run {cartools}R Documentation

The run function is a wrapper for the trial and plotfollow3 functions.

Description

The run function is a wrapper for the trial and plotfollow3 functions.

Usage

run(nveh, ulead, ulead.sd, ubrkdown, ubrkdown.sd, k, k.sd, d, leff, xlim,
  ylim)

Arguments

nveh

number of vehicles in the investigation or vehicle = 1, 2, ..., nveh, a number

ulead

lead vehicle speed (mph) at time t0, i.e., before breakdown, a number

ulead.sd

standard deviation of ulead, a number

ubrkdown

breakdown speed (mph) of lead vehicle, a number

ubrkdown.sd

standard deviation of ubrkdown, a number

k

traffic density (vehicles per mile, vpm) of the pre-breakdown state, a number

k.sd

standard deviation of following vehicle breakdown speed, a number

d

deceleration rate of the lead l vehicle, a number

leff

effective vehicle length (feet), a number

xlim

plot range along the t axis, a vector

ylim

plot range along the x axis, a vector

Value

The function returns an t-x image and eight lists: output[[1]] returns a vector of run input values; output[[2]] returns a matrix of pre-breakdown ulead speed, breakdown ubrkdown speed, pre-breakdown k density values for each vehicle; output[[3]] returns a time matrix consisting of t0,t1,t2,t3,t4,t5; output[[4]], output[[5]], output[[6]] and output[[7]] returns matrices of speed u, location x and safe headway h values for each vehicle at times t0,t1,t2,t3, respectively. Finally, output[[8]] returns a list the cflist list consisting of information stored as L and Fw matrices.

Examples

run(10, 63, 10, 0,  0,  55, 5, 15, 14, c(0, 20),c(-1000, 200))
run(10, 63, 10, 34, 0.1,  55, 5, 15, 14, c(0, 60),c(-2000, 4000))
run(10, 63, 10, 10,  1,  55, 5, 15, 14, c(0, 40),c(-2000, 2500))
