Instructions for Traffic Monitoring System

___________________________________________________________________

Background Federal transportation legislation, TEA-21, requires development and implementation of a Traffic Monitoring System (TMS). The system is to:

• Collect and process highway and vehicle traffic data sufficient to meet management information needs of decision-makers and modeling needs of technical support staff; and

• Support the six highway management systems that were at one time mandated by previous federal transportation legislation, ISTEA, and continue in use at most state and Metropolitan Planning Organizations.

Part of TMS requires information on used and available transit system capacity, and the location of this capacity for use in modeling. The Ohio Department of Transportation (ODOT) is responsible for collecting this data from Ohio urban transit systems and distributing the data to the appropriate MPO staff.

___________________________________________________________________

Purpose This document provides instructions to transit systems on using an Excel workbook template for reporting TMS data to the Ohio DOT.

___________________________________________________________________

Workbook A diskette accompanies these instructions that contains an Excel workbook named

"Ohio DOT TMS 2001.xls" -- a workbook is a file that contains multiple individual spreadsheets. The spreadsheet names and contents in the "Ohio DOT TMS 2001.xls" workbook are:

System -- Transit system name and contact information.

Bus Service A, Bus Service B, etc. -- Bus route capacity data. Use one table for each route. In order to accommodate both medium and large transit systems, there are four spreadsheets with thirty tables each, thus accommodating up to 120 routes. Tables in Bus Service A are identified as A-1, A-2, etc.

Rail Service -- Rail/fixed guideway line capacity data. Use one table per rail line. There are eight tables in this spreadsheet.

Bus Summary -- Summary of route and system data from the route tables.

Rail Summary -- Summary of rail line and system data from the rail line tables.

Glossary -- Description of various data fields. Each column in a table is a data field.

Example -- An example of a completed table.

___________________________________________________________________

Using the Complete a table for each route in your system in order to provide the required TMS

Workbook data. Before you begin completing the tables, review and understand the following general instruction points.

❑ Use a normal service day to provide the requested service data. Do not provide data from low service days, such as rainy or cold winter days, nor from busy special events.

❑ Provide the route identification information in the first row of the table.

❑ There are six rows of requested service data. These rows represent three service periods, i.e., AM Peak, PM Peak and Off Peak, by the two vehicle directions, usually Inbound and Outbound.

❑ Make sure that all the service hours for the particular route are included in the reporting for these three service periods.

❑ The Glossary defines each of the data fields (columns). Both the workbook and this instruction document contain a copy of the Glossary.

❑ The table will automatically compute the Load Factor data fields (columns) and Daily Totals row based on the data you enter. Review these computed and total figures to determine if the data appears correct.

❑ The Bus Summary and Rail Summary spreadsheets display route, line and system service totals. After completing the route and rail line tables, use these summaries to help determine whether you have included all the system's bus and rail service.

❑ To print a copy of any spreadsheet, highlight the desired cells and click the print icon.

Glossary The Glossary in the following table defines the data field columns that you will need to understand in order to complete the table.

|Term |Definition |

|Table |There is one table for each bus route or rail line. For easier organization, the bus route tables are divided|

| |among four spreadsheets (Bus Service -A, Bus Service -B, etc.), and each spreadsheet contains 30 tables (A-1, |

| |A-2, etc.). |

|Route Name |Name of route for bus or van service. Each route should have six entries -- an inbound and outbound entry for|

| |each of the three service periods. |

|Line Name |Name of line for rail or other fixed-guideway service. Each route should have six entries -- an inbound and |

| |outbound entry for each of the three service periods. |

|Direction |Indicates direction. Use (I) Inbound and (O) Outbound for radial routes/lines. Use cardinal direction for |

| |non-radial routes/lines, ex., (E) Eastbound. |

|Period |Period for which count is made, ex., 7:00am to 9:00am. The six entries for each route/line should cover all |

| |the daily service hours for that route/line. |

|Number of Vehicles |Number of vehicles used to provide bus or van service on that route direction during that period. Example: 1 |

| |bus providing off-peak service in both directions = 1 vehicle. |

|Number of Cars |Number of cars used to provide rail or other fixed-guideway service on that line direction during that period.|

| |Example: 3 car train providing off-peak service in both directions = 3 cars. |

|Seated Capacity |Number of seated passenger trips that vehicle(s) can carry in route direction for indicated period. Example: |

| |3 runs/hour (20 min. headway) by 30-passenger capacity vehicle by 2 hours = 180. |

|Full Capacity |Number of seated and standing passenger trips that car(s) can carry in route direction for indicated period. |

| |Example: 3 trains/hour (20 min. headway) by three 40-passenger capacity cars/train by 2 hours = 720. |

|Load Factor |# of Passengers/seated capacity for bus and vans, or # of Passengers/full capacity for rail and other fixed |

| |guideway, for that route/line direction at any designated point in time. For this report, the load factor is |

| |measured at the maximum load point (i.e. the point at which the largest number of passengers are aboard the |

| |vehicle). |

|Estimated Average |This is the average of several of the highest load factors on the vehicles or trains for that route direction |

|Highest Load Factor |during the indicated period. This will most likely have to be estimated. Example: 2 vehicles/hour (30 min. |

| |headway), over a 2-hour peak period, with the highest estimated load factor between any stop on each run being|

| |0.6, 1.0, 1.0 and 0.6, yields an average of 0.8. |

|Highest Load Factor |Address, street intersection or landmark that clearly distinguishes the stop where the highest load factor |

|Stop Location |occurs. |
