Abstract ：
Considering the two measures of information release and congestion charging under uncertain environment，and based on traffic network equilibrium，an optimal toll model of the simple two-route road network is derived and is extended to the general road network. Based on the two-route network，a day-to-day route choice behavior experiment is conducted. The impact of the two measures on travelers’route choice behavior is analyzed. The results show that the implementation of perfect information and congestion charging can both reduce the flow fluctuation，and the effect of congestion charging alone is the best. However，only when the two measures are combined，the trend of road network flow towards user equilibrium is the most stable. Perfect information will increase route switching behavior， while congestion charging can effectively inhibit large route switching. When there is no congestion toll，route switching often increases the travel cost. On the contrary，when congestion toll is implemented，route switching can often reduce the travel cost. The travel time when the two measures of congestion tolling and traffic information release are implemented together is better than that when the two measures are implemented separately. © 2024 Science Press.

Abstract ：
This paper analyzes the utility calculation principle of travelers from the perspective of mental accounting and proposes a travel choice behavior model that considers travel time and cost (MA-TC model). Then, a questionnaire is designed to analyze the results of the travel choice under different decision-making scenarios. Model parameters are estimated using nonlinear regression, and the utility calculation principles are developed under different hypothetical scenarios. Then, new expressions for the utility function under deterministic and risky conditions are presented. For verification, the nonlinear correlation coefficient and hit rate are used to compare the proposed MA-TC model with the other two models: (1) the classical prospect theory with travel time and cost (PT-TC model) and (2) mental accounting based on the original hedonic editing criterion (MA-HE model). The results show that model parameters under deterministic and risky conditions are pretty different. In the deterministic case, travelers have similar sensitivity to the change in gain and loss of travel time and cost. The prediction accuracy of the MA-TC model is 3% lower than the PT-TC model and 6% higher than the MA-HE model. Under risky conditions, travelers are more sensitive to the change in loss than to the change in gain. Additionally, travelers tend to overestimate small probabilities and underestimate high probabilities when losing more than when gaining. The prediction accuracy of the MA-TC model is 2% higher than the PT-TC model and 6% higher than the MA-HE model.

Abstract ：
This paper examines the travelers' day-to-day route-choice behavior with Advanced Traveler Information Systems (ATIS) through laboratory-like experimental method. Five groups of route-choice behavior experiments are designed to simulate actual daily behavior of travelers. In the experiment, subjects are provided with different levels of the complete road network information to simulate the proportion of subjects equipped with ATIS equipment (i.e., ATIS market penetration) and choose the routes repeatedly. The subject's route-choice behavior under different proportions of complete road network information is analyzed, and the strategy of releasing such complete information is determined when the performance of road network system is the best. The Braess network which consists of three routes was used in the experiment and analysis. The results show that the fluctuation of traffic flow runs through the entire experiments, but it tends to converge to user equilibrium. When the market penetration is 75%, both the fluctuation of traffic flow and the tendency of subjects to change routes are the smallest, so the road network system is the most stable. This interesting result indicates that releasing traffic information to all travelers is not the best. Other results show that the travel times of the three routes in the five groups of experiments tend to converge to and finally fluctuate around user-equilibrium travel time. With the increase in ATIS market penetration, the average travel time of subjects in each round tends to increase. The overall trend of the five groups of experiments is that as the number of route switches increases, the average travel time increases. The results also indicate that releasing traffic information to all travelers cannot weaken the Braess Paradox. On the contrary, the more travelers are provided with traffic information, the less likely it will weaken the Braess Paradox.

Abstract ：
This paper presents a reliability-based method for the design of intersection sight distance (ISD) at traffic roundabouts using the linear and nonlinear deceleration profiles of the entry vehicles. The reliability method is based on the first-order second moment method which is simple and relatively accurate compared with advanced methods. The nonlinear deceleration profile includes a shape parameter that produces the linear profile as a special case. Deterministic and reliability-based formulas for the required ISD for an approaching vehicle are developed for the entry vehicle on the left and the vehicle on the circulating roadway. Then, the design values of the ISD legs, applicable to any type of roundabout, are presented for different probabilities of non-compliance (Pnc) and different coefficients of variations. For the special case of single-lane symmetrical roundabouts, which have a well-defined geometry, the lateral clearance needs are established. The sensitivity analysis shows that ISD is very sensitive to both the mean and variance of the critical headway. The results show that the deterministic method results in ISD values that correspond to a very small Pnc, indicating that the method is very conservative. The proposed method, which provides flexibility in selecting ISD for any given Pnc, should be of interest to highway designers and practitioners to promote roundabout safety. © 2020 by the authors.

