Geospatial Technology in Urban Transport Dr.R.S.Moorthy Head (Projects) UMTC, New Delhi Geospatial Forum February 9, 2012 India
Urban Areas ….. Dynamic Master Plan Economical, Political & Technological Changes in Urban Areas & Transportation System
Changes need to be incorporated in a continuous Planning Process with changed input – New Data
Developing countries Availability data - a major bottleneck in providing solution Short cut method, piece meal solutions & subjective decision making
Piece-meal solutions - Not desirable Qualitative statements - Not acceptable
Quantitative assessment - to justify the solutions Feasible, Viable, Suitable & Acceptable Besides, Time & Cost effective Otherwise ……. ……...
Professional approach & Quantitative solutions Solutions >> Scientific models Models >> Relevant data Data >> Reliable, Accurate, Retrievable Cost & Time effective
To achieve …. Information System User friendly tool
Spatial information Technologies • Remote Sensing (RS) • Global Positioning System (GPS) • Geographical Information System(GIS) Useful & Relevant in Transportation
Highway Information Pavement Management System Change detection ( enchroachment / surface condition) Vehicle Tracking Urban Transportation Planning Transit Route Planning On-line Transit Information System Road Alignment selection Intelligent Transportation System On-line Traffic Information System
Urban Land useTransportation Planning Travel Demand Assessment
To understand Usefulness & Relevance & To demonstrate Capabilities & Efficiency of GST Special Assignments Software :Trans CAD
Thane Transport System Rail System Road System BusTransport System ParaTransitSystem Re look at Intra city Transport System MRTS (proposed)
Sources of Data Secondary source: Satellite imageries - NRSA, IKONOS Maps-SOI, Aeicher, PWD,railways Pop,demographic, land use-TMC Employment-TMC,TMA,TSSIA Passengers-TMT,Railways Primary source: Traffic volume survey,O-D survey,House hold- survey, Road Network inventory,Speed and delay survey,Terminal survey,IPT survey - MSRDC
Global Positioning System(GPS) • for Geo-referencing • PAN+LISS III base data • 10 no of GCPs • Spheroid : World Geodetic System(WGS) • Datum :1984 • Projection: Universal Transverse Mercator(UTM)
Map Registration GCP values from GPS Geo reference the imageries Imageries ready for vectorisation & Analysis
