Broadband highways are being built in major cities around the world to combat traffic congestion. At the same time, existing buildings are demolished or powerful overpasses are raised above them. However, it often turns out that newly created highways quickly exhaust their capacity, and traffic jams are formed on them again. This situation indicates that increasing the capacity of the highway does not solve the problem of traffic jams, but often aggravates it, since as a result of this increase, even more cars are drawn to the highway from adjacent territories, often exceeding their current capacity. At the same time, the streets in the surrounding areas are empty and their potential is not used to the full extent. This situation has arisen due to the disruption of the city road network by lengthy obstacles in the form of ravines, rivers, floodplains of small rivers, and railways. This situation can be corrected by "stitching" the streets over the gaps by building bridges and overpasses with a capacity corresponding to the capacity of the "stitched" streets. Most of the gaps fall on relatively small streets, which approach the banks of fairly wide floodplains of small rivers and streams, and this makes it advisable to build mainly small (with a span of 20-25 m) and relatively inexpensive bridges, with the number of spans sufficient to cover the floodplain and reach the levels of road surfaces of connected streets. There will be several hundred such bridges over the river barriers in a large city, for example, Moscow, and several hundred more, taking into account the required number of them over the railways, and in the end, about a thousand. It is proposed to erect bridge buildings instead of simple road bridges. Such structures combine two city functions; the first of them is transport, the second is public, residential, or economic, depending on the needs of the city and the environmental situation at the construction site. An important requirement for the second function is a quick return on the financial assets invested in the construction and income from the operation of the building acceptable to the investor. The bridge part of a bridge building should become the property of the city.

The foundation of the city of Recopolis on the initiative of King Liuvigild in ad 578 is the clearest material expression of the participation of the Visigothic state in urban development and in the creation of power landscapes. The ex novo construction of the city – city walls, palatial complex, elite houses, commercial and industrial buildings, hierarchical organization of space – and its impact on the wider territory, with the reorganization and renovation of the road network and creation of new rural settlements, was a clear demonstration of political prowess and an expression of the tax-collecting power of the state. Contextualizing these features within the broader landscape helps in understanding the spatial and social inequality that characterized the beginning of the early medieval period.

Abstrak: Pasar sangatlah identik dengan pusat keramaian, karena pasar merupakan pusat perdagangan yang terletak di pusat kota yang sering disebut juga dengan kawasan Central Bussiness District (CBD). Karena pasar merupakan pusat keramaian sehingga mengundang banyak masyarakat untuk datang ke kawasan tersebut sehingga menimbulkan kemacetan arus lalu lintas, akibat tidak terkendalinya arus lalu lintas di sekitar pasar. Kemacetan arus lalu lintas salah satunya akibat dari tidak terkendalinya parkir sehingga membuat kondisi parkir di sekitar daerah tersebut menjadi semakin semrawut. Pasar Aceh merupakan salah satu pusat perdagangan terbesar dan yang paling berkembang di kota Banda Aceh. Semakin berkembangnya kawasan Pasar Aceh membuat aktivitas pergerakan masyarakat semakin meningkat, sehingga membuat menurunnya tingkat pelayanan jalan di kawasan tersebut,  yang diakibatkan oleh kendaraan yang berjalan lambat, parkir, pejalan kaki dan pedagang kaki lima. Pasar Aceh memiliki fasilitas ruang parkirnya. Setelah disediakan ruang parkir pada gedung Pasar Aceh (off-street parking) yang baru ini ternyata masih banyak masyarakat yang lebih memilih parkir dibadan jalan (on-street parking), sementara pelataran parkir pada gedung Pasar Aceh belum habis terisi penuh, sehingga masih terjadi kemacetan dan kesemrawutan lalu lintas yang diakibatkan oleh banyaknya pengguna jalan yang menggunakan badan jalan sebagai tempat parkir. Tujuan penelitian ini adalah : (1) mengevaluasi kinerja jalan yang terbebani oleh kendaraan yang melintasi jalan di kawasan Pasar Aceh, (2) mengevaluasi kebutuhan ruang parkir yang optimal untuk melayani para pengunjung Pasar Aceh dan (3) mengidentifikasi permasalahan-permasalahan yang timbul akibat on-street parking berdasarkan persepsi masyarakat. Sehingga diharapkan dapat direncanakan manajemen parkir yang baik untuk masa yang akan datang.Kata kunci : tingkat pelayanan jalan, permasalahan parkir, persepsi masyarakat, manajemen parkirAbstract: The market is very synonymous with the center of the crowd, because the market is a trading center located in the city center which is often referred to as the Central Bussiness District (CBD). Because the market is a center of crowds that invites many people to come to the area, causing traffic congestion, due to uncontrolled traffic flow around the market. One of the traffic jams is due to uncontrolled parking, making parking conditions around the area increasingly chaotic. Aceh Market is one of the largest and most developed trade centers in the city of Banda Aceh. The increasing development of the Aceh Market area has made community movement activities increasingly increasing, which has caused a decline in the level of road services in the area, which is caused by vehicles that run slowly, parked, pedestrians and street vendors. Aceh Market has its parking facilities. Having provided parking space on the new Pasar Aceh (off-street parking) building it turns out that there are still many people who prefer on-street parking, while the parking lot on the Aceh Market building has not been fully filled, so traffic jams still occur and the chaos of traffic caused by many road users who use the road as a parking lot. The objectives of this study are: (1) evaluating road performance burdened by vehicles crossing the road in the Aceh Market area, (2) evaluating optimal parking space requirements to serve Aceh Market visitors and (3) identifying problems arising from -street parking based on people's perception. So it is expected that good parking management can be planned in the future. Keywords: level of road service, parking problems, public perception, parking management

