This paper extends the work of Zhang et al. (2008) to investigate the daily commuting patterns allowing both late arrival in the morning and early departure in the evening in a linear city. Given the fixed parking locations of morning commuters, the Nash equilibrium principle is employed to formulate commuters’ departure time choice in the evening and the user equilibrium principle in terms of daily travel cost is adopted to formulate the departure time choice of morning commuters. A combined regime of linear location-dependent parking fee and time-varying road toll is then proposed to reduce the total social cost (TSC) for the linear city. All the possible equilibrium traffic flows are analytically derived. The analytical results show that (1) commuters, who arrive at work early in the morning, may not depart early in the evening, but their evening trip costs must be lower; (2) when the parking spaces become denser, the evening commute starts earlier and the morning commute starts later; (3) a linear location-dependent parking fee could either advance or postpone the earliest departure time in the morning; (4) three parking modes, distinguished by the order in which commuters park, occur successively as the parking fee rate increases; and (5) an appropriate parking fee can always improve the system efficiency, but no matter how the parking fee is changed, it is impossible to completely eliminate the efficiency loss in the morning. Furthermore, a parking reservation regime joint with time-varying road toll is designed to minimize the TSC for the linear city. Finally, a set of numerical examples are presented to demonstrate the model's properties and these proposed regimes’ performance.

We analyze the commuting patterns and parking modes for integrated daily commuting under different regimes. Based on a bi-direction bottleneck network with a spatial pattern of parking, the daily commuting patterns with parking location choices are analyzed. Without road toll and parking fee, there exist two equilibrium flow patterns and one parking mode. Increasing the parking density would postpone the earliest departure time and shorten the length of departure time period. A linear location-dependent parking fee regime without road toll is then proposed. We find that three parking modes occur across the parking fee rate and the morning efficiency loss always exists no matter how the fee rate is changed. Furthermore, a combined regime of linear location-dependent parking fee and time-varying road toll is developed to minimize the total daily social cost (TDSC). Two parking modes occur as the parking fee rate increases and there exist four equilibrium flow patterns. We show that the linear location-dependent parking fees could either advance or postpone the earliest morning departure time. An inappropriate parking fee rate may increase both individual and social costs. The best system performance can be achieved with joint consideration of both the TDSC and parking supply cost.

The bottleneck model introduced by Vickrey in 1969 has been recognized as a benchmark representation of the peak-period traffic congestion due to its ability to capture the essence of congestion dynamics in a simple and tractable way. This paper aims to provide a 50th anniversary review of the bottleneck model research since its inception. A bibliometric analysis approach is adopted for identifying the distribution of all journal publications, influential papers, top contributing authors, and leading topics in the past half century. The literature is classified according to recurring themes into travel behavior analysis, demand-side strategies, supply-side strategies, and joint strategies of demand and supply sides. For each theme, typical extended models developed to date are surveyed. Some potential directions for further studies are discussed.

High-occupancy vehicle (HOV) lane has been designed to maximize the movement of people rather than vehicles. For completely understanding the travel pattern of a multilane highway system, this paper presents a dynamic user equilibrium framework, in which commuters, composed of solo-driving drivers, ridesharing drivers and ridesharing passengers, choose their departure times and transport modes to workplace every day. The ridesharing vehicles can use both the HOV lane and the general purpose lane while the solo drivers are only allowed to use the latter. It is found that the rush hour on both lanes is identical but the system’s total travel cost decreases, in a nonlinear way, with the expansion of HOV lane’s capacity.

Metropolises in emerging markets are facing serious urban transport challenges. Understanding people’s travel preferences is crucial for designing effective sustainable urban policies. Little attention has been paid to studying travel preferences in multimodal transport systems in these markets. This study estimates the travel preferences in the metropolitan area of Beijing, which is notoriously plagued with high degrees of congestion. We administered a series of interwoven stated preference experiments on travel behavior. A semi-random sample of 2652 respondents participated in the experiments. The data were pooled and a scaled mixed logit model was used for estimation. The results provide rich information on how trade-offs are made among the manipulated attributes regarding travel time, cost, convenience, and reliability. Many findings deviate from results obtained in developed countries. A contrast standing out is that travelers in Beijing place much less weight on possible delays caused by traffic congestion.

