To study the variation law of driver's sight distance at tunnel entrance and exit, an actual vehicle test was conducted on an expressway in Chongqing (a total length of 160 km, 36 tunnels, including 4 short tunnels, 8 middle tunnels, 14 long tunnels, and 10 extra-long tunnels) in non-peak hours. Eye-tracking data, illuminance, and velocity were collected by eye-tracker, illuminance meter, and non-contact velocimetry with multi-function respectively. Based on the image illuminance extraction method, the illuminance of tunnel entrance and exit were obtained through Matlab. According to the tunnel parameters in reality, the scale model test was designed, and the driving simulation test was carried out to obtain the driver's sight distance at the tunnel entrance and exit. The support vector regression sight distance calculation model was constructed to analyze the relationship among the driver's driving sight distance, velocity, and illuminance to inspect the driver's sight distance at the entrance and exit of the tunnel and put forward some improvement measures.

For the local urban regional traffic with multiple road intersections, the modeling and simulation are carried out in combination with the background of private car commuting, and a private car travel model based on agent cellular automata model is proposed. The effectiveness of the model is verified by analyzing the real traffic scenarios such as recurrence following, acceleration and deceleration, and starting and stopping at traffic lights. The impact of the number of private cars and whether traffic lights are set on the roads on the traffic efficiency of urban areas at multiple intersections is discussed with the average waiting time as the index. The results show that the model can effectively simulate the driving behavior of private cars. The average speed is inversely proportional to the number of private cars and directly proportional to the average waiting time. Setting traffic lights can increase the number of stops. When local traffic flow is not saturated, setting traffic lights will affect traffic efficiency. When local traffic flow is saturated, setting traffic lights can reduce traffic delay and waiting time.

Smart cities play an important role in urban sustainability. However, the impacts on sustainability in multiple dimensions are dynamic at various stages of development. Most of the existing studies have only explored the impact on a single-dimensional sustainability, and the long-term dynamic impact has not been discussed in depth and in quantity. Taking 57 cities in China as examples, this study explores the dynamic impact of smart cities on urban environmental, economic and social sustainability, using the Panel VAR (PVAR) model after performing the unit-root tests, the selection of the optimal lag orders and the Granger causality test. Besides, further discussions on urban agglomerations are made, categorized by population density and geographical locations. The results indicate that ICT has positive effect in early stage but negative impact in the second period on social sustainability. The positive impact of industrial structure on environmental sustainability is strengthened but then weakened. The impact of industrial structure on social sustainability is negative in medium- and high-density cities but positive in low-density cities. Finally, the paper will provide policy recommendations for sustainable development in different periods from the perspective of smartness.

Traffic volume surveys are a key factor in determining the state of road traffic and are a necessary basis for activities such as traffic planning, road construction, traffic control and management and engineering economic analysis. Most traffic volume surveys count vehicles separately by type, so accurate identification of vehicle types is particularly important. This paper is based on traffic volume survey data from eight detection methods for different vehicle types with separate detection counts. Statistical and correlation analyses were carried out separately, culminating in a multiple linear regression model, which yielded specific relationships between the effects of the different models when performing the tests.

Uneven settlement of roadbed and flat scar of wheel are the main diseases of railway vehicles in operation, which have obvious influence on the dynamic response of wheel-rail system and traffic safety. In order to study the influence of two kinds of diseases on traffic safety, a vehicle-track coupling dynamic model was established, and the dynamic response of the vehicle-track system was discussed under the conditions of different settling wavelength, amplitude, speed and length of flat scar. The results show that the impact response of flat scar has great influence on the vertical force of wheel and rail and the load reduction rate of wheel weight, and the amplitude and wavelength of subgrade settlement have great influence on the vertical acceleration of vehicle body. When the train runs at 100km/h, it is recommended that the wavelength of uneven subgrade settlement is greater than 10m, the amplitude is less than 10mm, and the length of flat scar is less than 40mm.

The polymer grouting material (PU) has been increasingly used in trenchless repair of concrete pipes and roadbeds. Investigating the mechanical behavior of the PU-concrete (P-C) contact surfaces provides a basis for further evaluating the stability of the reinforced concrete structures, which, however, has not been conducted yet. In this study, based on the shear testing results, the mechanical properties and cracking characteristics of the P-C contact surfaces were investigated, followed by establishing the damage model. Results show that the cohesion force of the P-C contact surface increases from 0.42 MPa to 1.44 MPa when the density of the PU materials increases, and there exists residual strength when normal stress is applied. The shear failure of the P-C contact surface is caused by the shearing zone, of which the thickness is about 9-10 mm. The theoretical shear stress-strain curves of the P-C contact surfaces are in good agreement with the experimental ones. The maximum relative difference between the theoretical and experimental shear strength is about 4.2%, implying that the damage model can reflect the stress-strain laws of the P-C contact surfaces under shear.

Under the new situation, strengthening architectural design and urban planning and design can effectively improve the effect of urban construction, promote the continuous development of the city and improve the potential value of the design scheme. It is precisely because of this factor that the current research needs to reasonably control the design scheme in combination with the current situation, so as to improve the overall effect of architectural design and effectively enhance the vitality of urban development. From the perspective of risk assessment, this study uses the grey clustering algorithm to verify the scientificity of the method. The experiment shows that the grey clustering method has a good effect on the scientific evaluation of architectural design.

The suburban railway adopts the mode of combined operation of express and local trains, which can solve the problems of uneven temporal and spatial distribution of passenger flow, meet the diversified needs of passengers, improve transportation efficiency and reduce operating costs. By analyzing and summarizing the passenger flow characteristics and transportation demand of suburban railway, aiming at minimizing the total travel time of passengers and enterprise operating cost, a nonlinear optimization model of suburban railway operation scheme is established. Considering the influence factors such as minimum tracking interval constraint and cross-sectional passenger flow constraint and completes the solution of the model by Lingo. The optimization results after running express and local trains show that the total travel time of passengers is reduced by about 97 minutes, and the enterprise operating cost is reduced by 30%, which proves that the proposed model is efficient and feasible.
