The program for designing schemes for the deployment of technical means of traffic management (ODD) performs automated design and development of traffic management projects with the possibility of subsequent editing by an expert (designer). Reporting documents comply with the "Procedure for the development and approval of projects for the organization of traffic on highways" (Moscow, 2006) and other current regulations of the Russian Federation, including the requirements of the traffic police of the Ministry of Internal Affairs of the Russian Federation.
Short description
The program provides for the input, editing and display of all the required elements on the road in accordance with the requirements for the development and execution of TS ODD projects:
- contours of the road plan (crossing and speed lanes, service facilities, bus stop pockets, additional and additional traffic lanes);
- technical means of organizing traffic (traffic signs, road and pedestrian barriers, guiding devices, traffic lights, pedestrian crossings, lighting, bus stops, footpaths, road marking lines);
- railway crossings;
- artificial structures (tunnels, bridges, culverts);
- service objects, assignments and constructions of the road service;
- Engineering equipment and road construction: directories for describing fences, guides, road signs and markings, recreation areas and car parking lots in the database, and much more;
- graphs of longitudinal slopes, plan curves, road marking lines, fences and guides, etc.
In addition to the standard lines provided for by the procedure for developing ODD TS deployment schemes, the following additional lines have been added to the program:
- line with the name of the road and the area of its passage;
- a line that displays the values of the visibility distance of an oncoming vehicle in the forward and reverse directions;
- a line that displays the horizontal visibility distance values in the forward and backward directions.
For lines with visibility distance values, it is possible to set the color highlighting of non-normative values and the ability to manually edit the normative visibility value in the road plan and profile.

Using the module computer-aided design labor productivity increases several times in the development of traffic management projects.
Dislocation schemes are automatically designed on sections of 2-lane highways with the most typical situations:
- on bridges and overpasses;
- on sections of horizontal curves;
- in places where the number of traffic lanes changes;
- exits, intersections and junctions;
- transitional speed lanes and additional traffic lanes;
- bus stops;
- service objects;
- plan and profile elements;
- railway crossings;
- bridges;
- pipes and more.
The automatic design module provides a huge number of settings, for example, for each of the situations you can specify: which signs and at what distance should be installed depending on the category of the road section I, II, III, IV, V; marking length 1.1 and 1.6; the height of the embankment for the installation of fences and guides, the normative value of visibility and much more. Auto-deployment settings can be saved as a file so that it can be used by other users of the program.
In addition to the module for automatic deployment of ODD tools, the program implements tools for quickly placing these objects ( semi-automatic mode):
- Arrangement of designed objects at intersections, junctions, exits;
- Arrangement of designed columns on pipes;
- Arrangement of duplicate signs;
- Placement of markings 1.1 at intersections, junctions, exits;
- Arrangement of signs 2.2 at intersections, junctions, exits;
- Arrangement of signs 2.4 at intersections, junctions, exits;
- Arrangement of the order of signs according to GOST;
- Duplication of actual fences into design ones;
- Duplication of actual sidewalks in design ones;
- Duplication of actual traffic lights into design ones;
- Duplication of actual lighting in design;
- Arrangement of guide devices on: railway crossings; over the real ones;
- Arrangement of kilometer posts (signs 6.13).

The procedure for the development of traffic management projects does not provide for the arrangement of the dimensions of the width of the carriageway and its elements, at the numerous requests of users of the program "Designing schemes for the deployment of vehicles ODD", we have developed an appropriate tool that allows both manual and automatic display of the width of the following elements :
- coverage width;
- the width of the carriageway;
- lane width;
- dividing line width;
- the width of the reinforced part of the curb;
- the width of the speed lane;
- additional lane width.

In the program for designing schemes for the deployment of TS ODD, feedback is provided with the program for development of signs of individual design. This allows:
- store projects of individual design signs in the database;
- change a previously designed sign without having the original project file of this sign on your PC.
