Transportation Research Board Special Report
The results are briefly outlined of a complete traffic engineering study and recommendations are made for improving the traffic flow and reducing accidents. The network studied was a 30-block area with the major portion of the traffic in the 7-block central business district. The network simulation model was used to provide measures of effectiveness for existing traffic flow statistics. Cost/benefit analyses were computed by using projected accident reductions. Project costs were estimated at $120000 with a 0.66 year time-of-return based on accident reduction. Benefits were estimated by using a cost of $1.25/gal and $3 per person/h of delay. A factor of 3000 (a factor of 10 for daily x a factor of 300 for yearly) was multiplied by the hourly fuel and delay consumption to estimate a yearly value. NETSIM provides a more real-world view of existing and proposed traffic characteristics than other methods available.
