To meet the objective demands of changing lanes in super-long tunnels adjacent to interchanges

and to solve the problems of lane control and length control in traffic organization

through the analysis of the critical safety status of anti-sideslip and anti-overturning

a model was established based on the minimum headway to calculate the minimum safe distance for lane changes in super-long tunnels or connection sections. Aiming at the requirement of double lane changes for three-lane one-way tunnels and above

in order to ensure a safe distance between front and rear vehicles for lane changes

a probability model was constructed for single and double lane changes to measure the success probability of safe lane changes in connection sections. Aided by the Vissim simulation technology

the analogy analysis of traffic organization methods and lane control methods of super-long tunnels was carried out. Considering the operating safety and traffic efficiency of super-long tunnels

the traffic organization methods could be selected based on the indicators of vehicle delay

lost time

average speed

and the number of lane changes

and the lane control methods could be selected based on the average delay per vehicle

the number of parking times per vehicle

vehicle density

delay ratio

and driving speed. Results show that the minimum distance of connection sections of super-long tunnels adjacent to interchanges should be checked for the minimum distance of safe lane changes

and the success probability of single and double lane changes should be measured based on the safe distance. For the connection sections which cannot meet the length requirements

the traffic organization method that the off-ramp vehicles complete the lane changes in the super-long tunnels is suggested.
