Urban Infrastructure

Across the world, drones are increasingly finding applications in helping metropolises and large cities manage themselves- from being a force multiplier for the police in areas of traffic gridlock management and law and order enforcements to monitoring of reservoir levels and metering air pollution and smog at various strata. More recently, drones have been used as the most low-cost and efficient mechanism to map an ancient system of sewers and underground reservoirs in the city of Rome, and helped the city fathers interlink it to the present day sewage lines.
AltBird would be keen on exploring markets in the following
  • Smart city managment issues like Law and order , traffic , Garbage and waste dumps
  • Greenfield townships
  • Large civic infrastucture projects like drains , airports , bus terminals etc.
  • reservoir management
  • Pollution assessment and monitioring
  • Information

    Infrastructures contribute to long-term economic growth and have positive impact on alleviating income inequality. Therefore, it is critical to gather solid information to develop proper plans and make good decisions. However, for large-scale infrastructures that traverse complex terrain, it is not always easy to gather solid and adequate information. Furthermore, precise, and accurate traffic study is needed in order to make a good urban traffic plan. But due to high surveying cost of real time traffic monitoring in conventional ways, simplified urban travel demand models are used. UAVs can be used as efficient tools to accurately survey and map the landscape to collect necessary information before infrastructure construction to make good plans
    Designing new infrastructure could be complex and time consuming, particularly for critical ones. UAVs are potentially useful in improving design efficiency and quality. For example, UAVs can be used in post-disaster assessment of critical infrastructures that are not easy to reach or detect after an extreme event such as earthquakes; and then provide valued information for future design. For instance, three different types of drones were deployed to examine damage of the nuclear plant failure which was fatal to human even for short exposure. Improved design can be conducted by taking into account the knowledge gained from post-disaster assessment.
    Furthermore, data from real time traffic monitoring are useful for new road and bridge designs. For instance, drones are cost effective in collecting length-based vehicle classification data, which are important information for pavement design due to differences in size and weight between long vehicles and short vehicles. Compared to conventional traffic monitoring, drones can be used to collect real time traffic information and further guide the building of smart cities with respect to reversible lane systems and movable bridges.
    Lastly, accurate landscape characteristics data acquired through UAVs can be taken into account to integrate better design quality and reduce cost. UAVs are capable of gathering key information to guide new infrastructure design.
    Constructions of large-scale infrastructures are intricate processes that need careful site survey, construction process monitoring, post-build checks and safety supervision. After project planning and design, detailed surveys are usually necessary to make a workable field construction plan. As mentioned previously, UAVs are efficient tools to survey construction sites. UAVs allow enhanced visibility which is more helpful in construction monitoring

    Construction

    UAVs linked with Building Information Modeling (BIM) will potentially improve construction productivity by monitoring not only construction process but also material delivery and equipment usage.
    UAVs coupled with visual equipment provide real-time view on sites that help to enhance safety. Multi drones can collaborate to lift relative heavy loads. Some counties also use drones as delivery tools to place cables in suspension bridges, which greatly improved the construction productivity.

    Maintenance

    Well maintenance infrastructures have reduced maintenance and repair cost and
    elongated service life. In order to inspect infrastructures, conventional means require trained
    workers and engineers to climb the structure to get desired information. This process could be
    time-consuming and unsafe, sometimes even dangerous. With the flying ability of drone
    platform, various detecting and surveying equipment can be used to monitor health conditions
    of infrastructures.
