NETGRAF: A COMPUTER GRAPHICS AID TO THE OPERATION AND INTERPRETATION OF NETSIM (NETWORK SIMULATION MODEL), A TRAFFIC SIMULATION MODEL. PART I: OVERVIEW AND EXPERIMENTAL RESULTS

A computer system called NETGRAF is designed and used to aid the development of superior traffic control strategies. It is a supplement to a microscopic simulation model called NETSIM and allows the traffic planner to produce graphic displays of the simulation results obtained from running NETSIM. Displays of both network-wide and link-specific measures of effectiveness (MOE's) are posible as are comparison displays of MOE's from simulations of two alternative traffic control strategies. NETGRAF is interactive and operates with data stored on a tape that may contain a large number of NETSIM runs. It is written in FORTRAN IV, and uses standard graphics software. Limited tests have shown that novice users can find high performance solutions to small traffic control problems quickly and inexpensively, using NETGRAF as an aid to the problem-solving process. A NETGRAF User's Guide and a Programmer's Guide are also available as Parts 2 and 3 of this report.
