Due to its key function and the nearby industrial areas, the traffic volume along Marato\u0144ska is already quite significant, even during off-peak hours. <\/p>\n\n\n\n<p>With plans to expand the industrial footprint in the area, the city decided to conduct a comprehensive simulation analysis using PTV Group&#8217;s tools and engineering expertise. For microsimulation, the Dynamic Assignment feature was chosen to enable realistic route selection based on varying traffic patterns.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-current-situation\"><strong>Current situation<\/strong><\/h2>\n\n\n\n<p>As a regional capital, Lodz is located near the geographic center of the country, about an hour from the capital, Warsaw. Historically a center of the textile industry, Lodz earned the nickname &#8220;The Polish Manchester&#8221; in the 19th century. Today, many old factories have been converted into cultural and commercial spaces. Lodz is also recognized as a UNESCO City of Film, attracting international festivals and boasting the longest shopping street in Europe.<\/p>\n\n\n\n<p>From a transportation perspective, Lodz is well-connected by rail and road, and is surrounded by highways and expressways that serve as bypasses for the city. Until recently, only the western side of the city lacked a bypass &#8211; this was solved by the introduction of the S14, which is now fully operational.<\/p>\n\n\n\n<p>One of the main routes to the S14 is via Marato\u0144ska Street, a 7-kilometer road that connects the inner-city bypass with neighborhoods and industrial areas up to the expressway. Due to its strategic role, Marato\u0144ska carries a variety of traffic types and a high volume of traffic throughout the day, especially heavy goods traffic.<\/p>\n\n\n\n<p>A short section of Marato\u0144ska has recently been upgraded to meet the requirements of the S14 junction, but traffic remains challenging due to early shift start times in nearby industries, resulting in up to six hours of high traffic volumes per day.<\/p>\n\n\n\n<p>Traffic to and from the industrial zone primarily flows along Golfowa Street, a narrow two-lane road that is not designed to handle this volume. With over 4,000 jobs currently located in the area and plans to expand to as many as 10,000 jobs, the city identified an urgent need for in-depth analysis.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Picture1.png\" rel=\"lightbox[25804]\"><img loading=\"lazy\" decoding=\"async\" width=\"527\" height=\"545\" src=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Picture1.png\" alt=\"\" class=\"wp-image-25805\" style=\"width:554px;height:auto\" srcset=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Picture1.png 527w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Picture1-348x360.png 348w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Picture1-193x200.png 193w\" sizes=\"auto, (max-width: 527px) 100vw, 527px\" \/><\/a><figcaption class=\"wp-element-caption\"><strong>LEGEND<\/strong><br><strong>Purple:<\/strong> Industrial area with growth potential<br><strong>Red:<\/strong> Marato\u0144ska Street, linking S-14 highway to Lodz<br><strong>Yellow:<\/strong> Golfowa Street, congested due to industrial facilities<br><strong>Green:<\/strong> Proposed connection to Marato\u0144ska Street to relieve congestion in Golfowa (Scenario 3 only)<br><strong>Dotted lines:<\/strong> Other planned roads<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-simulation-goals\"><strong>Simulation goals<\/strong><\/h2>\n\n\n\n<p>From the start, the plan was to perform both strategic and microsimulation analyses:<\/p>\n\n\n\n<p><a href=\"https:\/\/www.ptvgroup.com\/en\/products\/ptv-visum\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PTV Visum<\/strong><\/a> strategic simulation would help estimate new traffic volumes and delays associated with the industrial expansion.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.ptvgroup.com\/en\/products\/ptv-vissim\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PTV Vissim<\/strong><\/a> microsimulation would then test detailed design changes, focusing on the introduction of an alternative route to relieve Golfowa Street.

