Traditional terminal logistics distribution in urban areas is mainly concentrated on the ground, which leads to increasingly serious air pollution and traffic congestion. With the popularization of unmanned aerial vehicle (UAV) techniques and the reform of low altitude airspace, terminal logistics distribution is expected to be carried out by drones. Therefore, it is of great significance to construct a reasonable air route network for logistics UAV to ensure the safety and efficiency of operations. In this paper, a single route planning model and an air route network planning model for UAV were constructed by fully considering the complex urban low altitude environment, the flight performance of UAV and the characteristics of logistics tasks to regulate the flights of drones. Then, taking Jiangjun Road Campus of Nanjing University of Aeronautics and Astronautics as an example, the improved cellular automata (CA) was adopted to search for the optimal route between different waypoints, and the optimal spanning tree algorithm was used to construct the route network. The experimental results demonstrated that the improved CA could greatly reduce search time and obtain the optimal route while enhancing safety. With the satisfaction of the voyage, the needs of logistics and distribution constraints, a network that had smaller intersection points and redundancy was generated. The models and core ideas proposed in this paper can not only regulate operation of drones but also provide a solid foundation for the distribution of logistics UAV in the future.

Underground logistics system (ULS) tends to alleviate traffic congestion, increase city logistics efficiency, mitigate the negative effects of traditional logistics processes, and improve the sustainability of urban areas. However, the relatively high cost and risk of underground construction are serious obstacles to implementing ULS. Integrating ULS into modern metro system (M-ULS) is considered to be feasible and efficient to solve this problem. This paper aims at developing a metro system-based ULS network planning method. First, an evaluation model of underground freight volume was proposed considering service capacity, freight flow, and regional accessibility. Second, a set of mixed integer programming model was developed to solve the problem of optimal nodes’ location-allocation (LAP) in the network. Then, a hybrid algorithm was designed with a combination of E-TOPSIS, exact algorithm, and heuristic algorithm. Finally, two lines of Nanjing Metro were selected as a case to validate the proposed planning method. The results showed that the new system can significantly reduce the construction costs of ULS and alleviate traffic congestion. Moreover, the potential of metro stations and underground tunnels can be fully exploited to achieve higher logistics benefits.

The combination of satellite direct reception and terrestrial 5G infrastructure is essential to guarantee coverage in satellite based-Internet of Things, mainly in smart cities where buildings can cause high power losses. In this paper, we propose an accurate and fast graphical method for predicting the satellite coverage in urban areas and SatCom on-the-move scenarios. The aim is to provide information that could be useful in the IoT network planning process, e.g., in the decision of how many terrestrial repeaters are really needed and where they should be placed. Experiments show that the shadowed areas predicted by the method correspond almost perfectly with experimental data measured from an Eutelsat satellite in the urban area of Barcelona.

AbstractThe Reduce performance of urban public transport in Jember can not separated from several factors, among other are less convenient conditions in terms of service, overlapping route, no improvement for route network made by local authority, and cheap moator loans which cause many poeple use motor vehicles. The Worst effect if this thing continous increase population of motor vehicles. At the same time nowdays, new land-use patterns have grown in urban areas which potentially have large demand but still unserved by public transport. Seeing these problems, public branch route network planning is needed as well as the requirment of public transportation fleets in accordance with the legislation. From the planning conducted, it was found 8 plan branch routes and the fleet needs.From such palnning it was expected that it can reduce the overlapping route and accomodate all urban areas in order to served by public transport. Keyword: branch route network planning, legislation AbstrakMenurunnya kinerja angkutan umum perkotaan jember tidak lepas dari beberapa faktor antara lain kondisi kurang nyaman dalam segi pelayanan, overlapping trayek, belum dilakukan perbaikan jaringan trayek oleh pihak berwenang, dan kredit motor yang murah sehingga masyarakat banyak yang menggunakan kendaraan bermotor. Dampak terburuk bila hal ini terus berlanjut, populasi kendaraan bermotor akan meningkat tiap tahunnya. Kemacetan lalu lintas, pemborosan BBM serta polusi udara juga akan meningkat. Disaat yang sama saat ini mulai tumbuh pola tata guna lahan baru di wilayah perkotaan yang berpotensi demand besar namun belum terlayani angktan umum. Melihat masalah tersebut perlu dilakukan sebuah perencanaan jaringan trayek angkutan umum ranting dan kebutuhan armadanya yang sesuai dengan konsep perundang-undangan. Dari perencanaan yang dilakukan didapatkan 8 rute rencana serta kebutuhan armadanya. Diharapakan dari perencanaan tersebut dapat mengurangi overlapping dan mengakomodasi seluruh wilayah perkotaan agar terlayani oleh angkutan umum.Kata kunci: Perencanaan jarigan trayek ranting, Konsep peraturan perundang-undangan

Micromobility has a high potential to change mobility habits towards the use of sustainable transport modes. The shared mobility paradigm encourages the development of new mobility services, such as bike and e-scooter sharing, potentially reducing the need of car ownership, enlarging the accessibility of public transport and enriching the transport options needed to exploit Mobility as a Service solutions. While bike-sharing services have been used in urban areas for many years, shared e-scooter services (and private e-scooters) have been spreading only in the last few years. Due to the novelty of this mode, few attempts have been made for proper micromobility network planning. This paper proposes a multicriteria GIS-based analysis aimed at planning priority networks for e-scooters, focusing on safety, transport and land use characteristics. The case study is Catania, a medium-sized city in southern Italy, which suffers from a lack of adequate infrastructures for such sustainable modes of transport. By applying the methodology, it is possible to prioritise the road network elements that better fit the needs of e-scooters, thus paving the way for suitable infrastructures and network planning.

Cannabis use does not show homogeneous patterns in a country. In particular, urbanization appears to influence prevalence rates, with higher rates in urban areas. A hierarchical linear model (HLM) was employed to analyze these structural influences on individuals in Switzerland. Data for this analysis were taken from the Switzerland survey of Health Behavior in School-Aged Children (HBSC) Study, the most recent survey to assess drug use in a nationally representative sample of 3473 15-year-olds. A total of 1487 male and 1620 female students indicated their cannabis use and their attributions of drug use to friends. As second level variables we included address density in the 26 Swiss Cantons as an indicator of urbanization and officially recorded offences of cannabis use in the Cantons as an indicator of repressive policy. Attribution of drug use to friends is highly correlated with cannabis use. The correlation is even more pronounced in urban Cantons. However, no association between recorded offences and cannabis use was found. The results suggest that structural variables influence individuals. Living in an urban area effects the attribution of drug use to friends. On the other hand repressive policy does not affect individual use.