Rice. 12 - Window for launching the character editor
The editor of title page templates for traffic management projects has been added to the program, which allows you to:
- create individual cover page templates (information about the name of the road, its boundaries, category, organizations that completed and approved the project are automatically inserted into the templates);
- add any images to the title page (company logos, footers and headers, etc.);
- store the template in the database for use by other users of the program.
An internal editor for templates of explanatory notes for the TS ODD project is built in. This tool allows you to:
- create individual templates of explanatory notes (information about the name of the road, its boundaries, category, organizations that completed and approved the project are automatically inserted into the templates);
- store the template in the database for other users to use.
The setting of the “print script” allows you to create a template for a traffic management project from a set of necessary statements, diagrams, explanatory notes, cover sheets, etc., which will be output to the printer in the specified order and volume.

Based on the results of the design of deployment schemes, all necessary reporting documents are automatically generated: title pages, summary sheets of the scope of work for the installation of signs, fences, guides, artificial lighting, bus stops, pedestrian crossings and paths, traffic lights, etc.
It is often necessary that the program settings be identical on all workstations. To do this, the program has built-in functions for import / export of program settings. This allows:
- reduce the time for setting up the program at the workplace, it is enough to do it on one computer, and on the rest just apply the settings file;
- get absolutely identical settings for displaying objects on the diagrams of the TS ODD and summary sheets;
- if necessary (reinstallation of the operating system, change of workplace, etc.), promptly transfer and restore the program settings.
Rice. 21- Menu for importing and exporting program settings
Program settings deserve special attention. There are more of them in this program than in any other software application of the PC "Titul-2005". This is largely due to the fact that in many regions of the Russian Federation the visual part of the traffic management project is slightly different from the generally accepted one. You can estimate the number of settings in the settings window for displaying road signs and the carriageway, as well as in the settings for the title page of the statements. In addition, for each type of object, the program also provides its own personal parameters: markings, traffic lights, pipes, sidewalks, lighting, etc.

Clause 3.1 of the procedure for developing schemes for the deployment of technical means of road traffic control provides for the possibility of transferring an electronic version of the traffic management project with the possibility of editing them.
In the event that the customer does not have work on designing layouts for the deployment of TS ODD PK "Titul-2005", the program has the ability to export schemes to WMF format (vector graphic format). These files are viewed by standard means of the operating system or using a specialized utility. "Viewing the deployment schemes of the TS ODD"(it is freely available on our website and is installed by default with the main application).
It is possible to edit files of this format using any vector graphics editor (CorelDRAW, Inkscape, Xara Xtreme, etc.)
Export of location schemes is possible both for a given section of a highway and for a network of highways, with automatic distribution of exported files into folders corresponding to the names of highways.

FreeCAD
FreeCAD is an effective growing project, which is a free drafting program in the form of a computer-aided design system, whose task is to fully replace expensive CAD systems. Therefore, designing in FreeCAD will not differ in any way from designing in the above programs.
The program can create three-dimensional models with subsequent automatic creation of two-dimensional drawings of projections of these models. You can import drawings in a large number of formats. There are many drawing tools available.
The program can perform logical operations, export 3D geometry for subsequent high-quality rendering in third-party programs, and the program also supports macros. And at the same time, the program is absolutely free and multiplatform.
DraftSight
DraftSight is another free drafting program that is a professional grade CAD system that stands out from similar programs for its ease of use. This program should be perfect for students who have to draw a lot throughout the learning stage. It can also replace a paid analogue of AutoCAD or KOMPAS-3D.
This drawing program differs from analogues in its ease of use and easy interface.
Judging by the set of tools at the level of AutoCAD, the freeness of the drawing program, and the full support for DWG and DXF drawing formats, one can foresee that the program may become one of the first professional CAD systems.
Our review of drawing programs has come to an end and you will have to choose a program for everyone personally, depending on what you want to get from it in the end, whether the Russian interface of the program and a separate application or a complex solution are important to you. All the engineering programs for drawing presented in the review are good in their own way, so the choice is yours.
