A serious highway accident with long duration will lead to a great delay. If the extended travel time is beyond travelers' tolerance, they will make a detour by choosing any other roads. However, the driver's behavior of taking other routes will make an impact on the surrounding road network. Thus that impact is called the indirect impact by highway traffic accidents in road network. The range of...
Due to the static traffic assignment not describing the dynamic traffic flow of network, and as the intelligent traffic developing, dynamic traffic assignment becomes research hotspot. Traffic control strategy will influence the driver's route choices, so these effects should reflect in the dynamic traffic assignment. Freeway traffic bottleneck section or accident often forms different degree of congestion,...
The vehicles of on-ramp junction need to import or separate rapidly, and they will generate disruption to the straight vehicles. The result is the influence to the traffic capacity of mainline and entrance ramp when the accident takes place on the convergence. This paper mainly studies the traffic capacity of entrance ramp and adjoining mainline when the accident happens inside and outside the convergence...
According to the importance of loop freeway and the marked interference of the traffic accident of fog loop freeway to traffic flow, based on network, propose the emergency traffic organization in the influence region which includes protection, control and buffer in this paper. Through collecting traffic accident interference data of Xi'an loop freeway, firstly calculate maximum queue length of buffer...
A biological contact oxidation reactor (BCOR) was set up behind demand aeration tank/intermittent aeration tank (DAT/TAT). The removal effect of ammonia nitrogen (NH3-N) from domestic wastewater in the combined process was investigated. The results show that when the operating periods of IAT are set at two hours for aeration, one hour for sedimentation, one hour for effluent, and HRT of the BCOR is...
