The first traffic bottleneck model for analyzing travel behavior at traffic bottlenecks was proposed by Vickrey [1]. Based on Vickrey’s traffic bottleneck model, many researchers have conducted extensive research on travel behavior at traffic bottlenecks. Guo et al. [12] studied the daily departure time choice behaviors of commuters with a congestion model, accounting for the bounded rationality of travelers. Chen et al. [13] studied an early peak commuting problem with bottleneck settings, where the bottleneck capacity varied with queue length. Li and Huang [14] explored the user equilibrium state of single-entry transportation corridors and proposed a new mathematical model considering travelers’ preferences for specific departure times. Frascaria et al. [15] studied the emergence of super-congestion in Vickrey bottleneck networks, and the departure time of travelers was determined by the second price auction mechanism. They analyzed the conditions for the occurrence of super-congestion and discussed possible policy interventions to prevent congestion. Chen et al. [16] proposed a new modeling framework that combines Vickrey theory with macroscopic data to analyze traffic dynamics in a transportation network from the outskirts of the city to the city center. In the above models, it is assumed that the time value cost and ideal time to reach the work area (or ideal time to pass through a bottleneck) are the same for all travelers.

To make the bottleneck model more realistic, many researchers have improved and extended the classic bottleneck model by considering heterogeneous travelers (i.e., different travelers have different time value costs and ideal times to pass through a bottleneck). Liu et al. [2] proposed a semi-analytical method to solve bottleneck models with general user heterogeneity. They used a dichotomy method to decompose the problem into multiple linear subproblems and then used matrix decomposition techniques to solve these subproblems, ultimately obtaining a closed analytical expression. Lamotte and Geroliminis [17] considered the problem of morning peak congestion for travelers with different travel distances in urban areas. They proposed a new mixed flow model to describe this heterogeneity, where travel time and residence time are set based on different travel distances and destinations, respectively. Qian and Zhang [18] regarded user heterogeneity as a parameter with a continuous distribution and incorporated it into the general equilibrium theory framework. They proposed a solution method that expresses the equilibrium conditions as a set of nonlinear integral equations based on optimal decision making and solved them using an iterative algorithm. Akamatsu et al. [19] recently proposed a new departure time selection equilibrium model that considers user heterogeneity and incomplete information.

Some researchers have constructed corresponding bottleneck models considering random demand, while others have constructed corresponding theoretical models for Y-type bottlenecks, capacity decline, and other situations [20,21,22]. The classic bottleneck model only considers activities from residential to work areas, and some researchers have extended the classic model by considering the travel chain [23,24]. With the development of autonomous vehicles, some researchers have proposed corresponding bottleneck models for autonomous vehicles. Zhao, Y. et al. [25] investigated the impact of autonomous vehicles on commute ridesharing, particularly considering uncertain work end times. This study explored potential changes in commuting dynamics with the introduction of autonomous vehicles. Su, Q. et al. [26] addressed the morning commute problem in the era of autonomous vehicles, focusing on distant parking options. This research delved into how autonomous vehicles may influence commuting patterns and parking choices. Zhang, X. et al. [27] examined the equilibrium analysis of morning commuting and parking in the context of spatial capacity allocation within an autonomous vehicle environment. This study aims to understand the implications of autonomous vehicles on commuting behaviors and parking dynamics. Yu, X. et al. [28] explored the relationship between autonomous cars and the activity-based bottleneck model. They investigated how in-vehicle activities contribute to shaping aggregate travel patterns, providing insights into the interaction between autonomous technology and travel behavior. Lu, G. et al. [29] focused on trajectory-based traffic management within an autonomous vehicle zone. This research delved into methods for effectively managing traffic patterns in areas where autonomous vehicles are prevalent, with an emphasis on trajectory-based approaches. Additionally, researchers have considered the effects of transportation mode choice and activities on travelers and studied travel choice behaviors based on bottleneck models [30,31].

In terms of traffic bottleneck management, the most studied area is congestion pricing for traffic bottlenecks. The development of congestion pricing models is closely related to the development of traffic bottleneck models. The initial congestion pricing models for commuting corridors were based on bottleneck models that considered homogeneous travelers, such as Vickrey’s [32] application of queuing theory to consider the effect of time-varying fees on bottleneck travel efficiency. Based on Vickrey’s research, many researchers have conducted extended research on congestion pricing strategies for bottlenecks. Xiao et al. [33] studied the effect of implementing affordable pricing and strategic waiting schemes for toll roads during morning peak commuting.