A road graph is a digital vector map consisting of topologically connected arcs and nodes, the location and properties of which convey the routes and organization of ground transport with a given accuracy and completeness.
The road graph is created in accordance with the Requirements for Navigation Charts, including a description of classifiers, rules for digital description, data formats, editorial and technical instructions and other documents.
Elements of the road graph are intended for use in tasks of automated routing between any given points on the graph.
The road graph is created based on selected road network objects and is a custom map with arcs and nodes. At the construction stage, the semantic characteristics of arcs and nodes are filled with information about network connectivity and attributes for solving search problems. Arcs can be created in two types - with two-way and one-way movement.
Road graph editing tools are designed to refine the graph in places of multi-level interchanges and form turn prohibitions. The user has the ability to manually delete, add network nodes, replace a two-way arc with a one-way arc, parallelize roads, create arcs and U-turns, and create turn prohibitions at intersections.
The search for the minimum path between points (settlements) is carried out taking into account any characteristics recorded in the arcs of the network (type of roads, speed, number of carriageways). The shortest route can be found either by the minimum path length or by the minimum travel time of the route. When finding the minimum path, it is possible to exclude some arcs, such as emergency sections, from the search. The search results are displayed on the map as an object - a route.
Features of the digital description of the road graph
The graph of roads and road structures is created as a separate user map (layer) without division into nomenclature sheets. The objects describing the road graph constitute a separate layer in the classifier of digital city navigation plans. The road graph contains two main types of objects - arcs and nodes.
Arcs are divided into two types - with two-way and one-way traffic. The arcs of the graph are built, as a rule, along the axial lines of streets, roads and road structures, with the provision of topology at the junction points. One-sided arcs must have the direction of digitization coinciding with the direction of movement along this arc. Arcs with two-way motion can have an arbitrary direction of digitization.
Nodes can sequentially connect two arcs with different characteristics, or connect several arcs at intersections, forks, etc. If the roads physically pass over one piece of terrain at different levels (tunnel, overpass, etc.), then there should be no node at the intersection point of the roads on the graph map. Using a set of one-way and two-way arcs and nodes, it is possible to uniquely describe various types of intersections, single-level and multi-level interchanges. If it is necessary to show a turn prohibition at a crossroads, then at this point the roads can be shown as parallel one-way arcs that have nodes only with those arcs crossing them that are allowed to change lanes.
To simplify the description of turn prohibitions at intersections, the repeated semantics 32821 can be used. An arc that has prohibitions on passing to other arcs (turn prohibitions) must have a list of semantics with code 32821 containing the numbers of arcs to which transition is prohibited. Turn prohibitions are described by the semantics of 32822.
When editing the graph, all allowed crossings at a particular intersection can be displayed in the form of a table of transitions, where the operator marks the allowed or prohibited crossings. After that, the semantics of the arcs are automatically updated.

Automated Road Graph Creation
Mode Building a network performs the creation of a geometric network of arcs and nodes with the simultaneous construction of a logical network. The network is built according to the linear objects selected on the map. Selected point objects will be added to the network as network evils during construction. Selected vector objects can be processed as linear or as points. To create a network, the service.rsc, road10.rsc, road25.rsc classifiers are used, which contain objects: a network node, a network arc, as well as semantics necessary for further work with the network. If the selected linear features have semantics that indicate one-way traffic, then a one-way network can be built. This mode allows you not to create nodes at the intersection of objects that are at different levels (in this case, the objects should not have common metric points).
As a result of construction, a custom map is created containing the following types of objects: a network node and a network arc. All objects of the created map have the obligatory semantics “Network number”. For nodes, a mandatory characteristic is a reference to the arc object to which the node belongs, for arcs, mandatory semantics are the number of the first and last nodes for a given arc and a link to the map object. The user can change the appearance of the created objects by specifying a new classifier and selecting from it the type of nodes and arcs objects. Upon successful completion of the task, a text file of the work log is created. The name of the log file is the same as the name of the user map, but has the LOG extension.
