Drivers inch through pinch points with almost no margin for error.<\/p>\n\n\n\n<p>In a place like this, static sketches and averages miss the interactions that decide <a href=\"https:\/\/blog.ptvgroup.com\/en\/user-insights\/how-microsimulation-reduces-risk-in-complex-urban-projects\/\" target=\"_blank\" rel=\"noreferrer noopener\">safety and flow<\/a>. That\u2019s why we turned to behaviour\u2011level microsimulation in PTV Vissim. The microsimulation reproduces the movement patterns of all road users on a microscopic scale and enables scenario\u2011based evaluation before implementation.<\/p>\n\n\n\n<p>Bradford-on-Avon is a historic market town in west Wiltshire, south-west England. Despite modest population, its street pattern and heritage constraints create mobility pressures more typical of far larger towns.<\/p>\n\n\n\n<p>In 2021, the Town Council consulted residents on the \u201cFuture of Transport.\u201d Three priorities dominated: pedestrian and cyclist safety, traffic volumes, and air quality. Our goal was to develop long\u2011term options aligned with these concerns.<\/p>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;69e199dd0b4bb&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"69e199dd0b4bb\" class=\"wp-block-image size-full wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"352\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/02\/Yogesh1_resized.jpg\" alt=\"\" class=\"wp-image-29472\" srcset=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/02\/Yogesh1_resized.jpg 500w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/02\/Yogesh1_resized-284x200.jpg 284w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\taria-label=\"Enlarge\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.imageButtonRight\"\n\t\t\tdata-wp-style--top=\"state.imageButtonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><figcaption class=\"wp-element-caption\">Traffic at Silver Street showing tight geometry (Source: AtkinsR\u00e9alis)<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-use-a-behaviour-level-model\"><strong>Why Use a Behaviour\u2011Level Model<\/strong><\/h2>\n\n\n\n<p>Space constraints shape every design decision. Bradford-on-Avon offers almost no room for dedicated cycling infrastructure. Footways narrow at busy segments. Several pinch points cannot be widened without heritage impacts. The single river crossing concentrates pressure across the network.<\/p>\n\n\n\n<p>To understand the consequences, we needed behaviour\u2011level microsimulation. PTV Vissim models individual road users and their interactions. It shows how drivers adjust speeds, seek gaps, or yield at narrow sections. It captures multimodal effects that spreadsheets cannot show.<\/p>\n\n\n\n<p>We built a 2023 base model using count data, journey times, bus routes, and crossing surveys. After validation, we generated year 2041 scenarios to ensure long\u2011term resilience.

A bus gate preserved direct bus access. Priority narrowings managed shuttle working, giving uphill traffic precedence. This improved eastbound movement on Mount Pleasant and reduced congestion on Market Street and Silver Street.<\/p>\n\n\n\n<p><strong>Option B<\/strong> also relied on <a href=\"https:\/\/blog.ptvgroup.com\/en\/modeling-planning\/ptv-vissim-traffic-calming-measures\/\" target=\"_blank\" rel=\"noreferrer noopener\">priority narrowings and directional changes<\/a>.

The model showed that the new pressure outweighed gains in other areas.<\/p>\n\n\n\n<p><strong>Option C<\/strong> blended the best parts of both. It avoided major congestion in any direction and produced stable average speeds. Mount Pleasant saw small gains, while Silver Street became more predictable westbound due to its simplified one\u2011way pattern.<\/p>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;69e199dd0c313&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"69e199dd0c313\" class=\"wp-block-image size-full wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"429\" height=\"241\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/02\/Yogesh3_NEWNEW.jpg\" alt=\"\" class=\"wp-image-29468\" srcset=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/02\/Yogesh3_NEWNEW.jpg 429w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/02\/Yogesh3_NEWNEW-320x180.jpg 320w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/02\/Yogesh3_NEWNEW-300x169.jpg 300w\" sizes=\"auto, (max-width: 429px) 100vw, 429px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\taria-label=\"Enlarge\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.imageButtonRight\"\n\t\t\tdata-wp-style--top=\"state.imageButtonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><figcaption class=\"wp-element-caption\">Option A, B, and C layouts.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-environmental-findings\"><strong>Environmental Findings<\/strong><\/h2>\n\n\n\n<p>Traffic and air quality are interconnected.
