ExportLocationData exorts the location data from the mbta API

func ExportSpecialEdgesLocationData ¶

func ExportSpecialEdgesLocationData(specialEdges SpecialEdges) error

ExportSpecialEdgesLocationData exorts the location data from the mbta API for the middle stops of special edges

func GetDateFromEdgeDataFilename ¶

func GetDateFromEdgeDataFilename(filename string) (time.Time, error)

GetDateFromEdgeDataFilename return the date from the filename of a EdgeData file

func GetEdgeKey ¶

func GetEdgeKey(stopAName, stopBName string) string

GetEdgeKey returns the map key for an edge between two stops

func GetEdgeKeyWalking ¶

func GetEdgeKeyWalking(stopAName, stopBName string) string

GetEdgeKeyWalking returns the map key for an edge between two stops with walking

func GetStopCoordinatesForGoogleAPI ¶

func GetStopCoordinatesForGoogleAPI()

GetStopCoordinatesForGoogleAPI calculates and saves mbta api location data

func GetTransitDataFilename ¶

func GetTransitDataFilename(startTime time.Time, interval time.Duration) string

GetTransitDataFilename returns the filename that represents this data

func GetTransitDataWithGoogleAPI ¶

func GetTransitDataWithGoogleAPI(startTime, endTime time.Time, interval time.Duration, apiKeyFile string)

GetTransitDataWithGoogleAPI generates a json file of distance data of edges

func ParseDateToEST ¶

func ParseDateToEST(date string) (time.Time, error)

ParseDateToEST takes in a string of format EdgeDataTimeLocation and returns a time.Time variable in EST

func ReconstructRoute ¶

func ReconstructRoute(route []Stop, startTime time.Time, apiKeyFile string)

ReconstructRoute will print out all of the directions and times of each step of the route

func WriteEdgeDataToFile ¶

func WriteEdgeDataToFile(edges Edges, startTime time.Time, interval time.Duration) error

WriteEdgeDataToFile writes the edge data to a file

Types ¶

type EdgeTimes ¶

type EdgeTimes map[int64]time.Duration

EdgeTimes stores the time each edge took to traverse (unix time -> duration for that time)

type Edges ¶

type Edges map[string]EdgeTimes

Edges a map of all edges by edge key

func GetTransitDataForAnEdgeWithGoogleAPI ¶

func GetTransitDataForAnEdgeWithGoogleAPI(stopA, stopB *Stop, startTime, endTime time.Time, interval time.Duration, apiKeyFile string) Edges

GetTransitDataForAnEdgeWithGoogleAPI returns edge data for a particular edge stopA->stopB

func ImportEdgeData ¶

func ImportEdgeData(filename string) (Edges, error)

ImportEdgeData gets the edge data from a file

type SpecialEdge ¶

type SpecialEdge struct {
	Stop      *Stop `json:"Stop"`
	NoWalking bool  `json:"no_walking,omitempty"`
}

SpecialEdge holds data about a special edge, including its midstop and if a walking edge is allowed

type SpecialEdgeFiles ¶

type SpecialEdgeFiles string

SpecialEdgeFiles enum for files containing special edges

const (
	// SpecialEdgesFile the file that stores the edges with multiple ways to go
	SpecialEdgesFile SpecialEdgeFiles = "datacollection/special_edges.json"
	// SpecialEdgesFileWithLocationData the file that stores the edges with multiple ways to go and the middle stop locations
	SpecialEdgesFileWithLocationData SpecialEdgeFiles = "datacollection/special_edges_with_location_data.json"
)

type SpecialEdges ¶

type SpecialEdges map[string]SpecialEdge

SpecialEdges holds which edges need a stop in between them (and can also possibly walk between them)

func ReadSpecialEdgesFromFile ¶

func ReadSpecialEdgesFromFile(filename SpecialEdgeFiles) (SpecialEdges, error)

ReadSpecialEdgesFromFile reads in the special edges from a file (probably special_edges.json)

type Stop ¶
