Table 1 A real-life setting of model parameters

From: A stochastic modeling approach for traffic analysis of a tramway system with virtual tags and local positioning

Parameter Description Value
Bound The percentage of upper and lower bounds of the uniform distribution variable: 1%, 3%,
  representing the time taken by the tram to travel an ordinary segment of the line: 5%, 7%, 10%,
  LowerBound=(ol/AverageVelocity)(1−Bound), and and 15%.
  UpperBound=(ol/AverageVelocity)(1+Bound).  
Epsilon The maximum error on the tram position calculated by the LDS system (Accuracy) variable: 1, 3, 5, and 10.
TMax The maximum time that a tram can wait in front of a tram signal variable: 4, 8, 12, 16,
  before contacting the OCC and 20.
p Probability that a message does not arrive at its destination variable: 0, 0.001, 0.003,
   0.005, and 0.01.
av The starting time interval between the trams variable: 20 and 30 s.
AverageVelocity Average tram speed 14.0 m/s
RateIXL IXL processing time in response to connection request and route request messages 0.1 s
RateNetwork Time of transmission of a message from OBCU to IXL or from IXL to OBCU 0.08 s
Delay The additional delay accumulated by a tram following the activation of the manual procedure 120 s
lentc The length of Track Circuit 45 m
nl The total number of segments 569
nt The total number of trams 36
ol The length of the ordinary segment 50 m
rrtotl The distance between the Route Request Tag and the tram signal 85 m
pt The time at the tram platform 20 s
