Exclusive bus lane (EBL) is one of the most common transit prioritization strategies implemented to improve transit speed. However, one major drawback of implementing EBLs is the associated reduction ...in road capacity left for other road users. In corridors with EBLs and infrequent bus service, the lanes are underutilized for extended periods of time. Dynamic bus lane (DBL), a new priority strategy enabled by vehicle connectivity, can provide buses with priority while allowing the general traffic to access the bus lane when buses are not present. Although the DBL concept is promising, a limited number of studies have explored its effectiveness under various conditions. Thus, this paper investigates the impacts of DBLs through a comparison with EBLs and mixed traffic operation under different levels of traffic demand and transit frequency. As a case study, the Eglinton East corridor in Toronto, Canada, was simulated using Aimsun Next, and different scenarios of behavioral impacts were considered in the analysis. The results reveal that DBL is a promising strategy with potential to improve the overall corridor performance over a wide range of traffic and transit service conditions, especially under intermediate traffic demand levels. On the other hand, EBL can be an efficient prioritization strategy that improves the overall corridor performance under high traffic demand and high transit frequency levels, but only if accompanied by a major mode shift from auto to transit.
Background:
Although many studies have identified the key factors influencing travel mode, they have typically centred around survey data, which has several limitations. In this research, actual ...transport data (GPS) has been provided by Google Environment Insights Explorer (EIE) for 169 municipalities in Australia across 2018 and 2019.
Objective:
A key outcome of this paper is to project the independent impact of new public transport networks (rail, bus and tram) on mode shift away from vehicles for each municipality and estimate the total distance travelled.
Methods:
This study uses a combination of linear regression and logit transformations to predict the proportion of automobile transport relative to all other transport modes.
Results:
The results suggest that South Australia would benefit from a metropolitan northeast rail line, New South Wales would benefit from a metropolitan southwest tram line, and Victoria would benefit from a metropolitan southeast bus service.
Conclusion:
Although the analysis is somewhat crude, it utilises open-access data and thus could be easily replicated for any country globally, which could be greatly beneficial, especially for countries with low socio-demographic backgrounds.
A városi közlekedés napjainkban jelentős kihívás elé állítja az ott lakókat. Az elmúlt években jelentős mértékben megnövekedett, a vírushelyzet miatt tovább erősödő személygépjármű forgalom is azt ...mutatja, hogy a lakosság a közösségi közlekedési eszközök használatáról az egyéni közlekedés irányába köteleződött el. Az élhető városi lét megteremtése érdekében sürgős lépéseket kell megtenni, amellyel a városi mobilitás a lakosság által elvárt módon fenntartható marad. Ehhez többféle eszköz áll a városok vezetőinek rendelkezésre. Ilyenek lehetnek a mikromobilitási eszközök használatának, a megosztáson alapuló rendszerek bevezetése, valamint a személygépjármű forgalom korlátozó intézkedések bevezetése. Ezek mellett kézenfekvő a közösségi közlekedés fejlesztése, a lakosság ezen irányba történő terelése. A legtöbb nagyváros napjainkban ebbe az irányba törekszik, azzal, hogy ezen hálózatait és szolgáltatásait fejleszti, annak érdekében, hogy ezen közlekedési rendszerek elérhetőségét és vonzerejét javítsa. Több európai nagyváros annak érdekében, hogy a lakosság minél nagyobb arányban használja a közösségi közlekedést, azt részlegesen vagy teljes mértékben ingyenessé tette. Ez a törekvés hazánkban sem ismeretlen, hiszen a lakosság jelentős része több évtizede ingyenesen veheti igénybe ezen közlekedési formát. Ugyanakkor a teljes ingyenesség bevezetése esetén szükséges megvizsgálni annak hatásait gazdasági és társadalmi oldalról.
Public transportation is important for older adults to meet their mobility needs and obtain external support. However, little is known about the elderly population with disabilities using public ...transportation. Using a nationally representative sample from the China Family Panel Studies (CFPS) for 2016, 2018, and 2020, we examined the elderly and public transportation disability (E&PTD) rate and its determinants in Chinese adults aged 45 years and above; the E&PTD rate in this population was 9.65%. The results showed that factors such as being female, age, and family size increased the likelihood of E&PTD in older adults. Married older adults with more education, better intelligence, higher incomes, receiving a pension, and living in urban areas and pilot provinces of healthcare reform were less likely to have E&PTD. This study provides an important policy reference for providing better public transportation services for E&PTDs.

This article represents the analysis results of normative legal regulation in the transport services field for people with limited mobility (LMP) and assessment methods of transport services quality ...provided by public transport for the same social group. The main conclusions of the significance examination of quality parameters are given below. The essential problems of transport accessibility provision were defined by materials of sociological polls.
Drones have been regarded as a promising means for future delivery industry by many logistics companies. Several drone-based delivery systems have been proposed but they generally have a drawback in ...delivering customers locating far from warehouses. This paper proposes an alternative system based on a public transportation network. This system has the merit of enlarging the delivery range. As the public transportation network is actually a stochastic time-dependent network, we focus on the reliable drone path planning problem (RDPP). We present a stochastic model to characterize the path traversal time and develop a label setting algorithm to construct the reliable drone path. Furthermore, we consider the limited battery lifetime of the drone to determine whether a path is feasible, and we account this as a constraint in the optimization model. To accommodate the feasibility, the developed label setting algorithm is extended by adding a simple operation. The complexity of the developed algorithm is analyzed and how it works is demonstrated via a case study.
Developing public transportation is an effective way to alleviate traffic congestion and reduce fossil fuel consumption. However, the result of ineffective public transport planning can be that some ...bus lines have long overlapping intervals, and share many common stops between them, which causes a significant waste of resources. The current bus scheduling method does not consider the imbalance of passenger flow between different stops or combine the overlapping interval with transit mixed scheduling, including all-stop and stop-skipping services. Therefore, based on the analysis of the characteristics of overlapping interval, this paper proposes a combined bus scheduling method, which includes both all-stop and stop-skipping bus services. The method is a deterministic method applied in the scheduling stage of transit planning. The method optimizes scheduling strategies by minimizing total passenger travel time, including the waiting time and the in-vehicle travel time, and the line frequency of each bus service is taken as the decision variable. Then a genetic algorithm is designed to find the optimal solution. The model is verified by two bus lines in Changchun city. The experimental results showed that the proposed model could reduce total passenger travel time by 7.71% compared with the existing scheduling method. The combined bus scheduling method can supplement the research on bus scheduling of overlapping routes and provide suggestions for operators.
