WISE Software Users Guide (2013)

Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

73 TABLE 8.1. “PROJECT INFORMATION” CONSTRAINTS Field GUI Value Comment Work zone speed 5 ≤ x ≤ the original speed limit; integer The work zone speed limit cannot be zero or cannot be faster than original speed limit. User-supplied diversion rate If user-defi ned diverge is TRUE, then 1 ≤ x ≤ 100; integer. If user-defi ned diverge is FALSE, then x = 0 If the route divergence uses user-defi ned rate, then 1 ≤ x ≤ 100; integer. If the route divergence computes diverge rate internally, then x = 0. Day cost Integer and nonnegative Night cost Integer and nonnegative Agency cost should be realistic. Capacity/lane reduction x ≥ 0.01; fl oat Percentage of capacity reduction due to work zone construction. Should be greater or equal to 0.01. Duration Integer; 1 ≤ x ≤ (latest end time – earliest start time); Note the caution below about duration-based strategies. Such strategies must not result in zero or negative duration. Duration-based strategy* If one project i was applied by a duration-based strategy k, then the duration of project i ≥ duration-based strategy + 1 Duration-based strategy cannot reduce the project duration to zero or negative. Link Single use Each project is unique link. *The reduction amount of the duration strategy specifi ed in “Project Information” must be less than the project duration. Each strategy and duration reduction is applied on a project-by-project basis. 8 DATA LIMITS

74 WISE SOFTWARE USERS GUIDE TABLE 8.2. “STRATEGY INFORMATION” CONSTRAINTS Field GUI Value Comment Demand-reduction rate 1 ≤ x ≤ 5; integer Demand-based strategy cannot reduce demand more than 5%. Demand-based radius 1 ≤ x ≤ 5; integer Demand-based strategy is only effective to reduce demand within a radius of 1 and 5 miles around the construction link. Demand-based cost Integer, nonnegative Agency cost. Duration reduction* Integer x ≥ 1 Duration-based cost Integer, nonnegative Agency cost. *Reduction means a reduction in construction duration time when the strategy is applied to a project. Each duration strategy is applied to a project on a case-by-case basis. TABLE 8.3. “PLANNING CHARACTERISTICS” CONSTRAINTS Field GUI Value Comment Value of time $5 < x < $300; float Between $5 and $300. Start time year 2010; integer Cannot be less than the year 2010. End time year 2030; integer Cannot exceed the year 2030. Day number of hours 1 ≤ x ≤ 12; float Between 1 and 12 hours of day. Night number of hours 1 ≤ x ≤ 12; float Between 1 and 12 hours of night. Seasonal factors 0.5 ≤ x ≤ 1.5; float Stay within reasonable range. Number of projects 1 ≤ x ≤ 20; integer The engine cannot exceed more than 20 projects. If any errors related to these data limitation fields are made, the user will be prompted by the engine, which will indicate that an error has been made and that an error file called “error_log.txt” was produced.
