Autonomous Bus Scheduling System Design Report
== Autonomous Bus Scheduling System Design Report ==
== Introduction ==


=== Background ===
The final report can be found [[Media:Report.pdf|here]].


Public transportation has been around for a couple of decades now. It started with the stagecoach in the nineteenth century. Later on came the steam trains which were capable of carry large capacity of people at the same time.  The trains were too big to travel in city themselfs, so the tram was invented. However not city are capable of creating a tramrail network. So with the increasing demands of mobility in the sixties, busses started to be used for public transportation in cities around the Netherlands and the rest of europe.
The survey results can be found [https://www.dropbox.com/s/19t3vq5oocd02qb/Survey.xlsx?dl=0 here].
Bus stops were created around cities and a static scheduling system was implemented. This static scheduling system uses a fixed time table around the city. The busses follow fixed routes each time and do not take into account if there are any people waiting at a bus stop or not. Meaning that the busses do not take a shorter route when nobody is willing to stop of is waiting a certain bus stop. This means it is time for a dynamic system, this will be the main focus in this report. The new scheduling system for busses aims to create a more efficient passenger flow. It will be able to send extra busses to bus stops that are or are getting too crowded and also the system will choose a shorter route to it’s destination when no passengers are waiting at the coming bus stops. Users can check in at the bus stop or with their mobile phone apps. The scheduling system will then optimize the routes by taking this information into account. A small part of the report will discusses the possibility of using autonomous busses in the new dynamic scheduling system, analyzing the impact of user, society and enterprise.
 
Different approaches can be used to optimize this schedule. Those will be analyzed and take feedback data from a survey. This data will be inputted in a simulation in order to analyze the consequence of the different needs of the users. Furthermore in this report the infrastructure will be redesigned. The most important infrastructure alteration will be the placement of the bus depot. The simulation will also be used to validate the new dynamic scheduling system. 
 
The validation will have with different requirement like waiting time and crowdiness but also with happiness. This is a design report for dynamic scheduling bus system, incorporating the needs of the User, Society and Enterprise.

| A potential maximum waiting time of 20% longer than it currently is.

'''1.2.1'''
 
When a bus skips a few bus stops, it will arrive sooner than expected at the next stops, which means that people might have to wait longer than usual for next bus if that one does not skip any. This will lead to potential longer waiting times. However, this also means that there are also potential shorter waiting times between busses, if the first bus does not skip any stops, but the second one does.
 
 
'''1.2.2'''
 
When there are stops that can be skipped, more efficient bus routes can be used to reduce the travel time. This will not be possible during rush hours, because the bus stops will be too crowded, which means that there will barely be any stops the bus can skip.
In the following picture shows a fragment of the bus route between Eindhoven and Veldhoven.

'''1.2.3'''
 
Happiness will be “quantified” in the simulation, and the decrease in travel time should be weighing more heavily than the potential increase in waiting time, and perhaps the troubles caused by the use of the app to sign up for bus rides.
 
=== Requirements ===
 
=== Proposed Plan of Action ===
 
As can be seen, we have already clarified the background, objectives, and the requirements regarding the autonomous bus scheduling system. Now, we will we explain how we are going to investigate whether such a system could replace the current scheduling system.
We have three main cases we should distinguish:
 
1. Will the ABSS decrease the average waiting and traveling time of the passengers?
 
2. Will the ABSS enhance the beneficial looking at the three USE-aspects?
 
3. Should autonomous busses replace the bus drivers?
 
In order to investigate whether or not the ABSS will decrease the average waiting and traveling time, we will create a simulation with as well as possible real life features. With real life features a Poisson Process for passenger arriving time for example is meant. We use <s>Unity3D (Frank should update it)</s>  to make this simulation.
 
For the second and last case we will conduct a [http://cstwiki.wtb.tue.nl/index.php?title=0LAUK0_2015_01_Survey link survey] and distribute them among at least 70 bus passengers, the passengers are not entirely randomly selected, but are selected so that in each age and gender category we have about the same amount of people.
 
Besides the survey we will study research that already has been done in scientific journals or informative magazines, analyze those findings and apply them in our own investigation.
