On the one hand, travel time is important in planning and managing urban roads; on the other hand, it is important in commuters' route and departure time decisions. Often, mode and route choices and a sense of departure time are mainly based on one’s perceived travel time (PTT). This study focuses on modelling travellers’ PTT considering socio-economic and trip attributes for an urban corridor, taking Surat as a case study. An ANOVA test has been conducted to identify factors governing PTT. Analysis shows that trip attributes (e.g., traffic conditions, traffic environment, and travel distance) influence PTT more than travellers' socio-economic characteristics (e.g., income, occupation, age, and vehicle ownership). Commuters overestimate PTT (min/km) nearly two-fold, and the overestimation decreases with increasing trip distance. A PTT Estimation Model has been developed using Fuzzy Logic, considering the epistemic uncertainty associated with attributes. The developed model can help inform necessary improvement measures to bring travel times to a reasonable level.
一方面，旅行时间对城市道路的规划和管理非常重要；另一方面，旅行时间对乘客的路线和出发时间决策也非常重要。通常情况下，出行方式和路线的选择以及对出发时间的感知主要基于个人的感知旅行时间（PTT）。本研究以苏拉特市为例，重点研究了考虑到社会经济和出行属性的城市走廊乘客感知旅行时间模型。通过方差分析测试来确定影响 PTT 的因素。分析表明，出行属性（如交通状况、交通环境和出行距离）对公共交通时间的影响大于乘客的社会经济特征（如收入、职业、年龄和车辆拥有量）。通勤者高估了近两倍的公共交通时间（分钟/公里），而且高估的程度随着旅行距离的增加而降低。考虑到与属性相关的认识不确定性，我们利用模糊逻辑建立了一个公共交通时间估算模型。所开发的模型有助于为必要的改进措施提供依据，从而将旅行时间控制在合理水平。

The manuscript deals with the development of electromobility in Norway and its impact on tax revenues. The detailed focus of the paper is on registration and road taxes directly related to the acquisition and operation of a road motor vehicle. The paper aims to verify whether a growing share of electric cars in Norway's fleet impacts the decrease in tax collection, namely road and registration tax. Norway was chosen because it is the country with the highest share of electric cars in the vehicle fleet in the world. Impacts on road and registration tax are investigated, focusing on 1998–2021. Our results suggest that the introduction of electromobility has a negative effect on the collection of road and registration tax, with the addition that this impact is statistically significant only in the case of registration tax. In other words, our research assumption was only confirmed in the case of the registration tax.

As a result of the new political stability achieved among Eritrea and Ethiopia, even though not completely consolidated after one year from the peace signed on 8 July 2018, the role of Asmara, the Eritrean capital, is under investigation to understand its potential impact on the economic and technological development of the Horn of Africa. In a region such as the Sub-Saharan one, the main challenge in energy is to guarantee a reliable electric grid based on Renewable Energy Sources (RESs). This paper proposes the development of an integrated urban mobility plan in Asmara, monitored by a performance analysis, and then it was simulated to power the service exclusively by a microgrid provided by photovoltaic panels using the software Homer pro, to sustain the demographic and economic growth of the city. From the analysis carried out, the implementation of the service required 52 e-buses, 2 e-minibuses, 7 e-taxis and 50 e-bikes. Furthermore, to economically and environmentally maintain the Project, a PV (Photovoltaic) plant with a surface area of 94,972 m2, equipped with a rated capacity of 4,966 kW. Furthermore, energy will be available at 0.1547 $/kWh. The aim of this work is to propose a future scenario of electric mobility enhancement for developing countries, evaluating their evolution over time to offer an efficient and suitable service throughout the city of Asmara.

An air traffic controller should manage aircraft movements per hour to ensure the safety and efficiency of the traffic system. This study proposed an innovative methodology to estimate the air traffic controllers’ workload through sector occupancy. Starting with a model for the workload of sector controllers designed by Eurocontrol for tower controllers, the authors defined a taskload model from real audio that occurred in an examined Terminal Control Area (TMA). Moreover, trombones have been implemented to sequence arrival flows in the simulated TMA. Therefore, an airside model has been reproduced using Fast Time Simulation software, and its capacity has been calculated in terms of occupancy due to approaching movements. The results permit to evaluate the impact of infrastructural and operative modifications on the sector capacity in terms of hourly entry count and occupancy. Total and maximum occupancy values have been deepened to identify the best predictive factor of controllers’ workload and to manage the airspace configuration.
