Urban rail transit has a large transport capacity due to the high density operation, short train running time interval, high running speed and large number of train units. One-way peak transport capacity of up to 60,000 to 80,000 passengers per hour (suburban railway); The number of subway passengers reached 30,000 to 60,000, and even 80,000; Light rail 10,000 to 30,000 people, trams can reach 10,000 people, the transport capacity of urban rail transit far exceeds that of buses. According to literature statistics, the annual passenger volume of underground railway per kilometer line can reach more than 1 million people, up to 12 million people, such as Moscow subway, Tokyo subway, Beijing subway and so on. Urban rail transit can transport large passenger flow in a short period of time. According to statistics, the subway can pass 17% ~ 20% of the daily passenger flow in 1h and 31% of the daily passenger flow in 3h in the morning peak.
punctuality
Urban rail transit is an all-weather means of transportation because it runs on the dedicated carriageway, is not interfered by other means of transportation, does not produce line blockage phenomenon and is not affected by climate, and the train can run according to the train chart, with reliable punctuality.
Speed of access
Compared with conventional public transportation, urban rail transit, because it runs on the dedicated lane, is not interfered by other means of transportation, vehicles have higher running speed, higher start and brake acceleration, most of them use high platforms, train stop time is short, quick and convenient to get on and off the train, and convenient transfer, so that passengers can reach the destination faster and shorten the travel time.
comfort
Compared with conventional public transport, because urban rail transit runs on lines that are not interfered by other means of transport, urban rail vehicles have better operating characteristics. Vehicles and stations are equipped with air conditioning, guidance devices, automatic ticket sales and other equipment directly serving passengers. Urban rail transit has better riding conditions and its comfort is better than that of public trams and buses.
security
Because urban rail transit is running on a dedicated track, there is no level crossing, it is not interfered by other means of transportation, and it has advanced communication signal equipment, and few traffic accidents occur.
Space utilization
Land in big cities is crowded and expensive. Because urban rail transit makes full use of the development of underground and above-ground space, without occupying surface streets, it can effectively alleviate the road congestion and blockage caused by the massive development of automobiles, which is conducive to the rational utilization of urban space, especially to alleviate the overcrowding in the central area of big cities, improve the value of land use, and improve the urban landscape.
Low cost
Urban rail transit mainly uses electric traction, and wheel-rail friction resistance is small, compared with public trams, buses save energy and lower operating costs.
Lower pollution
Urban rail transit, due to the use of electric traction, does not produce exhaust pollution compared with buses. Due to the development of urban rail transit, the number of buses can also be reduced, further reducing the exhaust gas pollution of cars. Due to the adoption of various noise reduction measures on the lines and vehicles, there is generally no serious noise pollution to the urban environment.
