Yakima Transit Statistics

• Population of 80,000• 9 fixed routes running

6am to 7pm (not Sunday)• 2005 Budget of $4.4M• Over 1 million

passengers in 2004• 309 Service Days• Expanding service to

other local cities


Why TransitAVL?

• Dispatching Tool

• Show current bus positions on route

• Calculate estimated arrival times

• Share information with riders

• Measure Yakima Transit performance

• Leverage Yakima’s other AVL/GIS/Web knowledge


TransitAVL Hardware

• Sierra Wireless MP750 Modems

• Cost $950/unit $40/per month (AYCE-$80)

• Integrated Trimble GPS using TAIP

• Consistent position messaging

• Panic Switch

• No session stealing as with CDPD

• Some latency

GPS Characteristics

• Reporting Interval 10 seconds >12 meters

• Configurable from TransitAVL server

• Generally accurate to 20 feet

• Regionalized Selective Availability

• Good GPRS coverage


TransitAVL Rules• Simple, Easy to follow…

• Buses must be assigned to routes

• Any number of buses assigned to route

• Route lines must follow driven path

• GIS line direction must follow driven path

• Times used between stops are from bus book


Building Routes in GIS

• Leverage Existing GIS Data

• Use actual AVL data

• Generalize in GIS

• Add/Update attributes– Stop Names– Time to travel– Sequence each segment

Position Report Accuracy


Time, Speed & Delay


Bus Route 5 – Single Segment


Calculating Arrival Times

• Buses assigned to specific routes

• Recalculated with every new position report

• Times recalculated for major stop points

• Use position to select route segment

• Interpolation/percentage traveled segment

• Add interpolated time to other road segments by sequence number


Travel & Arrival Times


TransitAVL Server• Basic GIS Application• Receives all position reports• Calculates/estimates arrival times• Controls bus assignments• Relays position reports, bus assignments & alerts

to TransitClients and TransitWeb• Saves position data for later examination• Update/Add/Delete Buses, Routes, Users


TransitClient

• Gives supervisors and staff a real-time view

• Receives assignments, bus positions and alerts from TransitAVL server

• Calculates/estimates arrival times


General Features

• Toggle bus routes– Turns off route line– Only shows buses for displayed routes

• User defined zoom areas

• Bus speed and heading information


Overview Map


Single Route

TransitWeb - iBus• Many of the same features as TransitClient

• TransitWeb receives position reports

• Works on most browsers (PC, mac, Unix)

• Cookies save your settings– Map extent, map size, address, my stop, routes

• Automatic refresh is configurable

• Refreshes only times and positions

• Uses JPG and GIF images

AVL Data• Transit Analysis

– Rider Queries– Route Timing– Performance

• General Analysis– Travel Speed Study– GPRS Signal Quality

Solid Waste AVL

• ArcMap AVL Server Connection

• Mapping Delay

• Showing Excessive Speed

• Route Planning
