Bus bunching is an instability problem where buses operating on high-frequency public transport lines arrive at stops in bunches. This work unveils that bus-following models can be used to design bus-to-bus cooperative control strategies and mitigate bunching. The use of avoids the explicit modelling bus-stops, which would render resulting discrete, with events occurring arbitrary time interval...

Transit travelers expend a great deal of time and energy on out-of-vehicle walking and waiting, which significantly affects their perceived burdens of travel. Accordingly, this article is concerned with ways to reduce the perceived burdens of out-of-vehicle time spent walking, waiting, and transferring to improve users’ experience at transit stops and stations. We surveyed 749 transit users at ...

Due to continuous urban sprawl, large-scale bus network design has become a major challenge in transport planning. The increase population and scale makes the factors considered route increasingly complex. Contemporary public transportation problems are based more on efficiency goals such as accessibility comfort of network, which increases difficulty analyzing problem. Bus is not only an NP-ha...

in this paper, a new approach was presented for bus network design which took the effects of three out of four stages of the bus planning process into account. the presented model consisted of three majors steps 1- network design procedure (ndp), 2- frequency determination and assignment procedure (fdap), and 3- network evaluation procedure (nep). genetic algorithm (ga) was utilized to solve th...

This paper examines the characteristics of intercity bus riders within Tennessee and proposes methods to identify service gaps and prioritize network expansion, particularly focusing on rural-urban connections. Data were collected through an on-board survey and compared with intercity auto trips. Compared to personal auto users, intercity bus riders are more likely to be of minority races, unem...

Bus accident is a major health problem for bus drivers.  To identify the risk factors involved in bus accidents and to design a model showing the relation between the risk factors and bus driver’s health status, 219 bus drivers who worked for travel agencies in two areas of west and central Iran were enrolled into this study.  We used a questionnaire to gather information regarding both the bus...

this paper proposes a new method for transmission loss allocation. the share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. then, it is applied to the total network transmission lines. in the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introduced...

in this paper, a new method based on branch placement for the optimal positioning of phasor measurement units (pmus) in power systems is proposed. in this method, the pmus are in type of single-channel and are installed at the beginning of the branches. therefore, they are able to measure the bus voltages. also, the installation of the pmus on the branches increases the security of observabilit...
