Infrastructure

The structure of road networks plays a pivotal role in shaping transportation dynamics. It also provides insights into how drivers experience city streets and helps uncover each urban environment's unique characteristics and challenges. Consequently, characterizing cities based on their road network patterns can facilitate the identification of similarities and differences, informing collaborative traffic management strategies, particularly at a regional scale. While previous studies have investigated global network patterns for cities, they have often overlooked detailed characterizations...

Performance pricing for parking is similar to congestion pricing for roads: both use prices to "clear the market" and prevent the overuse of scarce infrastructure. For researchers, SFpark provided a real-world test of performance pricing. Would raising the price for parking nudge occupancy down and vacancy up in one of America's densest and most congested cities? Many cities keep valuable street spaces free or under-priced, and as a result they fill up quickly, leaving shortages at busy times. Most cities prefer to keep roads and parking free, even though cities that have experimented with...

Multi-vehicle applications rely on the dynamic allocation of resources, and must exhibit robustness to failures or to service degradation in general. We present a model for such applications, called the service network model. The entities of this model are services and service providers. Services are defined by standard names and interfaces, and are described by attributes. Service providers export services with certain quality of service guarantees. They may also need to import services from other providers. An application is modeled as a directed graph, where nodes represent service...

Catastrophic natural disasters like earthquakes can cause infrastructure damage. Emergency response agencies need to assess damage precisely while repeating this process for infrastructures with different shapes and types. The authors aim for an autonomous Unmanned Aerial Vehicle (UAV) platform equipped with a 3D LiDAR sensor to comprehensively and accurately scan the infrastructure and map it with a predefined resolution r. During the inspection, the UAV needs to decide on the Next Best View (NBV) position to maximize the gathered information while avoiding collision at high speed. The...
