ARCADY<\/h1><\/span><\/div><\/div>[vc_column_text]<\/p>\n

Assessment of Roundabout Capacity and Delay<\/h3>\n

Based on three decades of research and development by TRL, ARCADY is used to predict capacities, queues, delays and accident risk at roundabouts. An easy-to-use tool for the busy traffic professional wanting to design new roundabouts and assess the effects of modifying existing sites. Available as a Roundabout module in Junctions 10<\/a>.[\/vc_column_text][\/vc_column][vc_column width=”5\/12″][vc_single_image source=”featured_image” img_size=”large” alignment=”center” css=”.vc_custom_1520349311460{margin-top: -20px !important;margin-bottom: -20px !important;}”][\/vc_column][\/vc_row][vc_row margin_top=”20″ type=”1″][vc_column width=”7\/12″][vc_column_text]Roundabouts are modelled using the well-established TRL\/Kimber capacity relationships (the ARCADY Model<\/a>)<\/span>, which\u00a0<\/span>take into account<\/span>\u00a0key roundabout geometries such as entry width, approach width, flare length, conflict angle, inscribed circle diameter and entry radius. This empirical framework intrinsically links roundabout geometry to driver behaviour and in\u00a0<\/span>turn to predicted capacities, queues and delays.<\/span>\u00a0<\/span><\/p>\n

ARCADY has been successfully used to design and improve\u00a0a number of\u00a0roundabouts throughout the world. It has a host of satisfied customers including governments, multinational organisations and academic institutions. It\u2019s simple and intuitive interface means that it can be used effectively by everyone, in a relatively short space of time.<\/span>\u00a0<\/span>[\/vc_column_text][vc_empty_space height=”16px”][vc_column_text]<\/p>\n
