3. Input Requirements This section discusses the basic input requirements for PRETRANSYT It begins with a discussion of the minimum input requirements to produce various reports and then discusses the limitations to data input which exist This section is quite important in that it sets the minimum information for valid results as well as the limitations of the program Minimum Input Requirements Input Limitations Minimum Input Requirements Many of the input parameter values have defaults which eliminate the need to enter data for every parameter After the program is started or the File New menu or RESET PARAMETERS command is issued these default values can be viewed in any of the input dialogs of the Visual Mode or with the DATA or ASK commands in the Manual Mode The PRETRANSYT 27 Tutorial Chapter 3 ANALYSIS PROCEDURES default values of each command are also listed in the right hand section of the HELP displays which are generated by the Help Commands menu or the HELP command in the Manual Mode On the other hand there are a number of commands for which it is necessary to input data in order to produce legitimate results The most obvious of these are the NODELIST and SEQUENCE commands to describe the intersections under study and their phasings Values for these commands are needed to do most any function of the PRETRANSYT program As such examples of these inputs were illustrated in the initial exam

5. All counted trucks entered by this command may either be included or not included in the counts on the VEHICLECOUNTS command This is determined by the second parameter of the COUNTTYPE command Truck counts may not exceed 9999 Input should always be no more than four digits If cumulative counts are made with five digit counters only enter the last four digits When cumulative counts are being reduced if the difference is negative the counter turned over the 9999 mark to 0000 TURNS automatically adds 10 000 to the negative result PRETRANSYT B 172 Reference TRUCKPERCENTS TRUCKPERCENTS TRUCKPERCENTS 12 lt Truck Through Bus Percentage gt Defaults 12 2 Menus Groups PARAMETERS BASIC MOVEMENT The purpose of this command is to enter the truck and through bus heavy vehicle traffic percentage for each movement of the current intersection lt Truck Through Bus Percentage gt is the percentage of trucks and through buses in each movement volume and can be any number from 0 to 99 9 Its default value is 2 0 Notes TRUCKPERCENTS includes any designated heavy vehicles as defined by the 2000 Highway Capacity Manual PRETRANSYT B 173 Reference UPSTREAMVC UPSTREAMVC UPSTREAMVC 4 lt Upstream v c Ratio gt Defaults 4 0 0 Menus Groups PARAMETERS SIGNAL2000 The purpose of this command is to enter the v c ratio of the upstream intersection for each approach of the current intersection for SIGNAL2000
6. For DESIGN the lt Target Delay LOS gt entry of the LEVELOFSERVICE command sets the target delay or level of service which is to be achieved for all critical movements of the intersection If this target level is achieved with excess time still available at the intersection then the excess time is assigned to the phases according to the entries on the EXCESS command If no EXCESS entries have been made time is allocated proportionally to all phases However if EXCESS is used this provides a means to designate a worst case delay LOS performance level for all critical movements and to assign all additional time to the priority movements of the EXCESS command This is the preferred optimization scheme for the DESIGN function of SIGNAL2000 see Appendix C for more details The excess time will be allocated to the phases in which the specified movements occur If the movements specified occur in more than one phase the excess time will be allocated to each in proportion to the g C required by each If a specified movement occurs in more than one phase its excess time phase will be designated as the single phase serving the movement i e if movement 2 is specified with sequence 21 the excess will go to the north south through phase PRETRANSYT B 88 Reference EXPORT EXPORT EXPORT lt File AUTO STACK gt lt Display Output gt lt Auto Option gt Defaults AUTO NO VIEW Menus Groups RESULTS EXPORT The purpose of this
7. gt Better Default System Cycle Length Used The system cycle length or cycle optimization range fora TRANSYT analysis is determined by the cycle information provided for the intersection which is designated as the MASTERNODE intersection In the event that the MASTERNODE is not defined or if it points to an intersection not in the current SUBSYSTEM the program now uses the first intersection of the SUBSYSTEM rather than the first intersection of the NODELIST to define the default system cycle length or cycle optimization range gt Better Scale Factor Determined Between User Coordinates and Ground Coordinates TEAPAC programs allow the use of an arbitrary scaled coordinate system to be used when entering NODELOCATION values When this is the case and ground coordinates are needed the program deduces an appropriate scale factor between the user coordinates and ground coordinates based on link lengths provided while recognizing the possibility of certain tolerable errors in locating each node and the impact of curved links on this process An improved method to eliminate outliers from this scale determination has been implemented for higher probability of a better result in cases which include NODELOCATION input errors gt Further Enhancements to Ver 5 12 Interface The Ver 5 12 TEAPAC interface found in most TEAPAC programs has been further refined with additional features to aid in the analysis process These include 1 sa

