Traffic signal priority issues have been a research subject for several decades in Poland and worldwide. Traffic control algorithms have evolved considerably during this period and have become increasingly advanced. Most of them operate within coordinated street sequences, which adds to their complexity. Tramway priority affects traffic conditions for other road users, so many aspects must be taken into account when choosing a priority solution. Typically, one of the main criteria for evaluating the effectiveness of priority is reducing travel time for the priority vehicle while ensuring that the travel times of other traffic participants through the intersection are maintained or slightly deteriorated. However, the energy aspects are often overlooked. This publication aims to investigate how local priority for tramways in traffic signals of coordinated streets affects energy consumption for tramway traction needs. The study was conducted using a microscopic modeling method with PTV Vissim software (ver. 2021). The models were built for coordinated sequences with different levels of priority. Real traffic control algorithms with priority were implemented into the model on the sequence of Marymoncka Street and Grochowska Street in Warsaw. Then, by introducing changes to the parameters of the algorithms, their effect on traffic characteristics, including estimated power consumption, was studied. The results obtained from the computer simulation were statistically processed using R software (ver. 4.3.2). The analysis results prove the effectiveness of tramway priority operation, show its impact on electricity consumption, and allow us to determine the limits of its effective application. Thus, they complement the knowledge of the impact of tramway priority on traffic. The research results also have practical value, as they help us to make rational decisions in the process of designing traffic control algorithms at intersections with a multi-criteria approach.

“…Measurement of compactness can provide insight into the rationality of the spatial structure of a central station (Kain, 2022). At present, compact cities and central station built environments are mainly studied through urban traffic-driven development strategies (Ito and Kawazoe, 2022). Sustainability of compact cities (Kjaeras, 2020), index analyses of a variety of compact city elements (Ting, 2021).…”

Sustainable urbanization has entered an intensive land development phase in China. Current rail transit developments are forcing urbanization researchers to focus on conflicts with the built environment. In order to achieve resource systematization and spatial intensification, this paper explores regional transformation in Chengdu, a "new first-tier" city in China. Research objects are selected based on the fact that these areas have rail transit systems that interact with existing built-up areas and there is an intent for intensive urbanization. Studies reveal that compact city development is closely associated with transit-oriented development (TOD). In the strategic region of central stations, disorderly land use has been exacerbated by unclear pathways for density growth and functional combination patterns. More research parameters and thresholds are needed to construct a quantitative framework and construction standards, while drawing on Shanghai's successful development in strategic areas of central stations, which is aligned with China's national conditions. Therefore, based on the quantification objectives of density and function derived from the compact city theory, this paper explores the differences in intensive urbanization indicators between the strategic region of central stations of Chengdu and Shanghai, and analyzes the indicator thresholds for different regional types (new urban areas and old urban areas) according to the principles of normal distribution, providing quantitative support for the intensive development of strategic region of central stations in Chengdu.
