ODOS 7 overview
ODOS 7 is the latest edition of ODOS road design software. It is a road as well as corridor type facilities (rail lines, airfield runways / taxiways, channels, etc.) design software.
 ODOS 7 introduces direct DWG files reading with automatic recognition of any 3d elements (lines, polylines, 3dfaces, etc.). The exact picture of the DWG file is instantly presented by ODOS, as topographic background for road design. ODOS can fully handle the DWG layers using its own simple controller. During DWG reading, ODOS 7 automatically updates a Digital Terrain Model (DTM) database by all the 3d elements found in the DWG file. Thus, after reading DWG file is completed, ODOS can directly interpolate all 3d elements existing in the file, allowing rapid ground profiles / cross-sections interpolations. In every day use this means that ODOS 7 can directly interpolate DWG files with TIN triangles (3d faces calculated and created by any software), digitized contours, or any combination of those. This new feature makes ODOS 7 a trully open road design software, free of any conversions, special ground formats, special software use or any other user restrictions.
ODOS 7 provides the engineer with intelligent software tools for designing horizontal alignment, vertical alignment, superelevation rates,  pavement widening and cross-sections, intersections and checking in full detail geometric design consistency, safety criteria, stopping / passing sight distance consistency, swept paths, etc. ODOS 7 easily handles the design of a simple road as well as of a complex roadway project with any number of individual roads, at-grade intersections, drainage channels, street networks, etc). Horizontal and Vertical alignment can be created or modified in ODOS 7 using any combination of numerical input and on-screen graphical editing. The initial definition of alignments is tangent based. Any change in any element of the alignment is fully controllable, through the definition of special fixing conditions (e.g. shifting one PI or a curve either connecting with adjacent Pis, or tangential with adjacent curves, changing the direction of a tangent with one or both adjacent arcs fixed, automatic construction of reverse "S" curves with no straight sections, etc.) using compulsory control points (forcing tangents and arcs pass through control points).
Key feature of the ODOS road design software is the interactive real-time 3d design.  Any action taken by the user at any design level automatically affects all the relevant design values. The relationship intelligence incorporated in ODOS complies with the standard road geometric design rules and dependencies. For example a modification in horizontal aligment instantly affects the stationing of several VPIs in vertical alignment, as well as the superelevation rates and possible pavement widenings of the affected curves. All the affected cross-sections as well as the interface lines on plan are automatically updated. This unique feature is operational in ODOS since ODOS 6 version (2001).
The new Greek OMOE-X guidelines (Guidelines for the Design of Highway Facilities - Alignments, based on German RAS-L standards), including the three safety analysis criteria are incorporated in ODOS 7, in order for the system to real-time check in detail the geometric design consistency (over 30 built-in design speed and V85 speed checks of horizontal / vertical alignment and superelevation design values) as well as automatically produce design data deriving from these guidelines (e.g. superelevation rate diagrams, recommended pavement widenings, stopping sight distance envelopes, swept path envelopes, etc.).
ODOS 7 provides the user with a powerful cross-section design organizer, handling the detailed design of all cross-section components (travel lanes, shoulders, pavement / base / sub-base layers, subgrade, frost blanket, cut / fill subassemblies, cut / fill slopes, berms, benches, topsoil stripping, maintaining existing pavement, retaining walls etc.) independent from each other on a link-by-link basis. ODOS 7 allows the user to design Flexible Template Subassemblies (FTS). FTS are fully customizable typical cross-section components, plugged either in median (e.g. raised or depressed median, concrete barrier) or in right / left edge of the pavement (e.g. ditch, curb and gutter), of any shape, dimensions and special design properties (e.g. superelevation / cut / fill slope dependencies, material definitions, etc.). Through FTS, any typical cross-section (rural road, motorway, rail track, runway, tunnel, bridge, etc.) feature can be customized to match in detail any specific components required by the project. ODOS 7 allows the maintenance of a customizable materials library (pavement, base, sub-base materials, gravel fill, concrete, etc.) apart from the standard earthworks materials (excavation, embankment, topsoil stripping, etc.). Any FTS can 'contain' several user defined polygonal boundaries enclosing customisable materials.