17. Release 7 of TRANSYT 7F corrected a problem associated with using the card type 54 for a cycle optimization run Until this release problems with the cycle optimization precluded its use and the cycle optimization was performed from PRETRANSYT using a combination of a card type 50 and the card types 4 and 6 Now when the target program is Release 7 or higher the card type 54 is used A final optimization for the best cycle is no longer performed as the user should select the best cycle before a final optimization is done gt New IMPORT Error Messages Help Understand Import Problems Several possible and typical errors which may be encountered when importing data from TRANSYT output files are now identified with a new PRETRANSYT error message to identify these conditions These are listed below The most common will be that PRETRANSYT detects a different version of TRANSYT in the output file than that indicated by the OUTPUT command This will occur if the OUTPUT option in PRETRANSYT is not consistent with the version of TRANSYT which created the output file Be especially careful of this problem if PRETRANSYT H 293 Reference Release 7 of TRANSYT is being run with an old data set which had an earlier release of TRANSYT saved with the OUTPUT command file read error usually due to a bad diskette no import TRANSYT 7F Release 6 or higher not found no import controller settings not found in TRANSYT output file no import node num

19. TEAPAC System Error Messages Appendix F Topics TEAPAC system messages are displayed by all TEAPAC programs whenever an identifiable fault condition is detected The message may be due to the command itself to one of its parameters or as a result of the action taken by the command When a condition is detected an error number and message is displayed identifying the type of condition encountered This appendix discusses the TEAPAC messages and their meanings followed by a discussion of potential causes and actions which may correct the conditions Table F 1 summarizes the error numbers which are discussed in this appendix The remainder of the appendix lists and discusses each of these messages in numerical order The messages in this appendix are specifically TEAPAC system messages which can be detected by any TEAPAC program These are identified by a prefix of TPC in the error code Appendix E lists those errors which are unique to a specific TEAPAC program These are identified by a different prefix XXX related to the program being run Appendix G lists those errors which are generated by the operating environment being used and as such are unique to that operating environment The form of these error messages is dependent upon the operating environment being used Messages are either WARNINGS or ERRORS A WARNING might be advisory only while ERRORS are usually fatal and terminate the current action Once an error message has been d

SAVE command SAVE PARAMETERS will now save all information for every intersection in the NODELIST as well as system information rather than only the current intersection This provides an effective way of saving all information entered though not particularly efficient means of retaining information which might be used by other TEAPAC programs Of particular note is that the SAVEd format is not the same as SIGNAL97 and thus should not be used if the data was created by or will be used by SIGNAL97 In this event SIGNAL97 should be used to create and maintain the data base of information and PRETRANSYT should only be used to read this information It is also important to note that the number of lines SAVEd by PRETRANSYT may vary depending on what information has been entered or changed so stacking of PRETRANSYT scenarios in a single file should be done with great care if at all gt New MINIMUMS Command Implemented The preliminary testing of green phase minimums has been consummated in a new command MINIMUMS using the same format as SIGNAL97 with 12 minimum green times one for each movement The default values are 5 seconds for each movement The USERMODEL command has been returned to its normal inactive state following this implementation Since TRANSYT uses a limited facility for controlling phase minimums in its optimization this implementation is necessarily limited in the same fashion The difficulty is that TRANSYT applies minimu
