SETENGE and Beta 2 Engenharia Reduced Traffic with New Roundabout in Ribeirão Preto, Brazil - 1

CASE STUDY Project Summary Organization SETENGE / Beta 2 Engenharia Solution: Roads Location Ribeirão Preto, São Paulo, Brazil Project Objectives • Develop the ideal geometric design of an interchange that connects five roadways that do not interweave, reducing accidents and traffic congestion. • Create a roadway system that fulfills the vehicle demands and traffic capacity of Waldo Adalberto da Silveira over the next 30 years, currently accommodating approximately 80,000 vehicles per day. Products Used: Descartes, OpenRoads, RM Bridge Fast Facts • The government of São Paulo retained SETENGE and Beta 2 to optimize, design, and construct an interchange that incorporates traffic from five highways and four cities. • Beta 2 used OpenRoads to determine an optimal geometric design through optioneering and an efficient engineering design workflow. • Collaboration between the structure and geometry teams was enabled by OpenRoads and RM Bridge helping the team analyse various scenario’s and deliver the optimal result. ROI • Use of Bentley software and modern construction techniques enabled the project to be completed four months ahead of schedule. • Generating high-quality deliverables with Bentley technology swiftly facilitated all other aspects of the project, reducing costs and time. • The new interchange complex decreased traffic, collisions, and energy consumption for 1.5 million people. SETENGE and Beta 2 Engenharia Reduced Traffic with New Roundabout in Ribeirão Preto, Brazil OpenRoads and RM Bridge Pinpoint Ideal Design Solution with Generative Design Workflows Revamping a Congested Interchange The city of Ribeirão Preto, located in the state of São Paulo in Brazil, is an epicenter of agribusiness and a hub of commerce, generating an influx of people to the city, boosting the population and increasing traffic congestion. The Waldo Adalberto da Silveira, the major access interchange to Ribeirão Preto, is a roundabout constructed in 1972. With a daily traffic volume of around 80,000 vehicles joining it from five highways, many collisions occurred on the access interchange due to inefficient transit interconnection. The government of São Paulo initiated a BRL 120 million project to design a roadway network able to reduce congestion and car accidents as well as meet predicted traffic demands over the next 30 years. The government requested that Arteris, a private company licensed to manage the highway, include the project as part of its ongoing administration in the locality. To improve the interchange, SETENGE and Beta 2 Engenharia Arteris retained to completely remodel the highway system. Founded in 1999, Beta 2 Engenharia is a privately owned company that specializes in the development of structural design and analysis projects, concentrating on airports, bridges, and the oil and gas industry. SETENGE is a company that offers road topography and all types of geometric projects, focusing on highways, railways, and urban roads across Brazil. Both companies collaborated due to their expertise in this kind of project. SETENGE and Beta 2 were tasked with creating a design able to handle the traffic capacity approaching from five highways, eliminate interweaving traffic, and renovate the drainage, lighting, and sewage in the area. The construction of the new roundabout needed to be scheduled and sequenced in a manner that ensured the old roundabout remained operational, and, as the new complex was required to be located in the same area, with the least amount of expropriation of land. Analyzing Models with OpenRoads SETENGE used Descartes to combine aerial photographs with drawings and integrated everything within a single image in order to decipher the optimal geometry of the complex. Then, SETENGE conducted a topographic study of the area where the roundabout was located and used OpenRoads to create a digital terrain model, before mapping out and studying all possible scenarios. The horizontal alignment of the highway connections were examined in relation to the digital terrain model, before engineers analyzed the vertical alignment and application of superelevation using roadway design functionality in the application. Population Boom Makes Interchange Obsolete The population of Ribeirão Preto grew exponentially in recent years as the city is a hub for national agribusiness, specifically sugar cane, and a regional economic center, with Brazilians from other cities coming to Ribeirão Preto for health services and education. The population boom led to an increase of vehicles on the roadways. The main roundabout entering Ribeirão Preto was 420 meters and merged vehicles from five highways and four cities, which saw about 8,000 vehicles per hour during peak periods. This high traffic volume led to inappropriate weavings of cars and many vehicular collisions. Consequently, the government recommended a total renovation of the roundabout. A combination of aerial photographs and drawings were combined in Descartes to create th

RM Bridge uses a generative design workflow for the modeling steps and the analysis stages, so when one change is entered into the software, all of the correlating data is updated to reflect that change. Through this application, the project team calibrated the models with real-world information from the construction team, such as concrete strength, and modifications were handled quickly and efficiently, saving significant time. Additionally, RM Bridge generated the calculation log, eliminating time spent issuing project documents. OpenRoads and RM Bridge allows project companies in the...
