In addition, riders entering from either side of the station have an elevator closest to their respective entrances, decreasing wait times.<\/span>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The entrance on the Str. des 17. Juni (South) side was widened, which is also the wheelchair accessible entrance to the elevator but is very narrow. Currently, a wheelchair user would need to wait for the stream of people to pass when a train arrives before they can go to the elevator.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Typically, elevator shafts in metro stations are designed to accommodate standard elevator sizes, which often range from 1.5 meters to 2.5 meters in width and depth, with heights that can vary significantly depending on the number of floors served. For instance, a common dimension for a single elevator shaft is approximately 1.6 meters by 1.6 meters, which is suitable for a standard passenger elevator (Passi et al., 2021). A commercial elevator typically measures 5 feet by 7 feet (or about 1.5 meters by 2.1 meters) to 8 feet by 8 feet (or about 2.4 meters by 2.4 meters). These elevator dimensions can vary based on the specific needs of the building, the passenger capacity, and local building codes.<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Due to the location of the wastewater tanks in the basement, noise in the neighborhood is reduced.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Additional speakers for auditory arrival\/departure information are to be added for visually impaired riders. Downstairs, some LCD signs for current arrivals\/departures should also be added in the final stages of the station upgrade.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The pedestrian crosswalk lights should be re-timed to avoid an observed effect in the current timing scheme, which is that the average pedestrian cannot cross the whole\u00a0 Str. des 17. Juni in the allotted time and must wait for the lights to turn green a second time (or more frequently, run across while there is no car). The timing should be optimized for pedestrians to encourage multimodal transportation over car traffic and prioritize pedestrian safety (so that pedestrians don\u2019t have to crowd in the middle island or feel the need to run across the street).<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">In the end, three visually similar solutions were created to the parametric model, called \u201csmall,\u201d \u201cmedium,\u201d and \u201clarge,\u201d corresponding to expected passenger volume and budget for the redesign. The input parameters are summarized in Table 1 below. The &#8220;small&#8221; solution is shown in the screenshots of the model on this page.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Table 1: Input parameter values by design option in the combined parametric model<\/span><\/p>\n<p><a href=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/table-1.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-23545\" src=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/table-1.png\" alt=\"table-1\" width=\"1531\" height=\"216\" srcset=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/table-1.png 1531w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/table-1-300x42.png 300w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/table-1-1024x144.png 1024w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/table-1-520x73.png 520w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/table-1-740x104.png 740w\" sizes=\"auto, (max-width: 1531px) 100vw, 1531px\" \/><\/a><\/p>\n<p><a href=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-22350\" src=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s2.jpg\" alt=\"s2\" width=\"1282\" height=\"576\" srcset=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s2.jpg 1282w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s2-300x135.jpg 300w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s2-1024x460.jpg 1024w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s2-520x234.jpg 520w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s2-740x332.jpg 740w\" sizes=\"auto, (max-width: 1282px) 100vw, 1282px\" \/><\/a>\u00a0Figure 2: Underground view of the station upgrade with wastewater treatment (sedimentation tank and sludge digester)<\/p>\n<p><a href=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s4.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-22351\" src=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s4.jpg\" alt=\"s4\" width=\"1286\" height=\"527\" srcset=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s4.jpg 1286w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s4-300x123.jpg 300w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s4-1024x420.jpg 1024w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s4-520x213.jpg 520w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2025\/02\/s4-740x303.jpg 740w\" sizes=\"auto, (max-width: 1286px) 100vw, 1286px\" \/><\/a>Figure 3: Aerial view of the station upgrade with road, bridge, and station roof<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The model can be downloaded here: link The challenge for the combined parametric model was to make an inclusive and\u00a0 environmentally-friendly upgrade of the existing Tiergarten S-Bahn station with a water reclamation plant, highway underneath<a class=\"read-more\" href=\"http:\/\/141.23.68.248\/wp\/?page_id=22337\">Continue reading<\/a><\/p>\n","protected":false},"author":236,"featured_media":0,"parent":19684,"menu_order":0,"comment_status":"closed","ping_status":"open","template":"","meta":{"footnotes":""},"class_list":["post-22337","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"http:\/\/141.23.68.248\/wp\/index.php?rest_route=\/wp\/v2\/pages\/22337","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/141.23.68.248\/wp\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"http:\/\/141.23.68.248\/wp\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"http:\/\/141.23.68.248\/wp\/index.php?rest_route=\/wp\/v2\/users\/236"}],"replies":[{"embeddable":true,"href":"http:\/\/141.23.68.248\/wp\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=22337"}],"version-history":[{"count":11,"href":"http:\/\/141.23.68.248\/wp\/index.php?rest_route=\/wp\/v2\/pages\/22337\/revisions"}],"predecessor-version":[{"id":23547,"href":"http:\/\/141.23.68.248\/wp\/index.php?rest_route=\/wp\/v2\/pages\/22337\/revisions\/23547"}],"up":[{"embeddable":true,"href":"http:\/\/141.23.68.248\/wp\/index.php?rest_route=\/wp\/v2\/pages\/19684"}],"wp:attachment":[{"href":"http:\/\/141.23.68.248\/wp\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=22337"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