An intensive increase in road transport, particularly individual, in recent years has led to such consequences as increased time spent on travel, the number of forced stops, traffic accidents, the occurrence of traffic jams on the road network, reducing traffic speed and a deteriorated urban road network in cities. The most effective method for solving these problems is the use of graph theory, the main characteristics of which is reliability, durability and accessibility of a free as well as loaded network. Based on their analysis the methods for network optimization are proposed.

Abstract. Climate change leads to an increasing number of flood events that poses threats to a large share of the global population. In addition to direct effects, flooding leads to indirect effect due to damages of the road infrastructure that might limit accessibility of health sites. For disaster preparedness it is important to know how flood events impact accessibility in that respect. We analyzed this at the example of the capital of Indonesia, Jakarta based on the flood event of 2013. The analysis was based on information about the road network and health sites from OpenStreetMap. We assessed impacts of the flood event by comparing centrality indicators of the road network as well as by an accessibility analysis of health sites before and during the event. The flooded areas were home to 2.75 million inhabitants and hosted 79 clinics and hospitals. The flood split the road network into several subgraphs. The city center maintained its importance for time-efficient routing as well as for easily accessible healthcare but might be prone to traffic congestion after such an event. Indirect effects via interrupted road traffic through flooded areas affected around 1.5 million inhabitants and led to an increase of travel time to the nearest hospital by five minutes based on normal traffic conditions.

Modeling Transport

Managing urban networks during traffic congestion requires the use of a dynamic model that allows you to simulate real situations with traffic flows with long queues and responses. To conduct experimental research in this area, it is possible to use a mesoscopic system for simulating traffic with calibration and taking into account the characteristics of the road. All supply and demand parameters (use of detectors, travel time) must be calibrated at the same time. In this study, calibration was performed using the route selection model, given overlapping routes

Traffic Jams

Managing the frequent traffic congestion (traffic jams) of the road networks of large cities is a major challenge for municipal traffic management organizations. In order to manage these situations, it is crucial to understand the processes that lead to congestion and propagation, because the occurrence of a traffic jam does not merely paralyze one street or road, but could spill over onto the whole vicinity (even an entire neighborhood). Solutions can be found in professional literature, but they either oversimplify the problem, or fail to provide a scalable solution. In this article, we describe a new method that not only provides an accurate road network model, but is also a scalable solution for identifying the direction of traffic congestion propagation. Our method was subjected to a detailed performance analysis, which was based on real road network data. According to testing, our method outperforms the ones that have been used to date.

New Buildings

The spaces of Russian cities (the centers of the subjects of the Federation - first of all) have changed significantly due to the growth in housing construction over the past one and a half - two decades. More than 100, mainly multi-storey residential buildings have been built and are under construction in the capital of the Udmurt Republic - Izhevsk. The settlement of new buildings will significantly change the geography of the settlement of the population and the density of the population in individual neighborhoods of the city. The rapid mass construction of buildings creates, in particular, a transportation problem. The transport system is one of the most important components of urban infrastructure. The changes in the geography of the population settlement will lead to changes in the geography of the intensity of traffic flows, to which the city’s road network may not be ready. The problem of such unavailability is due to financial, administrative and technical reasons. After the first and second phases of construction of housing complexes the situation on many important sections of the Izhevsk road network will become significantly more complicated, and the likelihood of road congestion will increase in the next 4-5 years. The authors have developed and applied a methodology for assessing existing traffic flows along the road network, as well as a method for predicting the intensity and directions of prospective traffic flows that will arise during the implementation of construction phases. The “12 micro district” of the city of Izhevsk as a geographical object of research was chosen. The assessment of existing traffic flows was carried out - at the first stage. A forecast was made of traffic on the road network inside and around the perimeter of the “12 micro district” - at the second stage. The results obtained have made it possible to identify the most problematic sections of the street and road network at present and in the near future. The recommendations to overcome the problem situations that were taken to action by the developer were made.
