This book was released on 2021 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid growth in population and related demand for travel during the past few decades has had a catalytic effect on traffic congestion, air quality, and safety in many urban areas. Transportation managers and planners have planned for new facilities to cater to the needs of users of alternative modes of transportation (e.g., public transportation, walking, and bicycling) over the next decade. However, there are no widely accepted methods, nor there is enough evidence to justify whether such plans are instrumental in improving mobility of the transportation system. Therefore, this project researches the operational performance of urban roads with heterogeneous traffic conditions to improve the mobility and reliability of people and goods. A 4-mile stretch of the Blue Line light rail transit (LRT) extension, which connects Old Concord Rd and the University of North Carolina at Charlotte's main campus on N Tryon St in Charlotte, North Carolina, was considered for travel time reliability analysis. The influence of crosswalks, sidewalks, trails, greenways, on-street bicycle lanes, bus/LRT routes and stops/stations, and street network characteristics on travel time reliability were comprehensively considered from a multimodal perspective. Likewise, a 2.5-mile-long section of the Blue Line LRT extension, which connects University City Blvd and Mallard Creek Church Rd on N Tryon St in Charlotte, North Carolina, was considered for simulation-based operational analysis. Vissim traffic simulation software was used to compute and compare delay, queue length, and maximum queue length at nine intersections to evaluate the influence of vehicles, LRT, pedestrians, and bicyclists, individually and/or combined. The statistical significance of variations in travel time reliability were particularly less in the case of links on N Tryon St with the Blue Line LRT extension. However, a decrease in travel time reliability on some links was observed on the parallel route (I85) and cross-streets. While a decrease in vehicle delay on northbound and southbound approaches of N Tryon St was observed in most cases after the LRT is in operation, the cross-streets of N Tryon St incurred a relatively higher increase in delay after the LRT is in operation. The current pedestrian and bicycling activity levels seemed insignificant to have an influence on vehicle delay at intersections. The methodological approaches from this research can be used to assess the performance of a transportation facility and identify remedial solutions from a multimodal perspective.

Download or read book Modular Agent Based Modeling of an Urban Road Network Including Its Management written by Benjamin A. Cohen and published by . This book was released on 2018 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this PhD research was to explore how the complex interdependencies of a dense urban environment can be simulated through a hybrid multi-layered model, integrating agents at different resolutions. The model incorporated: (1) the graph model of an existing road network within Philadelphia, recognizing the engineering and operational characteristics of various road segments within this network; (2) vehicles and drivers as mesoscopic agents, where the vehicle types, counts and behaviors were calibrated by actual data; (3) a time and use based deterioration model and repair techniques for different elements of the road network; and, (4) an owner agent making various asset management decisions for the road network leading to four distinct scenarios. The mesoscopic traffic simulator therefore simulated feedback mechanisms linking the drivers' decisions and behaviors to the roadway steward's decisions, revealing the short-term consequences of management policies. This provided a realistic understanding of the "user costs," corresponding to different decisions on maintenance and replacement scheduling. The model proved to be a low cost, modular, sociotechnical, cloud-based model of a surface transportation urban infrastructure asset management simulator. The main computational engine selected for the model was an open-source mesoscopic traffic simulator, SUMO, which can represent driver agents, routing algorithms, and traffic control systems for a road network. This traffic model was defined and calibrated with data and reports from the local municipal planning organization. The deterioration of each roadway segment was modeled as a function of time and the simulated traffic's vehicular loads. The roadways' speed limit was a function of the deterioration and as a result, over time, the roadways became less favorable to the vehicles trying to optimize their daily path. At the beginning of each year the owner-agents assess the current deterioration levels and develop a plan and schedule either maintenance or replacement activities in order to meet specific condition objectives while also satisfying real-world constraints. The long-term planning was accomplished through the use of linear programming, while the short-term yearly schedule was achieved through a custom prioritized scheduling algorithm. A total of four different scenarios were generated to observe and compare the effects of different management policies and approaches. These included a baseline Do-Nothing scenario, a scenario based on a reactive short-term yearly scheduling scheme, and two scenarios that incorporated both short-term and long-term approaches to planning and scheduling with different constraints. A computer program was written in the Python language and adapted to take advantage of elastic cloud computing processing power to integrate the different modular components in order to simulate the daily activities within the network during a five-year period. The data from the simulations were then processed, analyzed, and visualized utilizing a combination of Python and Excel. The results for all the scenarios were compared with regards to the roadways' overall and yearly condition ratings as well as user-costs. Given the relatively short run-time of the simulation in comparison to the life-span of the assets, the short-term reactive scenario performed better than the two long-term based scenarios in the overall condition of the network. However, for longer-periods of simulation we should expect changes in the resulting operational performance and cost for different scenarios. The study was successful in demonstrating the potential of integrative modeling of complex sociotechnical infrastructures, and the computational requirements for simulating entire urban regions with interdependent infrastructures.

Download or read book Fundamentals of Traffic Simulation written by Jaume Barceló and published by Springer Science & Business Media. This book was released on 2011-01-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing power of computer technologies, the evolution of software en- neering and the advent of the intelligent transport systems has prompted traf c simulation to become one of the most used approaches for traf c analysis in s- port of the design and evaluation of traf c systems. The ability of traf c simulation to emulate the time variability of traf c phenomena makes it a unique tool for capturing the complexity of traf c systems. In recent years, traf c simulation – and namely microscopic traf c simulation – has moved from the academic to the professional world. A wide variety of traf- c simulation software is currently available on the market and it is utilized by thousands of users, consultants, researchers and public agencies. Microscopic traf c simulation based on the emulation of traf c ows from the dynamics of individual vehicles is becoming one the most attractive approaches. However, traf c simulation still lacks a uni ed treatment. Dozens of papers on theory and applications are published in scienti c journals every year. A search of simulation-related papers and workshops through the proceedings of the last annual TRB meetings would support this assertion, as would a review of the minutes from speci cally dedicated meetings such as the International Symposiums on Traf c Simulation (Yokohama, 2002; Lausanne, 2006; Brisbane, 2008) or the International Workshops on Traf c Modeling and Simulation (Tucson, 2001; Barcelona, 2003; Sedona, 2005; Graz 2008). Yet, the only comprehensive treatment of the subject to be found so far is in the user’s manuals of various software products.
