A Modeling Framework for Passengers and Freight in Large-Scale Multi-Modal Transport Networks
No full textIn this paper, a modeling framework is proposed to represent the dynamic behavior of both passenger and freight flows in a large-scale multi-modal transportation network. It consists of a macroscopic model developed to support decision makers who intend to utilize the full mobility capacity of a geographical area by allocating the mobility demand on different modes (road and rail transport) or by suggesting multi-modal itineraries. In the proposed modeling framework, the passenger demand allocation on a multi-modal transportation network is obtained by defining and solving an appropriate multi-modal assignment problem

A Discrete-Time Model for Large-Scale Multi-Modal Transport Networks
No full textThe purpose of this paper is to provide a method that can be used to perform resilience analyses on large-scale multi-modal transportation networks. In particular, this work proposes an assignment model through which the allocation of mobility demand on a multimodal transport network is defined at a regional or supra-regional level. The results of the assignment problem are then used as input data of a macroscopic dynamic model specifically developed to represent the dynamics of a multi-modal transport network. Finally, the proposed methodology is applied to represent the behavior of users in the Nguyen-Dupuis test network
High preoperative CEA and systemic inflammation response index (C-SIRI) predict unfavorable survival of resectable colorectal cancer
No full textAbstract Background CEA and systemic inflammation were reported to correlate with proliferation, invasion, and metastasis of colorectal cancer. This study investigated the prognostic significance of the preoperative CEA and systemic inflammation response index (C-SIRI) in patients with resectable colorectal cancer. Methods Two hundred seventeen CRC patients were recruited from Chongqing Medical University, the first affiliated hospital, between January 2015 and December 2017. Baseline characteristics, preoperative CEA level, and peripheral monocyte, neutrophil, and lymphocyte counts were retrospectively reviewed. The optimal cutoff value for SIRI was defined as 1.1, and for CEA, the best cutoff values were 4.1 ng/l and 13.0 ng/l. Patients with low levels of CEA (< 4.1 ng/l) and SIRI (< 1.1) were assigned a value of 0, those with high levels of CEA (≥ 13.0 ng/l) and SIRI (≥ 1.1) were assigned a value of 3, and those with CEA (4.1–13.0 ng/l) and SIRI (≥ 1.1), CEA (≥ 13.0 ng/l), and SIRI (< 1.1) were assigned a value of 2. Those with CEA (< 4.1 ng/l) and SIRI (≥ 1.1) and CEA (4.1–13.0 ng/l) and SIRI (< 1.1) were assigned a value of 1. The prognostic value was assessed based on univariate and multivariate survival analysis. Results Preoperative C-SIRI was statistically correlated with gender, site, stage, CEA, OPNI, NLR, PLR, and MLR. However, no difference was observed between C-SIRI and age, BMI, family history of cancer, adjuvant therapy, and AGR groups. Among these indicators, the correlation between PLR and NLR is the strongest. In addition, high preoperative C-SIRI was significantly correlated with poorer overall survival (OS) (HR: 2.782, 95% CI: 1.630–4.746, P < 0.001) based on univariate survival analysis. Moreover, it remained an independent predictor for OS (HR: 2.563, 95% CI: 1.419–4.628, p = 0.002) in multivariate Cox regression analysis. Conclusion Our study showed that preoperative C-SIRI could serve as a significant prognostic biomarker in patients with resectable colorectal cancer

Simulation Models for the Evaluation of Energy Consumptions of Electric Buses in Different Urban Traffic Scenarios
No full textThe paper presents a methodology to estimate the energy consumptions of a full electric bus in different traffic and operating conditions. Starting from driving cycles, evaluated through a simulation model developed in Aimsun, the Matlab/Simulink energy model of the bus calculates the main electrical and mechanical performance indicators such as the state of charge of the battery as well as power and torque provided by the electric motor. The methodology is applied to a real case study, that is an Italian town in the North of Italy, for which different traffic conditions and drivers' behaviors are analyzed
Traffic-Prediction-Based Optimal Control of Electric and Autonomous Buses
No full textThis letter considers electric and autonomous buses which have to follow a given route, including fixed stops, in extra-urban roads with a given timetable. A charging infrastructure is present in each stop, allowing to charge the bus batteries. An optimal control scheme is proposed in this letter in order to regulate the optimal speed of buses along the route and the stopping/charging times at stops. The proposed control scheme, acting in real time according to a receding-horizon logic, consists of two modules: a traffic prediction model and an optimal control problem solver. The traffic model measures the traffic state in real time, provides the traffic state prediction in the considered road stretch and, in particular, communicates the predicted average speed in each road section to the second module. This latter computes the optimal behavior of buses by optimizing their expected final energy level, by maximizing their compliance with the timetable and by reducing oscillations in the speed profile. Simulation results based on a real case study show the effectiveness of the proposed control scheme