This paper analyzes the political feasibility of road pricing. In a monocentric city, we assume that every morning, there are a fixed number of commuters going to work by car or by bus. A flat toll is levied on commuters who drive to work and the toll revenues are redistributed to all commuters or bus riders only, or not at all. If more than half commuters support or benefit from the pricing scheme, it is considered politically feasible, and vice versa. We show that no one supports implementing road pricing if the toll revenues are not returned, and that the two revenue redistribution measures can produce the identical modal split and departure pattern, but their politically feasible toll intervals are different. Furthermore, if commuters without cars are the majority, they will benefit from the pricing scheme while commuters with cars suffer, regardless of the redistribution measures. However, all commuters may benefit from the pricing scheme when commuters with cars account for an overwhelming majority. This research provides a method for the government to evaluate under what conditions implementing road pricing is politically feasible.

With the rapid development of economy and society, the urbanization process is speeding up in China. Thereupon, several large-size urban agglomerations (or city groups) have emerged. In the present China, a typical city group consists of more than three cities, which are 50–250 km apart from each other, closedly connected in social and economic activities but administratively belonging to different provinces, and each has a population of over five million. It has become an enormous challenge to develop a comprehensive modern transportation system to serve the intercity and intracity traffic effectively, smoothly and eco-friendly. This article presents representative research progress in developing and operating such systems, with consideration of the state condition in China. The following topics, but not limited to, are addressed: (1) Travel behavior analysis and demand integration management within a city group; (2) Agglomeration system design and operation management; (3) Risk identification and emergency management of the agglomeration system; (4) Sustainable development issues.

The bathtub model provides a vital analysis tool to capture the features of traffic jam, especially that of hypercongested traffic. For reducing the complication of analysis, previous studies adopted the constant α-β-γ preferences for travel time, arrival early and late penalties. This treatment not only destroys the continuity of user equilibrium (UE) departure rate, but also leaves out of considering the influences of continuity of schedule preference. In this paper, we investigate a specific bathtub model with continuous schedule preference (CSP) and explore the UE and social optimum (SO) solutions. Analytical and numerical results show that the introduction of CSP lets departure rate continuous. In the UE state, it results in traffic congestion being more costly and duration of hypercongestion being longer than existing bathtub models. In the SO state, the system cost becomes lower. Our study extends the knowledge about bathtub models and provides more insight into downtown traffic congestion.

In this paper, we analyze the optimal capacity allocation for high occupancy vehicle (HOV) lane in morning commute, using the classical bottleneck model to a single corridor. The vehicular traffics are divided as high occupancy vehicle (HOV) and low occupancy vehicle (LOV) based on the number of in-vehicle travelers. The whole corridor is allocated as general purpose (GP) lane and HOV lane, separately with a bottleneck at the end of each lane. The optimal capacity of HOV lane for minimizing the system’s total cost is analytically derived. It is found that with optimal capacity of HOV lane, each HOV traveler experiences lower cost than each LOV traveler. Numerical examples are presented to verify all analytical results.

The concept of resilience can be realized in natural and engineering systems, representing the ability of a system to adapt and recover from various disturbances. Although resilience is a critical property needed for understanding and managing the risks and collapses of transportation systems, an accepted and useful definition of resilience for urban traffic as well as its statistical property under perturbations are still missing. Here, we define city traffic resilience based on the spatiotemporal clusters of congestion in real traffic and find that the resilience follows a scale-free distribution in 2D city road networks and 1D highways with different exponents but similar exponents on different days and in different cities. The traffic resilience is also revealed to have a scaling relation between the cluster size of the spatiotemporal jam and its recovery duration independent of microscopic details. Our findings of universal traffic resilience can provide an indication toward better understanding and designing of these complex engineering systems under internal and external disturbances.

We propose a dynamic tradable credit scheme for control of the day-to-day evolution process of traffic flows towards the system optimum (SO) state in a traffic network with elastic demand. In the scheme, the distribution and charge of travel credits are adjusted from period to period. The interacting dynamics among day-to-day traffic flows, period-to-period credit adjustment, and day-to-day credit price is formulated as an evolutionary game model. We mathematically prove two properties of the model, i.e., the consistence of the stationary state with the SO state and the convergence of the evolutionary trajectory. Finally, numerical results on a middle-size network are presented to validate the dynamic tradable credit scheme and to demonstrate the properties and application of the model.