Proposed cross-sections are automatically designed by ODOS 7 at any station, as connected series of those components. Cross-section design is dynamic, as ODOS 7 automatically calculates all the necessary design values (road level, superelevation, pavement widening, etc.) and makes intelligent decisions about placing the proper cross-section components, to fit existing conditions.
Earthworks and material quantities are produced automatically by ODOS 7, based on calculated cross-sections.
Complex accurate cross-sections including several roads of the project can be easily produced by the system.
Realistic 3d visualization is available at any stage of the design within ODOS 7 environment.  A powerful drivethrough simulation tool allows the user to accurately check stopping and passing sight distance consistency directly in 3d. For example stopping sight distance consistency check is made as follows. A test car is moving along the road, located at predefined lateral distance and height over the pavement surface, with variable speed, derived by the V85 diagram. An obstacle (e.g. passenger car) is moving at the same direction and predefined relative to centerline position, in front of the test car, at a variable distance equal with the relevant variable required stopping sight distance. The visibility consistency is checked like in real life, simply by viewing from the driver's position the obstacle ahead. If the obstacle is not visible (due to interference of e.g. the ground model or cut slopes of the examined road) then the stopping sight distance is not adequate and corrections have to be made either to the alignment or to the cut slopes). Otherwise visibility check is OK.
ODOS 7 integrates the design capabilities of the road professional with the release of an  innovative fully parametrical automatic at-grade intersection design system. The simple definition of the intersecting roads in the project is enough for ODOS 7 to complete the 3d design of the relevant at-grade intersection. ODOS 7 handles the comprehensive parametric design of six standard T-type and full intersections, according to RAL-K-1 German standards (also in use currently in Greece), allowing for both automatic input of standard values or user definition of the appropriate set of parameters for intersection design such as right and left turn lanes, tapered lane widening, left turn lane definition using queue distance, deceleration distance and tapered lane length, traffic islands, curbs and marginal strips, edge of pavement profiles, pavement lateral slopes, etc. The intersection design consistency according to RAL-K-1 standards (critical values checks) is checked in real-time. Surface drainage is also checked in real-time through continuously updated surface contour lines. Intersection sight lines / visibility areas for stop / accelerate / yield are calculated according to RAL-K-1. Intersection quantities (earthworks and customizable materials) are calculated accurately (volumes defined by ground and intersection surfaces) within the intersection influence area, without the need of cross-sections stationing.
Intersection design in ODOS 7 is fully dynamic. Any adjustment made to any of the roads making up the intersection causes dynamic full rearrangement of the intersection design. This dynamic link between roads in ODOS 7 projects allows for the dynamic design of entire road networks.
Layouts of crossroads, hairpins or curves can be checked against swept paths of design vehicles (passenger car, standard truck, articulated truck, etc.) selected from ODOS 7's library of standard vehicles (compatible with both greek OMOE-X and german RAS-Q standards).
Reports of any results produced by ODOS 7 (earthworks, material quantity estimates, cross section surfaces, stakeout etc.) can be exported in user definable tables in any format (text files, MS-Excel spreadsheets, etc.)
ODOS 7 produces a full set of automatically fully annotated design drawings (plan, profile, superelevation, pavement widening, cross-sections, etc.). ODOS SOFTWARE Ltd. as a member of Open Design Alliance has incorporated OpenDWG technology in all its software products since 2003. ODOS 7 introduces direct DWG files stand-alone exporting, limiting additional CAD usage to simple drafting and plotting commands. Light cheap CAD software (e.g. AutoCAD LT, IntelliCAD) is now more than enough for the drafting work required for the completion of the design drawings made by ODOS 7. Any DWG compatible CAD software (e.g. Microstation) can also be directly used for any CAD processing.