Road Graph Editing
Creating a host. To create a network node, you need to select a network arc and indicate on it the point where you want to create a new node. Semantic characteristics for new objects are entered automatically.
Create a network arc. To create an arc, you need to select a network node and create a line - an arc of the network. If you complete the creation of an arc on an already existing node, then into the semantics of the arc End node number the number of this node will be written. If there is no host within one meter on the map, a new host will be created at the last point of the arc.
Changing the direction of digitization. To change the direction of digitization for the arcs of the network, you need to select an object for editing on the map.
Changing the type of movement. This mode replaces the NETWORK ARC object with the ONE-SIDED NETWORK ARC object and vice versa.
Removing a node from the network. This mode is designed to remove a node from the built network. The node to be deleted must be located at the intersection of four arcs. there will be no common node for all arcs. It is recommended to remove nodes at the intersection of roads with bridges, tunnels, overpasses, etc.
Adding a node to the network. This mode is intended for adding a host to the network. To execute the mode, it is necessary to open a custom map with a constructed network and specify two objects - arcs, at the intersection of which a node will be inserted. The mode of adding a node is the inverse task to the mode of deleting a node, and also extends one arc to another if the distance between them is less than 100 meters on the ground.
Road parallelization. This mode is designed to add parallel sections to the network at road intersections. Parallel sections are added at the intersections of four arcs. If the mode is successfully executed, additional network nodes and one-sided arcs of the network are created. The results of the construction can be used to set turn restrictions. By deleting the nodes in the center of the intersection, it is possible to prohibit turning in one direction or another.
Create ramps and U-turns. This mode is intended for adding ramps and U-turns at road junctions to the network. It is recommended to perform exits and U-turns at intersections for which parallelization was carried out. If the mode is successfully executed, one-sided arc objects are created and the common node is deleted. The results of the construction are applied when determining the minimum routes.
Formation of turn bans. When the mode is activated, it is necessary to indicate in the map the node of the network graph corresponding to the intersection (crossing of roads) with prohibited directions of travel. The formation of prohibitions on turns from one road to another is provided by filling in the semantics Number of forbidden arc in an arc of the network graph. Each arc of the network corresponds to a section of the road between the nodes of the network (crossroads). After selecting a network node, a dialog opens, in the upper part of which there is a diagram of an intersection containing a section of the road network - the selected node, adjacent arcs of the network corresponding to sections of intersecting roads, and numbers of arcs of the network graph. At the bottom of the dialog is a table of no turns. The right column of the table contains the numbers of roads from which the turn will be prohibited. The top line of the table contains the numbers of roads that will be prohibited from turning. The remaining cells of the table contain turn prohibition indicators. Cells in which you can specify the prohibition of U-turn at the selected intersection are marked in gray.
Control and calculations according to the graph
The quality of the created digital navigation maps and city plans is ensured by the quality of the road graph creation, and the collection of data on service objects and road signs, which supplement the description of the road graph with reference information.
The quality of the road graph is determined connectivity all its constituent arcs and nodes (the absence of separate graphs that have no connection with other graphs), accuracy passing graph arcs along the road network, completeness graph (correspondence of the elements of the graph to the current state of paved roads), informative graph elements (the content in the characteristics of the graph of information about the organization of traffic and the existing features and restrictions on each section).
The connectivity of the graph is ensured by the control of the topology of the initial data used to construct the graph, and by the completeness of the account of the available roads in a given territory.
When creating digital navigation charts, it is recommended to create a graph for the entire area of work without dividing it into nomenclature sheets. To create digital navigation charts of smaller scales, the existing graph can be used without changes.
Digital topographic maps can be used as initial data. To ensure the accuracy of the road graph, the road network objects and road structures must first be updated. When updating the objects of the road network and road structures, the control of the topology of objects at the junction points should be performed.
If the graph is created using tracks recorded on GPS receivers, then after collecting all the data on the navigation map (plan), the topology of the graph elements (tracks) at the junction points is monitored.
