Solving the School Bus Routing Problem by Maximizing Trip Compatibility

Ali Shafahi, Zhongxiang Wang, Ali Haghani
2017 Transportation Research Record  
This paper proposes a new formulation for the multi-school homogeneous fleet routing problem that maximizes trip compatibility while minimizing total travel time.  ...  School bus planning is usually divided into routing and scheduling due to the complexity of solving them concurrently.  ...  Another one is the double counting of compatibility problem that was mentioned at the end of the methodology section.  ...

We show that an integrated multi-school bus routing and scheduling can be formulated with the help of trip compatibility. A novel decomposition algorithm is proposed to solve the integrated model.  ...  Due to the growth of the computing power, the spotlight has been shed on solving the combined problem of the school bus routing and scheduling problem.  ...  Shafahi et al. (2017) provided a new alternative to solve school bus routing problem by minimizing the number of trips and the total travel time while maximizing the trip compatibility.  ...

Optimizing schools' start time and bus routes

Dimitris Bertsimas, Arthur Delarue, Sebastien Martin
2019 Proceedings of the National Academy of Sciences of the United States of America  
We present an optimization model for the school time selection problem (STSP), which relies on a school bus routing algorithm that we call biobjective routing decomposition (BiRD).  ...  To reduce costs by reusing buses between schools, many districts spread start times across the morning.  ...  Google Maps helped make this work possible by providing point-to-point travel time estimates for all locations in Boston.  ...

Balanced scheduling of school bus trips using a perfect matching heuristic [article]

Ali Shafahi, Sanaz Aliari, Ali Haghani
2018 arXiv   pre-print
A California case study with 54 trips and the Howard County Public School System (HCPSS) with 994 trips.  ...  In the school bus scheduling problem, the main contributing factor to the cost is the number of buses needed for the operations.  ...  The problem of chaining trips, each being served by a single bus is called school bus blocking/scheduling problem.  ...

Shareability Network Based Decomposition Approach for Solving Large-scale Single School Routing Problems [article]

Xiaotong Guo, Samitha Samaranayake
2022 arXiv   pre-print
We consider the Single School Routing Problem (SSRP) where students from a single school are picked up by a fleet of school buses, subject to a set of constraints.  ...  The constraints that are typically imposed for school buses are bus capacity, a maximum student walking distance to a pickup point, and a maximum commute time for each student.  ...  The report is funded, partially or entirely, by a grant from the U.S. Department of Transportations University Transportation Centers Program. However, the U.S.  ...

Visualization of Transit Mobility and Performance

Anibal Galindez, Ricardo Mireles-Cordova
2001 Journal of Public Transportation  
It serves as a powerful tool to evaluate bus route pe,formance.  ...  Different demand markets for transit (rail, bus fixed-route, shuttles, community circulators, vanpools, etc.) can be appraised and the effectiveness of current transit in serving these markets can be visualized  ...  Trip lengths vary by line and type of service, but the system wide average trip length is 3. 7 miles ( 6 kilometers). A high transfer rate is a by-product of the system's grid design.  ...

An overview on vehicle scheduling models

Stefan Bunte, Natalia Kliewer
2009 Public Transport  
The vehicle scheduling problem, arising in public transport bus companies, addresses the task of assigning buses to cover a given set of timetabled trips with consideration of practical requirements, such  ...  An optimal schedule is characterized by minimal fleet size and minimal operational costs. Various publications were released as a result of extensively research in the last decades on this topic.  ...  [29] reports a further route constraint with practical relevance: some bus companies prefer to pose a restriction for bus line changes in vehicle routes.  ...

Hurricane evacuation planning using public transportation

Rahul Swamy, Jee Eun Kang, Rajan Batta, Younshik Chung
2017 Socio-Economic Planning Sciences  
In the next stage, each route is assigned a trip number such that 1) routes with higher demand require more trips, and 2) two successive trips to a route are spaced evenly.  ...  This is done by weighing each location based on the accumulated demand, and favoring multiple routes to pass through a location with higher demand.  ...  For each route r, a relative trip number is calculated such that the first trip on a route has a relative trip number of 1. Let n r (k) be the relative trip number of trip k on route r.  ...
