Method for setting freeway service facility intervals in high attitude area

Abstract

The invention belongs to the field of freeway service facility design and discloses a method for setting freeway service facility intervals in a high attitude area. The method comprises the steps of establishing a driver fatigue model; determining initial fatigue intervals and deep fatigue intervals; determining an initial interval range of service facilities of a second type; obtaining a vehicle oiling request, correcting the initial interval range of the service facilities of the second type, and obtaining a final interval range of the service facilities of the second type; determining an initial interval range of service facilities of a third type; obtaining drivers' requirements of going to the toilet and truck requirements, correcting the initial interval range of the service facilities of the third type, and obtaining the corrected interval range of the service facilities of the third type; and determining a final interval range of service facilities of a first type and a final interval range of the service facilities of the third type according to the final interval range of the service facilities of the second type and the corrected interval range of the service facilities of the third type, so that the service facilities in the high attitude area can genuinely meet the traffic operation requirements.

Description

technical field [0001] The invention relates to the field of expressway service facility design, in particular to a method for setting intervals of expressway service facilities in high-altitude areas, which can be used for setting intervals of expressway service facilities in high-altitude areas with an altitude of 2000 meters to 6000 meters. Background technique [0002] The high-altitude areas in western my country are extremely cold, low-pressure, and hypoxic. There are sparsely populated areas along the route, and the distribution of cities and towns is scattered. On the one hand, with the rapid development of my country's economic construction, the country has proposed the construction policy of "one road and one belt", and the difficulty of expressway construction in permafrost areas has also been gradually overcome; on the other hand, the section from Golmud to Lhasa is the capital of the seven national "7918" network An important section of the radiation line, but co...

AI Technical Summary

Problems solved by technology

It stipulates that service areas should be set up on expressways, and the average interval should be 50km. When the distribution of cities and towns along the line is sparse and the supply of water and electricity is difficult, the distance between service areas can be increased, but there is no clear regulation on how much to increase.

If the interval between its service areas is fully implemented in accordance with the current national standards, the construction cost will be greatly increased, and after completion, due to the high cost of manpower and material resources in high-altitude areas, some service areas may even be unused, resulting in waste of resources , but on the other hand, the oxygen content in this area is low and the transportation mileage is long. Compared with the plain area, the driver is more prone to fatigue. If the interval is set too long, traffic accidents caused by fatigue may occur

[0004] In addition, the vast majority of published articles on the interval setting of service areas are about low-altitude areas. Due to the particularity of the Qinghai-Tibet Plateau, there are few related articles at home and abroad that involve the interval setting of service facilities in high-altitude areas. patent
