At this special location, the weaving area is a recurrent traffic bottleneck. Numerous research activities have been conducted to improve traffic efficiency and sustainability at bottleneck areas. Variable speed limit control (VSL) is one of the effective control strategies. The primary objective of this paper is twofold. On the one hand, turbulent traffic flow is to be smoothed on the special weaving area of motorways and urban roads using VSL control. On the other hand, another control method is provided to tackle the carbon dioxide emission problem over the network. For both control methods, a multi-agent reinforcement learning algorithm is used (MAPPO: multi-agent proximal policy optimization). The VSL control framework utilizes the real-time traffic state and the speed limit value in the last control step as the input of the optimization algorithm. Two reward functions are constructed to guide the algorithm to output the value of the dynamic speed limit enforced within the VSL control area. The effectiveness of the proposed control framework is verified via microscopic traffic simulation using simulation of urban mobility (SUMO). The results show that the proposed control method could shape a more homogeneous traffic flow, and reduces the total waiting time over the network by 15.8%. In the case of the carbon dioxide minimization strategy, the carbon dioxide emission can be reduced by 10.79% in the recurrent bottleneck area caused by the transition from motorways to urban roads.}, year = {2023}, eissn = {2071-1050}, orcid-numbers = {Tettamanti, Tamás/0000-0002-8934-3653} } @article{MTMT:33930648, title = {Mathematical Description of the Universal IDM - some Comments and Application}, url = {https://m2.mtmt.hu/api/publication/33930648}, author = {Péter, Tamás and Háry, A and Szauter, Ferenc and Szabó, Krisztián and Vadvári, Tibor and Lakatos, István}, doi = {10.12700/APH.20.7.2023.7.6}, journal-iso = {ACTA POLYTECH HUNG}, journal = {ACTA POLYTECHNICA HUNGARICA}, volume = {20}, unique-id = {33930648}, issn = {1785-8860}, year = {2023}, eissn = {1785-8860}, pages = {99-115}, orcid-numbers = {Szabó, Krisztián/0000-0001-8761-6083; Vadvári, Tibor/0000-0001-5922-2204; Lakatos, István/0000-0002-3855-7379} } @inproceedings{MTMT:33661932, title = {Közúti hálózati modell alkalmazása a környezeti terhelések optimálására}, url = {https://m2.mtmt.hu/api/publication/33661932}, author = {Péter, Tamás and Háry, András and Szauter, Ferenc and Vadvári, Tibor and Lakatos, István}, booktitle = {XVI.

In order to achieve this objective, an essential component to be investigated is the catchment areas of these P&R facilities. However, a limited number of studies have applied the Geographic Information System (GIS) to study the spatial boundary accessibility of the catchment areas of P&R. This study aims to analyze the spatial boundary accessibility of the catchment areas of P&R facilities using three GIS methods. The first method uses geometric shapes to analyze the catchment areas of P&R facilities according to regular shapes, such as parabolas or circles. The market area is the second method used to analyze travel time via the tool ArcGIS Network Analyst to determine the catchment area of P&Rs. Finally, the dynamic accessibility method determines how accessible a facility can be through a study of the spatial boundary accessibility of P&Rs based on the travel time and distance between zones and P&R. The result shows that the static methods identify the spatial boundary accessibility through the calculation of the size of the shape of each P&R separately, while the dynamic method identifies the level of accessibility in detail for all P&R and also the accessibility of each zone to reach a facility. In conclusion, the dynamic accessibility method presents better accuracy than static methods in order to estimate the spatial boundary accessibility of the catchment area of P&Rs.}, year = {2022}, eissn = {1587-3811}, pages = {69-78} } @misc{MTMT:32784130, title = {A theoretical analysis of car emission levels related to the implementation of a Park and Ride in an urban environment}, url = {https://m2.mtmt.hu/api/publication/32784130}, author = {Ortega Ortega, Jairo Fabian and Tóth, János and Péter, Tamás}, unique-id = {32784130}, year = {2021} } @misc{MTMT:32784129, title = {Analyzing pollution reduction by combining the P&R system with electric vehicles}, url = {https://m2.mtmt.hu/api/publication/32784129}, author = {Ortega Ortega, Jairo Fabian and Tóth, János and Péter, Tamás}, unique-id = {32784129}, year = {2021} }