With the extensive use of smart-phone applications and online payment systems, more travelers choose to participate in ridesharing activities. In this paper, a multi-modal route choice model is proposed by incorporating ridesharing and public transit in a single-origin-destination (OD)-pair network. Due to the presence of ridesharing, travelers not only choose routes (including main road and side road), but also decide travel modes (including solo driver, ridesharing driver, ridesharing passenger, and transit passenger) to minimize travelers’ generalized travel cost (not their actual travel cost due to the existence of car capacity constraints). The proposed model is expressed as an equivalent complementarity problem. Finally, the impacts of key factors on ridesharing behavior in numerical examples are discussed. The equilibrium results show that passengers’ rewards and toll charge of solo drivers on main road significantly affect the travelers’ route and mode choice behavior, and an increase of passengers’ rewards (toll) motivates (forces) more travelers to take environmentally friendly travel modes.

With the improvement of urban smart level, parking reservation has become not only one of the most effective ways to solve parking problems but also an efficient tool to reduce traffic congestion in eliminating the cruising. This paper proposes a new dynamic pricing model for parking reservation, aiming to maximize the expected revenue of the parking manager. The parking requests arrive as a Poisson process, and the arrival intensity is influenced by the time-varying parking price. The optimal pricing scheme is proved to be unique for any general demand and derived in closed form for some particular types of demand functions, like exponential and linear. Numerical examples show that the dynamic pricing scheme can provide significant improvement in revenue and make full use of the parking resources during peak periods.

The submicron copper particles with a mean diameter of 197 nm were obtained using lactic acid as stabilizer and sodium hypophosphite as a mild reducing agent. The obtained Cu particles show a good oxidation resistance owing to the weak reducibility of lactic acid. The screen printable copper ink with a metal loading of 50 wt.% was prepared using the obtained copper particles. The copper films after sintering at 150 °C for 1 h in nitrogen atmosphere exhibit a relatively low resistivity of 1.87 × 10 -4 Ω·m. The conductive copper film circuits were successfully fabricated on flexible polyimide (PI) substrate, with which an LED can be lighted up easily.

Silver nanoparticles (Ag-NPs) with the average size of 9 nm and tin nanoparticles (Sn-NPs) with the average size of 30 nm were synthesized via chemical reduction in aqueous solutions, respectively. Then, a novel nano-sliver paste modified by tin nanoparticles (NSP-TNP) was developed and the influences of Sn-NPs content, sintering time and temperature on bonding strength of NSP-TNP joints were studied. After sintering the nano-silver paste modified by 3 wt.% Sn-NPs at 206 °C for 30 min without externally applied pressure, the bonding strength of sintered NSP-TNP joints reaches 34 MPa. The enhanced mechanical strength of the sintered NSP-TNP joints is owing to the denser structure and solid-solution strengthening when Sn-NPs were added to the nano-silver paste. The NSP-TNP is promising to be used in power semiconductor (e.g., SiC) packaging due to some advantages such as higher bonding strength, lower processing temperature and reduced cost.

The objective of this paper is to provide new insights into commuters’ mode choice behavior in a monocentric closed city with endogenous population distribution, where a congested highway and a crowded railway provide commuting services for residents on a linear urban corridor. We first explore the typical equilibrium mode-choice patterns with exogenous city boundary and population distribution, and then incorporate the residents’ mode choice into an urban spatial equilibrium model, in which the residents’ household consumption, the residential location choice and the property developers’ housing production are also explicitly modeled. Using comparative static analysis, we find that the urban corridor expands with the increase of railway fare if there is no congestion in the bimodal transportation system, but it’s not necessarily the case if highway congestion and transit crowding cannot be ignored. We provide numerical evidence to show that the urban corridor possibly shrinks with the increase of railway fare once congestion effects are considered. We also discuss the changes of urban form, utility level of residents and social welfare with different railway fare and subsidy policies. Numerical results show that the distance-based fare policy with low subsidy should be preferred because it can realize the Pareto-improved social welfare and utility level of residents.

The dynamic traffic equilibrium problem has been a pivotal area of research in transportation for a few decades. The current state-of-the-art research in this area generally considers simultaneous departure time and route choice. In this paper, we theoretically prove that, in the simplest standard bottleneck model with a sufficient number of commuters, a dynamic user equilibrium (DUE) cannot be reached through a day-to-day evolution process of travelers’ departure rate—a central idea behind the iterative dynamic traffic equilibrium algorithms prevalent in the literature. We carry out our exploration with the proportional swap system and then extend our analysis to other typical dynamic equilibrium algorithms such as the network tatonnement process, the simplex gravity flow dynamics, the projected dynamical system, and the evolutionary traffic dynamics. Our investigation indicates that any algorithm analogous to the five categories of systems must be cautious in terms of convergence when it is applied to solve the DUE problem with a departure time choice, and hence puts forward a general question: Are we really solving the DUE problem with a departure time choice?