Abstract ：
基于出行者逐日路径选择过程,建立出行者路径选择模型和逐日路径选择学习模型.在2条平行路径的简单路网中进行多次数值实验,结果表明:网络交通流演化是否稳定,以及能否达到随机用户均衡态,与出行者对昨日感知行程时间的依赖程度和先进的出行者信息系统市场占有率两者都有关系.当出行者对昨日实际行程时间完全依赖时,路网系统始终偏离随机用户均衡态;当出行者对昨日感知行程时间完全依赖时,出行者集中选择一条路径,并且网络交通流演化稳定.

Abstract ：
为了完善现有的交通分配模型,综合考虑出行者的方式选择与路径选择行为,建立了基于分层Logit的多方式随机用户均衡分配模型.首先,在多方式交通网络中,根据出行者出行决策的2个步骤,即首先选择合适的交通出行方式、然后选择该方式交通网络中的出行路径,采用分层Logit模型描述出行者的交通方式和路径联合选择行为.在建立的分层Logit模型中,出行效用与流量分布相互制约,出行效用受路网流量影响,而路网流量由效用所决定,最终要达到平衡.接着,构造了一个数学规划模型来求平衡解,证明数学规划模型的最优解与分层Logit模型的流量解等价,并进一步证明等价数学规划模型的目标函数是凸的,而约束集也是凸的,因此等价数学规划模型是一个凸规划问题,模型的解是唯一的.随后,给出了求解提出的基于分层Logit的多方式随机用户均衡分配模型改进的方向搜索算法步骤.最后,以含公交车和小汽车2种方式的方格形路网为算例,分析公交票价、出行者的时间价值和分层Logit模型的层间比例参数的变化对交通分配结果的影响.结果表明:公交车票价对流量分配的影响不大;公交需求量随出行者时间价值的增加而下降;当出行者的时间价值较低时,公交需求量随分层Logit模型的层间比例参数增加而增加,当出行者的时间价值较高时,公交需求量随分层Logit模型的层间比例参数的增加而减小.

Abstract ：
In this study, the influence of traveler's departure time choice in day-to-day dynamic evolution of traffic flow in a transportation network is investigated. Combining historical information and real-time information, a dynamic evolution model of traffic flow with a study period divided into two intervals is proposed for a simple two-link network. Then, the evolution of network traffic flow is investigated using numerical experiments. Three types of information are considered: (1) only historical information, (2) only real-time information, and (3) both historical and real-time information. The results show that the dynamic evolution of network traffic flow under the three types of information is similar. However, the possibility of chaos occurrence under both historical and real-time information is smaller than that under two individual types of information. When chaos occurs, the chaotic behavior in traffic-flow evolution under only real-time information is relatively less complex than that under the other two types of information.

Abstract ：
This paper proposes a traffic-flow evolutionary model under a dual updating mechanism that describes the day-to-day (DTD) dynamics of traffic flow and travel cost. To illustrate the concept, a simple two-route network is considered. Based on the nonlinear dynamic theory, the equilibrium stability condition of the system is derived and the condition for the division between the bifurcation and chaotic states of the system is determined. The characteristics of the DTD dynamic evolution of network traffic flow are investigated using numerical experiments. The results show that the system is absolutely stable when the sensitivity of travelers toward the route cost parameter (theta) is equal to or less than 0.923. The bifurcation appears in the system when is larger than 0.923. For values of equal to or larger than 4.402, the chaos appears in the evolution of the system. The results also show that with the appearance of chaos, the boundary and interior crises begin to appear in the system when is larger than 6.773 and 10.403, respectively. The evolution of network traffic flow is always stable when the proportion of travelers who do not change the route is 84% or greater.
