|Brief Description of Research Project||Therefore, the objective of this study is to develop a framework to prioritize ITS technology needs for physical transportation systems, considering the requirements specific to an urban city being smart. The proposed prioritization framework at a city level consists of three main tasks as follows: Task-1. Development of an approach to evaluate the different requirements of individual cities; Task-2. Development of a reference table to quantify the benefits of ITS technologies; Task-3. Prioritization of ITS techniques and evaluation of the prioritization framework through a case study. Also, a final report as the last task (Task-4) will be delivered, following the previous three tasks. More details for each task are presented below.
One of the most common issues observed in the Baltimore City bus transit system is the crumbling of bus pads, where the buses stop to pick up riders. Bus pads are highly durable areas of the city roadways at bus stops, typically made of concrete, which is used to address the issue of asphalt distortion at bus stops. This issue is more problematic at high-volume stops where idling buses further heat the roadway surface, as well as near-side stops in mixed-traffic lanes where trucks may be adding to wear and tear. Cracks and damage in concrete pavement occur as a result of shrinkage, settlement, uplift, and excessive weight on the slab. Therefore, there is a continuous need to investigate the cause of the cracking of bus pads and develop a more sustainable design and monitoring approach so that bus pads are not replaced as often, reducing costs and disruptions to service.
The sustainability of pavement materials is a major issue that started to be strongly felt in view of a global perspective of environmental protection. Wasted materials often may find a new lifecycle if well re-engineered, even in structural applications. In this field short steel fibers obtained from used tires at the end of their life may find promising applications within a concrete matrix. In this study the mechanical properties of Recycled Steel Fiber-Reinforced Concrete (RSFRC) in terms of workability, compressive and tensile strength, toughness and shear behavior will be analyzed and compared with other types of fiber reinforced concrete including Glass Fiber Reinforced Concrete (GFRC) and Steel Fiber Reinforced Concrete (SFRC), as well as non-fiber reinforced concrete.
