“…Most V-V merging conflicts occurred in the outbound phase, since outbound vehicle flows tend to concentrate on arterials to leave the area. In relation to V-P conflicts, 8 (12) conflict points spread in 5 (6) intersections during the inbound (outbound) phase. The optimal plan tended to utilize the subshortest routes rather than the shortest ones between source regions and parking lots.…”

During a planned special event (PSE), vehicular and pedestrian movements are concentrated around the PSE venue for short periods, leading to potential conflicts and safety issues. Vehicles tend to park as close as possible to the venue for the convenience of attendees. Taking into account the characteristics of PSE traffic patterns, a strategic vehicle parking planning model is proposed to integrally optimize the assignment of parking lots and inbound/outbound routes around the venue. Two prioritized objectives were considered for traffic safety and for the convenience of attendees. The proposed model was first validated in a small-scale example, and then adopted in a real-world case that took place in Taiyuan, China. The resulting parking plan presented an efficient reduction in the conflict points between vehicular and pedestrian movements, leading to an acceptable average walking distance for attendees. To evaluate the impact of different management preferences on the parking plan, a series of weights for conflict points were set according to potential conflict locations, occurrence times, and types. The results demonstrated that the number of conflict points with higher weights could be effectively reduced by the parking plan.

“…The reliability of a link or segment could vary based on the time-of-the-day. The possibility of capturing extensive, continuous, and dynamic travel time data from private sources such as HERE, INRIX and Tom Tom opened many pragmatic avenues to predict reliability at link-level by time-of-the-day ( 22 , 23 ). BT was observed to be strongly correlated to most travel time performance measures and may be suitable for assessing reliability ( 22 , 23 ).…”

“…The possibility of capturing extensive, continuous, and dynamic travel time data from private sources such as HERE, INRIX and Tom Tom opened many pragmatic avenues to predict reliability at link-level by time-of-the-day ( 22 , 23 ). BT was observed to be strongly correlated to most travel time performance measures and may be suitable for assessing reliability ( 22 , 23 ). As sum of deviations is not the same as deviations of sums, data/measures should be carefully integrated when conducting path-level assessments (not used in the illustrations discussed in this paper).…”

State agencies, regional agencies, cities, towns, and local municipalities design and maintain transportation systems for the benefit of users by improving mobility, reducing travel time, and enhancing safety. Cost–benefit analysis based on travel time savings and the value of reliability helps these agencies in prioritizing transportation projects or when evaluating transportation alternatives. This paper illustrates the use of monetary values of travel time savings and travel time reliability, computed for the state of North Carolina, to help assess the impact of transportation projects or alternatives. The results obtained indicate that, based on the illustration of the effect and impact of various transportation projects or alternatives, both improved travel time and reliability on roads yield significant monetary benefits. However, from cost–benefit analysis, it is observed that greater benefits can be achieved through improved reliability compared with benefits from a decrease in travel time for a given section of road.

“…In the field of traffic engineering, researchers have studied the temporal and spatial impacts of special events on the surrounding traffic system ( 11 – 13 ). In Pulugurtha et al and Sharma et al, a large amount of individual travel data was mined to evaluate the impacts of special events on their travel time ( 11 , 12 ). Wang et al inferred the origin-destination (OD) matrix of bus passengers by combining the data of automatic data collection systems and automatic vehicle location systems ( 13 ).…”

Large-scale activities, holidays, and emergencies often cause a significantly large burst of passenger flow demand in some urban rail transit (URT) stations in a short time, called large passenger flow (LPF). The LPF will propagate through the entire URT network of the city. The impact of the frequent occurrence of LPF on network service levels is crucial and unpredictable. This article describes an analysis of how this LPF propagates through the entire network inspired by how radionuclide imaging is done in clinical medicine. In this study, with LPF of URT as the research object, a propagation model of LPF in URT based on AFC data, train operation data, and URT network topology data was developed, which was inspired by the concept of radionuclide imaging in clinical medicine. In the condition of obtaining the list of passenger route selection ratios, the dynamic propagation state matrix of the LPF in the network is solved. The contribution value matrix of the LPF was proposed to evaluate the impact of the LPF on the URT network. Considering the LPF in Chengdu East Railway Station, China, as an example, the propagation effect of LPF in the Chengdu Metro network was analyzed, and the effectiveness of the proposed model was confirmed.