All scenarios used <a href=\"https:\/\/www.youtube.com\/watch?v=eoqIQEiyjEg\" target=\"_blank\" rel=\"noreferrer noopener\">Dynamic Assignment<\/a>, PTV Vissim&#8217;s robust route selection method, which allowed estimating the influence of possible route choices in the simulated area, a crucial factor especially for scenario 3.&nbsp;<\/p>\n\n\n\n<p>Scenario 3, using Dynamic Assignment, showed that the new link road significantly reduced congestion on Golfowa Street. Dynamic Assignment, unlike Static Assignment, allows paths to be adjusted based on real-time delays and cost perspectives, providing more realistic route-choice behavior.<\/p>\n\n\n\n<p>Once the strategic forecasts were complete, PTV Vissim was used to create an accurate microsimulation of Marato\u0144ska and the surrounding area, including the industrial park and highway interchange. Using demand derived from strategic forecasts, it was possible to recreate and further analyze possible outcomes.<\/p>\n\n\n\n<p>Unlike the classic Static Assignment in PTV Vissim, Dynamic Assignment requires a matrix or series of matrices representing the trips between specific edges of the modeled area, and allows dynamic route selection based on iterative best-path searches. This method accounts for delays and traveler costs, making it ideal for testing alternative routes such as those in Scenario 3. For consistency, Dynamic Mapping was used across all scenarios.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-results-of-vissim-simulations\"><strong>Results of Vissim simulations<\/strong><\/h3>\n\n\n\n<p>The results confirm the initial picture from the strategic simulation.<\/p>\n\n\n\n<p><strong>Scenario 1<\/strong> resulted in severe delays with significant queuing phenomena in many sections of the network, including Marato\u0144ska and Golfowa.<\/p>\n\n\n\n<p>In <strong>Scenario 2<\/strong>, the introduction of a new roundabout and the widening of Marato\u0144ska to 4 lanes in each direction improved traffic conditions, but delays and queues weren&#8217;t eliminated.<\/p>\n\n\n\n<p><strong>Scenario 3<\/strong>, which acts as a further extension of Scenario 2 with the new link connected to the introduced turbo roundabout, showed the best results in traffic flow improvement, providing a network design that meets future demand. Below, selected results show the difference between the scenarios for the AM peak hour.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results.png\" rel=\"lightbox[25804]\"><img loading=\"lazy\" decoding=\"async\" width=\"1110\" height=\"535\" src=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results-1110x535.png\" alt=\"PTV traffic simulations in Lodz\" class=\"wp-image-25829\" srcset=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results-1110x535.png 1110w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results-640x309.png 640w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results-768x370.png 768w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results-1536x741.png 1536w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results-300x145.png 300w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results.png 2038w\" sizes=\"auto, (max-width: 1110px) 100vw, 1110px\" \/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results_2.png\" rel=\"lightbox[25804]\"><img loading=\"lazy\" decoding=\"async\" width=\"966\" height=\"624\" src=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results_2-966x624.png\" alt=\"PTV traffic simulations in Lodz\" class=\"wp-image-25831\" srcset=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results_2-966x624.png 966w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results_2-558x360.png 558w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results_2-768x496.png 768w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results_2-1536x992.png 1536w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results_2-300x194.png 300w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/11\/Vissim_final_results_2.png 1648w\" sizes=\"auto, (max-width: 966px) 100vw, 966px\" \/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-conclusion\"><strong>Conclusion<\/strong><\/h2>\n\n\n\n<p>Lodz, Poland is tackling congestion on Marato\u0144ska Street, a major route to the S14 highway, as industrial growth increases traffic demand.<\/p>\n\n\n\n<p>The city used PTV Visum to model <strong>strategic scenarios<\/strong> to forecast traffic volumes and test potential improvements, including road expansions and new links.<\/p>\n\n\n\n<p>PTV Vissim <strong>microsimulation<\/strong>, with its Dynamic Assignment feature, then analyzed realistic route choices based on varying traffic conditions, confirming that adding a new link road and a turbo roundabout would effectively reduce congestion.<\/p>\n\n\n\n<p>Based on these findings, Lodz is moving forward with targeted infrastructure upgrades to meet future needs.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column cta-box is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<div class=\"wp-block-cover\"><img loading=\"lazy\" decoding=\"async\" width=\"1254\" height=\"836\" class=\"wp-block-cover__image-background wp-image-25406\" alt=\"\" src=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/10\/iStock-1312502184.jpg\" data-object-fit=\"cover\" srcset=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/10\/iStock-1312502184.jpg 1254w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/10\/iStock-1312502184-540x360.jpg 540w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/10\/iStock-1312502184-936x624.jpg 936w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/10\/iStock-1312502184-768x512.jpg 768w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2024\/10\/iStock-1312502184-300x200.jpg 300w\" sizes=\"auto, (max-width: 1254px) 100vw, 1254px\" \/><span aria-hidden=\"true\" class=\"wp-block-cover__background has-background-dim-80 has-background-dim wp-block-cover__gradient-background has-background-gradient\" style=\"background:linear-gradient(135deg,rgb(66,104,249) 28%,rgb(41,224,133) 88%)\"><\/span><div class=\"wp-block-cover__inner-container is-layout-constrained wp-block-cover-is-layout-constrained\">\n<p class=\"has-text-align-center\" style=\"font-size:24px;font-style:normal;font-weight:700\">White Paper: Transport Modeling<\/p>\n\n\n\n<p class=\"has-text-align-center\">How do you create a transportation model?
