit. Unknown Date (has links)
Use of modern traffic signal coordination has now been proved by its performance to reduce the total delay, increase driving speed and provide the smoothness of driving significantly. To provide more possibility of success in any traffic development including traffic signal coordination, traffic analytical and modelling software packages are now the best answer. This thesis illustrates the practical using of aaSIDRA and PARAMICS in development of traffic signal coordination on Sri-Jan Road, Khon Kaen City Thailand. The fixed-time signal plan with bandwidth maximization strategy is selected for the studied corridor. Two essential steps in the development are: determination of signal plans and cycle times using Version 2.1 aaSIDRA Micro-analytical software package; and determination of coordination offsets by using Version 5.1 PARAMICS Micro-simulation software package. The PARAMICS is also using in the evaluation of actual and improved traffic condition on Sri-Jan corridor. The results show that the newly proper signal plans and offsets produces significant improvements on the traffic conditions of the Sri-Jan Road. Recommendations on the motorcycle impacts and the projection of future traffic condition have also been provided for further study. / Thesis (MTransportSysEngineering)--University of South Australia, 2006.

The use of CUBE dynasim and aaSIDRA for the analysis of a signalized intersection /

Yaldi, Gusri. Unknown Date (has links)
Transport systems can be modelled and analysed with two techniques namely analytical and simulation. Until recently, aaSIDRA was the leader in the traffic modelling and analysis software based on analytical theory at micro scale. However, it cannot be used for more than one intersection. Meanwhile, the PARAMICS, AIMSUN NG and VISSIM are micro simulation software which are widely used in modelling and analysing transport systems. Further, CUBE Dynasim is also micro simulation software. It is created by Dynalogic in France and integrated in CUBE by Citilabs, UK. However, this software is relatively new compared to PARAMICS, AIMSUN NG or VISSIM. It is able to model multi nodes and multi modals transport system. The version of software used in this research is CUBE Dynasim 1.4.9 released in 2004 aaSIDRA 2.0 version 2.0.0.205. / Thesis (MTransportSysEngineering)--University of South Australia, 2005.