With the development of bottleneck models considering heterogeneous travelers, many researchers have studied static (fixed fees) and dynamic (different charging standards for different time intervals) pricing strategies based on the consideration of heterogeneous travelers [34,35]. A small number of researchers have studied bottleneck pricing strategies considering random demand [36,37,38], while others have studied corresponding pricing strategies by considering travel chains and constructing bottleneck models based on activities [39,40]. In addition, many researchers have conducted extended research on and explored applications involving congestion pricing, such as bottleneck control strategies based on road tickets and charging strategies for travel mode adjustment [41,42,43,44].

Although congestion charging has attracted the most attention from researchers, it cannot be effectively implemented in many countries and regions due to its unfairness and low acceptance among travelers. Therefore, many researchers have studied traffic bottleneck control strategies from other perspectives, such as carpooling behavior and parking restrictions. Xiao, L. et al. [45] delved into the dynamics of carpooling behavior within the morning commute problem, particularly when facing constraints on parking space. Their focus is on optimizing commuting solutions in scenarios with limited parking availability. Xiao, L. et al. [46] examined the temporal and spatial allocation of bottleneck capacity in the context of managing the morning commute with carpooling. Their aim was to improve overall efficiency through a strategic allocation approach. Fu, Y. et al. [47] addressed the issue of parking management during the morning commute, specifically in the context of ridesharing. They explored how effective parking resource management can enhance the entire morning commute experience. Zhong, L. et al. [48] investigated dynamic carpooling during the morning commute, shedding light on the significance of high-occupancy-vehicle (HOV) and high-occupancy-toll (HOT) lanes. They analyzed the impact of these elements on shaping carpooling behaviors. Liu and Li [49] contributed to the discourse by exploring the design of pricing schemes for ridesharing programs addressing the morning commute problem. Their focus was on devising pricing strategies that establish a fair and effective system. Wang, J. et al. [50] introduced a dynamic ridesharing scheme, proposing a variable-ratio charging–compensation approach for the morning commute. Their contribution lies in aiming to enhance the appeal of ridesharing through the implementation of flexible pricing mechanisms. Ma and Zhang [51] delved into the morning commute problem, considering both ridesharing and dynamic parking charges. Their contribution involves exploring the dynamic adjustment of ridesharing and parking charges to optimize the overall commuting experience. In addition, some researchers studied control strategies considering parking charges and parking capacity restrictions [52], the optimization of working hours [10], travel chains [53,54], speed limits [11], and other measures. A small number of researchers have also studied the effect of incentive strategies on traffic bottleneck management [55].

Blockchain technology was invented by Satoshi Nakamoto in 2008 as a public ledger [56] for Bitcoin transactions. In an environment that is not completely trusted, it can be used to verify and store data by building a peer-to-peer network using a chained data structure. The blockchain structure is determined by a distributed consensus mechanism to ensure the security of data transmission and access through cryptography. Data can be uploaded and accessed by using a smart contract composed of automated script code. Thus, this technology is based on a brand-new distributed infrastructure and computing paradigm. Its inherent characteristics of transparency, trustworthiness, tamper resistance, traceability, and high reliability give it unique advantages in data authentication, storage, privacy protection, and tokenization. Additionally, blockchain technology is not a single information technology. It can reconfigure and develop existing technologies to create new application functionalities. The many advantages and characteristics of this technology indicate that it can theoretically meet the requirements of interconnectivity, safety, and efficiency in the sharing and management of transportation and travel information.

At present, blockchain technology has received research attention from many researchers and enterprises in the fields of supply chains, public management, logistics, and transportation. Sensen et al. [57] proposed a solution for an organic agriculture supply chain framework based on blockchain and edge computing technology, aiming to solve the trust crisis. Yu et al. [58] proposed a solution for the quality control system of a green composite wind turbine blade supply chain based on blockchain technology. Zhang et al. [59] studied the effect of digital transformation based on blockchain technology on the cold supply chain of third-party logistics service providers. Zhong et al. [60] explored the effect of product information traceability in a dual-channel supply chain based on blockchain technology under government subsidies. Dong et al. [61] considered the phenomenon of green washing and the effect of blockchain technology on logistics outsourcing. Wang et al. [62] studied the effect of blockchain technology on port logistics capabilities, focusing on two different application methods: exclusivity and sharing. Li et al. [63] considered the application of blockchain technology in sustainable supply chains, with a focus on fairness and green investment.

Research on the application of blockchain technology in traffic congestion management is still lacking, often only consisting of a framework description [64,65] and lacking application analyses to solve specific problems.
