Urban roads should be based on two basic parameters of safety and designed and built the capacity of the vehicle to a speed of safety in the prediction corrtech of transport that is convenient and settled. To this end, and to provide a coordinated and efficient system, it is necessary to consider the structure and possibilities for future cases such as the type of control device parking lots and public transportation systems are considered. corrtech
To increase safety on the roads and intersections of routes and increase the capacity of urban transport networks, there are various methods, corrtech many of which are derived from management. In addition to management of the fact that the number of vehicles is continuously growing, and growing needs and demands increase, creates new facilities corrtech and expansion of existing facilities and the necessary. The facilities, including roads, intersections, parking, and public transportation systems, should be based on certain criteria and specifications and logical design and build.
Urban streets and roads are in two categories: the type of operation, and the geometry, it is evident that there is a close relationship between exploitation and geometric design. Here, the roads are classified based on the type of operation that include: 1. The main distributor roads regional distributor roads 2 3 4 local distributor roads connecting road (access) of a sample an urban network with the aforementioned types of road shows.
Distribution of traffic on the roads is done at relatively long distances corrtech to urban highways and roads can be considered as such. Thus they should be considered in the design and build traffic to various corrtech parts of the city to reach places and other places of the city, they simultaneously. It is evident that the case should be necessary, appropriate exit routes along the main distributor corrtech roads predicted.
Given the role of the road, in most cases will be tried in the geometric design such that they are responsive to the needs and desired goals. As major streets of the road network up to the plan such that the points of intersection collisions have at least Vshybha or other factors affecting the speed and capacity and traffic safety are properly considered and be met.
Tuwaa main distributor roads should be centers corrtech of commercial, corrtech industrial and residential corrtech city with urban roads are connected with each other and can easily access to different parts of the immune are protected. If no city bypass roads for transit traffic, the main distributor roads should be able to properly conduct this type of traffic.
If the main distributor roads with good standards is not possible, to ban other ways such as stopping vehicles on the street, blocking the entrances of branches to reduce the number of intersections and the encounter and the prevention of excursions unnecessary the standard corrtech of the capacity, existing roads to increase.
Of the road, traffic distribution between urban areas (such as residential areas, commercial and industrial), respectively. The road is in fact the main distributor roads to local roads that connect these areas. Regional distributor roads to connect different areas but they often do not continue in the region, as it may be used for transit traffic or the similar role of found Knnh road distribution.
The roads must be designed so that the immunity provided full access to the entire network of urban areas provide. For this reason, it is sometimes necessary measures to prohibit such vehicles to stop at the roadside, or blocking corrtech their end, to be adopted.
In fact, the roads, the roads are small and have little access to buildings and surrounding areas easy. Road connection, such as local distributor roads, residential areas, commercial or industrial Andvdrmhasrh main distributor roads and regions are, and they do not pass. Road traffic is the main distributor and enters corrtech the area of the region and by local roads by road connectivity to homes, in the stores, factories, and institutes of reduce.
Connecting roads also serve as pedestrians are often designed to be a high density of traffic and do not have the necessary vehicles stopped beside them, and the vehicles are crossing of the whole or some of the, in Day or some day, be avoided.
Sometimes the road connecting the deadlock. In such cases, should be sufficient space for circulation at the end of the road vehicles are predicted. A few examples of the ways around Senden vehicles at the end of the impasse is forecast to come in Figure 7-2.
Vehicle speeds in less frequently out of town and could overtake them is limited. Therefore, the practical capacity of urban road capacity Ghalbaaz roads and roads outside of town is less pretty. Plan on urban road capacity corrtech during peak hours, it pours, while in the road outside the city, the average daily traffic volume is desired.
What is the capacity of roads in the city limits, Tqathast why they plan to make good use of the capacity of roads in between them must be carefully and adequately taken into. Two-way road capacity is independent of the distribution of traffic in different directions considered to be
