Prioritizing public transport is one of the most effective measure to increase the attractiveness and competitiveness of public transport in relation to individual vehicles. The main goal of this study was to examine the possibilities for reducing the travel time of tram vehicles by giving priority at signalized intersections in terms of sharing the traffic lane with personal vehicles and under conditions of strong conflict flows with private transport. For this purpose, we used the simulation tool VISSIM and its module EPICS. A methodology for determining weighting factors for prioritizing public transport flows was developed based on conflicting passenger flows in public transport vehicles and passenger cars. Three scenarios were tested in the study area: (1) “do nothing”; (2) unconditional priority; and (3) conditional priority. The results showed that unconditional priority led to unsustainable traffic conditions for personal vehicles and public transport. In contrast, conditional priority reduced the travel time of public transport on certain corridors by between 7.64% and 18.76% in the morning peak period, and 5.60% to 22.50% in the afternoon peak period.

Decision-making to improve the functioning of route systems is an extremely necessary, but at the same time difficult task, as it determines the overall socio-economic development of the city, the stability and safety of its transport complex. The purpose of this work is to establish patterns of formation and distribution of passenger flows for the transport network of the city with a description of models of their operation. The traditional approach to determining the concentration of travel is described by "synthetic" models, such as gravity. A practical solution to the problems of transport planning is the modeling of behavioral demand, which is based on the concept of attractiveness function. The load of the transport network is determined by the number of vehicles on it. Download simulation is the distribution of inter-district correspondence along specific paths connecting district pairs. In normative models, the distribution of traffic flows is based on the optimization of some global criterion that characterizes the efficiency of the entire network. The descriptive approach is based on the principle according to which each participant seeks to minimize their own costs. The most effective is the model of finding the equilibrium distribution. One of the variants of which is used to distribute users of one class. In this way, the location of transport interchanges in the transport infrastructure of the city mainly determines their transport structure. The distribution of passenger correspondence between interacting infrastructure objects is described by a gravitational model. The equilibrium distribution search model should be used as a task to optimize the distribution of traffic flows.

The article discusses development of a system of transport and interchange hubs (TIH). The need to create TIHs is due to an opportunity to increase efficiency of passenger flows in the urban public transport system, to reduce travel time for passengers, to ensure comfortable and safe conditions for transfer, and to improve quality of service to the population.  The objective of the research is to develop methods that allow solving the problem of optimal selection of TIH locations in any city according to the economic criterion and the criterion of the average travel time using the methods of mathematical modelling. The technique comprises search for optimal travel routes in the city and identification of effective interchange hubs using the developed software product called «Efficient transfers». Efficient transfer hubs with maximum passenger traffic are candidates for TIH locations. The work describes calculations made according the proposed methods and optimal options for location of this in the city of Samara considering limited funds, reduction in travel time and in the number of passengers using these TIHs. The research also resulted in obtaining the dependence of reduction in the average time of an urban trip on the number of TIHs.

The article presents a comparative analysis of fortification art monuments in such East countries from Ancient Egypt to medieval China. An attempt is made to identify the main stages of the fortification development from a stand-alone fortress (citadel, fort) to the most complex systems of urban and border fortifications, including moats, walls and gates, battle towers. It is shown that the nature of these architectural structures is determined by the status of the city or settlement, its natural landscape, building structures and materials, the development of military and engineering art. The materials from poliorceticon (Greek: poliorketikon, poliorketika), illustrate the main types of siege machines and mechanisms. The advantages and disadvantages of boundary shafts and long walls (limes). The most striking examples are the defensive systems of Assyria, New Babylon, Judea and Ancient China.

New vertical housing developments in Guadalajara (Mexico) are reaching the city center as a response for redensification after many years of expansion of the urban area characterized by a suburban, low density and fragmented pattern. This horizontal growth, dominated by use of the automobile as prevailing mode of transport, has proven to be unsustainable not only from an environmental point of view, but also from a social perspective where the “human scale” of the city has been affected, same as the daily life of its inhabitants. On the other hand, vertical housing proposals are by their very nature associated with concepts of redensification, compact city and collective living; the aim of this article is to analyze some new housing developments in Guadalajara downtown in order to evaluate to what extent the new buildings embody a more sustainable, livable and collective dwelling, to discuss findings, successes and failures and thus be able to contribute some conclusions and open a broader reflection about contemporary housing, urban density and downtown redevelopment in Latin America cities through collective and sustainable dwelling.

This study analyses the changes in intra-city housing values in response to improved inter-city connection brought by high-speed rail (HSR), using the opening of the Hangzhou–Fuzhou–Shenzhen Passenger Dedicated Line (HFSL) in Shenzhen, China, as an example. The opening of the HFSL and its integration into the local metro network at Shenzhen North Station provide exogenous intra-city variations in access to the surrounding economic mass. With a difference-in-differences approach, we find that the HFSL showed a negative local effect as housing values declined by 11.5%–13.3% in the proximity of Shenzhen North Station relative to areas further from the station after the opening, possibly due to the negative externalities of the HFSL. The HFSL effect can spread along the metro network and lead to, on average, a 7% appreciation of housing values around metro stations (network effect). The direction and strength of the network effect vary by metro travel time between Shenzhen North Station and metro stations. Housing values decreased by 7.7% around metro stations within 5–15 minutes of metro travel time but increased by 63.6%, 16.6% and 29.2% around metro stations within 15–25, 25–35 and 35–45 minutes of metro travel time to Shenzhen North Station, respectively. The HFSL effect on housing values diminishes when the rail travel time is above 45 minutes. We interpret these findings as evidence of the redistribution effect in the city related to HSR connection.

<p>Cycling is a memory of the past for most of us, the lack of support from the authorities on the cycling infrastructure made it difficult to attract people to cycle in the city. Urban sprawl, traffic congestion, car dependency, environmental pollution and public health concerns have pressured cities around the world to consider reintegrating cycling into the urban environment.  Design as a research method was utilised to investigate the effectiveness of design methodology and workflow for cycling infrastructure from an architecture and design perspective. Using Wellington City as a design case study, this research aimed to improve the legibility, usability and the image of cycling as a mode of transport in the city. To achieve this, a customisable graphical design framework and branding strategies were developed to structure and organise the design components within cycling infrastructure. The findings from the iterative design processes were visualised through the appropriate architectural and presentation conventions.  This research provided an unique architectural perspectives on the issues of cycling infrastructure; the results would support the transportation advisers and urban planners to further the development and integration of cycling, as a viable mode of transport, within the city.</p>

<p>In 1840, the inauguration of the Great Western Railway in South England connecting London and Bristol, changed part of the outskirts of Bristol to a major railway hub and home of many rail-related activities. An area behind the station in between the railway, the River Avon and the Bath road, known as Temple Island, became restricted to rail use (workshops, depots or sheds) for more than 150 years, making it inaccessible and unattractive as the railway use decreased. The transformation of this area into a new centrally located neighbourhood is one of the most important urban development projects currently planned in Bristol. The new St Philips footbridge spans the River Avon, contributing to accessibility to the site and increasing the sustainable transport network of the city. The bridge, a 50m-span and 4-m wide steel beam with a forked geometry, seamlessly hosts a ramp for disabled and cyclists and a staircase to maximise functionality. The design approach to generate its shape was at the same time structural, aesthetical, and functional, innovatively solving a complex crossing problem.</p>