If the procedure for constructing a road graph creates several graphs for the area of work, then it is recommended to introduce additional sections of the graph using elements of the road and street network (including dirt roads) to ensure the connectivity of the graph elements, if this does not contradict the real state of the terrain (a territory separated by a river , swamps, railways without crossings, etc.).
To ensure the completeness of the graph, the metric of the arcs must correspond to the state of the roads in the year the navigation map was created. The road graph must take into account all asphalt roads (highways and better) outside settlements and all streets in settlements that lead to the specified types of roads. The graph of roads should ensure the laying of a route between all settlements and other industrial and socio-cultural facilities that are actually connected by a road network on the ground. To do this, any available dirt and field roads can be included in the road graph.
To ensure the information content of the graph, it is necessary to fill in the characteristics of the graph with information about the prohibitions of maneuvers (turns and U-turns), information about the speed limit, traffic restrictions and other data provided by the classifier.
The quality of data about service objects is determined by the accuracy of indicating the location of real objects on the ground (and not road signs indicating service objects) and the completeness of information about the purpose and mode of operation.
Road signs with information about traffic features provide visual perception of the navigation map and additional visual control of the graph's correctness. Therefore, the quality of their application is determined by traditional cartographic criteria - the visibility and reliability of the data. Road signs should not overload the map with secondary information. The main features of traffic in individual sections, which can be shown on maps for open use, should be entered in the characteristics of the elements of the graph (arc).
Mode Building a minimal route is designed to determine the shortest distance between two network nodes. To execute the mode, it is necessary to open a custom map with a built network, i.e. on the map there must be network node objects with mandatory semantics: network number and a link to the network arc, and arcs with semantics: the number of the first and last nodes for this arc, a link to the map object and the network number. The minimum route can be built according to distance and time, in the latter case, the arc must have the semantics “Speed”. The construction process is carried out by specifying the start and end points of the route, as well as the construction parameter (length or time). To set the criteria for constructing a minimum route by semantic characteristics, it is necessary to fill in the table "Filter by semantics of arcs". In order to exclude some sections from processing (for example, emergency ones), you need to select the network arcs on the map and set the option Exclude selected objects from construction.
As a result of the mode operation, an object is displayed on the map - the minimum route, the path length is calculated. The actual map objects and the length of the route for each object are recorded in the statistics dialog table. You can select a symbol and record the constructed path as a map object.
Building a distance graph. The distance graph is a set of objects located within certain limits from the specified network node. To build a graph, you must specify the network node and enter a numerical value (length in meters).
As a result of the operation of the mode, arcs located at a distance less than the specified distance from the specified node will be selected on the map.
Mode Building the minimum path between the specified points is designed to determine the minimum path between reference points, provided that each point must be passed once (the start and finish points can be the same). To execute the mode, you need to open a custom map with a built network, i.e. on the map there must be network node objects with mandatory semantics: network number and a link to the network arc, and arcs with semantics: the number of the first and last nodes for this arc, a link to the map object and the network number. GCPs are selected from the map or from a text file. The selection from the map is carried out by pressing the left mouse button, the selection of points is completed by double clicking the left mouse button. To select control points from a test file, you must specify the file name. The file must contain a list of values of the semantic characteristic "Own name" (for example, the list may consist of the names of settlements). When selecting control points from a text file, network node objects must have the semantic characteristic "Own name" (written at the stage of network creation). The minimum route can be built according to distance and time, in the latter case, the arc must have the semantics “Speed”, as well as taking into account semantic characteristics. To set the criteria for constructing a minimum route by semantic characteristics, it is necessary to fill in the table “Filter by semantics of arcs. In order to exclude some sections from processing (for example, emergency ones), you need to select the network arcs on the map and set the Exclude selected objects from construction option.
The result of the work is a table that indicates the order of bypassing the points, the length of the shortest path between the current point and the next, the length of the entire route.
