Composition of project documentation for the construction (reconstruction) of highways. Evaluation of project solutions based on indicators of speed, traffic safety and throughput. Characteristic features of expressways. Sketch design. Stages of development of pre-project documentation for construction. The main goals and objectives of the engineering project. Matching the road with the landscape. The importance of road landscaping tasks. The composition of the description of road conditions, organization and safety of road traffic. Criteria for choosing a rational option for a road.
Road quality assessment. The value of the estimated speed of movement during project development. Combined evaluation methods that allow evaluating the road both as an engineering structure and as an engineering and transport structure. Formation of the full volume of input information regarding the operational parameters of the road for a field survey.
Determination of parameters of transport flows. Determination of the intensity of traffic flows. Irregularity of traffic flows over time. The composition of the traffic flow. Type of vehicle and its characteristics. Recommendations for choosing the values of the conversion factor of any type of vehicle to a passenger car. Determination of the speed of traffic flow. Informing drivers about speed limits. Limiting speeds of cars. Assessment of the security of the estimated speed. Conditions of the road surface. The maximum speed of movement on sections with different traffic conditions.
