Abstract:

Simuladores de tráfego são ferramentas importantes para planejamento e operação do tráfego, pois permitem avaliar cenários de maneira segura e com baixo custo. Porém, a configuração original desses programas é ajustada para replicar as condições do tráfego observado no país de origem do simulador. Em rodovias, o modelo de desempenho de caminhões tem grande influência no comportamento da corrente de tráfego. No Vissim, todavia, esse modelo simula veículos com melhor desempenho, se comparados aos caminhões brasileiros. Apresenta-se neste trabalho a calibração das funções de aceleração para camin

Abstract:

The growth of serious injuries and fatalities resulting from traffic accidents at intersections is one of the main problems in urban areas. Signal control was proposed as an alternative intersection design on rural roads. There were many reasons behind this, the most outstanding of which was the traffic signals can be used as a cost effective tools for traffic management in urban areas. The LHOVRA technique was intended to improve safety and reduce lost time at signalized intersection along high speed roads. The LHOVRA technique is an isolated traffic control strategy in Sweden which is formed

Abstract:

Bicycles are one of the most efficient way to travel within short-distance trips due to its relatively low maintenance and operation costs (Gao, Liu, & Feng, 2012). Besides to their efficiency, bicycles provide more flexibility for their parking and its ease of use. With the increasing transportation demand in major cities, transportation authorities will encourage to use the bicycle more. However, accommodating bicycles would require physical road geometry modifications such as introducing dedicated bicycle-lanes. Cycling appears to be a sustainable form of transportation across virous co

Microscopic traffic simulation software have gained significant popularity and are widely used both in industry and research mainly because of the ability of these tools to reflect the dynamic nature of the transportation system in a stochastic fashion. To better utilize these software, it is necessary to understand the underlying logic and differences between them. A Car-following model is the core of every microscopic traffic simulation software. In the context of this research, the thesis develops procedures for calibrating the steady-state car-following models in a number of well known m

Variable speed limits (VSL) are dynamic traffic management systems designed to increase the efficiency and safety of highways.

Specifically, driver compliance to advisory VSL systems is quantified based on a driving-simulation experiment and introduced into a broader microscopic behavior model. Statistical analysis indicates that VSL compliance can be predicted based upon several VSL design parameters. The

Alternatively, by identifying underutilized links, for example, in the form of parallel routes, the already existing infrastructure can often be used more efficient.

Abstract:

The purpose of this thesis was to perform microsimulation analyses on intersections near Highway-Railroad Grade Crossings (HRGCs) to determine if controlling mean train speed and train speed variability would improve safety and reduce delays. This research focused on three specific areas. First, average vehicle delay was examined, and this delay was compared for seven specific train speed distributions, including existing conditions. Furthermore, each distribution was associated with train detectors that were placed at the distance the fastest train could travel during the given warning tim

Abstract:

All computer simulation models require some form of initialization before their outputs can be considered meaningful. Simulation models are typically initialized in a particular, often "empty" state and therefore must be "warmed-up" for an unknown amount of simulation time before reaching a "quasi-steady-state" representative of the systems' performance. The portion of the output series that is influenced by the arbitrary initialization is referred to as the initial transient and is a widely recognized problem in simulation analysis. Although several methods exist for removing the initial tr

La congestión vehicular es un problema considerable en Lima en los últimos años, esto se debe al crecimiento demográfico continuo, el centralismo financiero, la escasa planificación urbanística y el crecimiento sostenido del parque automotor. La realización del presente proyecto se centra en una intersección ubicada en el distrito de Jesús María, y para ello, al tratarse del análisis de los desplazamientos de todos los modos de transporte, se utilizará un modelo microscópico.

Los problemas de congestión vehicular y la falta de inclusión de los peatones en el sistema de tránsito son alarmantes. Para solucionar la problemática se ha venido analizando la situación de manera tradicional mediante modelos determinísticos que solo se enfocan en los vehículos. En la actualidad, se han desarrollado nuevos modelos como el de micro simulación que busca analizar todos los aspectos que implican la gestión del tránsito.

This research develops a computer simulation method for federating an Arena© port operations model and a VISSIM© roadway network operations model. The development of this method is inspired by the High Level Architecture (HLA) standard for federating simulations, and incorporates several elements of the HLA principles into its design. The federated simulation model is then tested using a time-lag experiment to demonstrate the presence of feedback loops between federated model components wherein changes to input parameters of one model during runtime can be shown to affect the operational per

Abstract:

Advanced Driver Assistance Systems (ADAS) offer the possibility of helping drivers to fulfill their driving tasks. Automated vehicles are capable of communicating with surrounding vehicles (V2V) and infrastructure (V2I) in order to collect and provide essential information about driving environment. Studies have proved that automated vehicles have a potential to decrease traffic congestion on road networks by reducing the time headway, enhancing the traffic capacity and improving the safety margins in car following. Furthermore, vehicle movement and drivers behavior of conventional vehicles w

Abstract:

This thesis seeks to estimate CO2 emissions on a portion of the U.S. 101 highway in San Luis Obispo County before and after construction of a truck only lane on the Cuesta Grade. Towards that aim, the microsimulation software, VISSIM, was used in conjunction with the Environmental Protection Agency’s emissions model, MOVES. The microsimulation model was calibrated and validated against historical and present traffic volumes obtained from Caltrans with good results using several validation measures. It was found that CO2 emissions did decrease between 1998 and 2012 (pre and post lane addition),

Por otro lado, en un inicio se usaron modelos determinísticos pues se creía que estos llevarían a una única solución viable; sin embargo, en la actualidad se conoce que los modelos estocásticos presentan soluciones más veraces con

Abstract:

Traffic safety is one of the most essential aspects of transportation engineering. However, most crash prediction models are statistically-based prediction methods, which require significant efforts in crash data collection and may not be applied in particular traffic environments due to the limitation of data sources. Traditional traffic conflict studies are mostly field-based studies depending on manual counting, which is also labor-intensive and oftentimes inaccurate. Nowadays, simulation tools are widely utilized in traffic conflict studies. However, there is not a surrogate indicator that
