7 What makes SIDRA INTERSECTION different? STRONG RESEARCH BASE: Empirical and theoretical methods combined... Metering Signals Research for VIC ROADS 20 years at Australian Road Research Board 14 years at Akcelik & Associates 7 of 38

8 What makes SIDRA INTERSECTION different? Not just a roundabout software package! MODEL CONSISTENCY in evaluating alternative intersection treatments Micro-analytical method for evaluating alternative treatments for INTERSECTIONS AND NETWORKS in one package: Roundabouts Signals Sign Control Pedestrian Crossings 8 of 38

9 What makes SIDRA INTERSECTION different? MODEL CONSISTENCY for different intersection types (definition of delay, back of queue, stops, etc). Unique gap-acceptance method by signal analogy helps to model back of queue and stops for roundabouts and twoway sign control. Important for NETWORK Modeling 9 of 38

10 What makes SIDRA INTERSECTION different? LANE-BASED MODEL More realistic and reliable analysis compared with approach - based and lane group (link) - based methods from UK and USA: General: Unequal lane flows, De facto exclusive lanes, Short lanes (approach and exit), Slip / Bypass lanes (Giveway / Yield, Continuous, Signals) Roundabouts (Circulating lane use; Dominant and subdominant lanes) NETWORK Model (lane queues, lane blockage, signal platoon arrival and departure patterns) Individual approach, exit and circulating lanes have different characteristics Slip / Bypass Lane for BUSES ONLY Approach Short Lane Exit Short Lane 10 of 38

11 What makes SIDRA INTERSECTION different? VEHICLE PATH model for stop-start traffic Emissions - CO 2, CO, HC, NO x Fuel Consumption Operating COST Also used for Geometric Delay calculations Distance Speed Four Basic Path Elements Time Time 11 of 38

12 Acceleration Deceleration models Polynomial acceleration profile model Light Vehicles Heavy Vehicles 12 of 38

15 What makes SIDRA INTERSECTION different? Includes two Roundabout Capacity Models SIDRA Standard (calibrated for US driving conditions) HCM 2010 Common fundamental features: Geometry and Driver Behavior (Gap Acceptance) effects combined Lane-based method Empirical and theoretical methods combined Non-linear form 15 of 38

16 Dominant lane follow-up headway (s) Dominant lane critical gap (s) What makes SIDRA INTERSECTION different? SIDRA Standard Model Advantages Numerous extensions More extensive GEOMETRY parameters than HCM 2010 Follow-up Headway and Critical Gap values decrease with increased circulating flows More capacity Di = 30, ne = 1 Di = 50, ne = 2 Di = 80, ne = More capacity Di = 30, ne = 1 Di = 50, ne = 2 Di = 80, ne = Circulating flow (pcu/h) Circulating flow (pcu/h) 16 of 38

17 What makes SIDRA INTERSECTION different? Roundabout Geometry 17 of 38

18 What makes SIDRA INTERSECTION different? Now a powerful lane-based micro-analytical NETWORK MODEL all intersection types (signals, roundabouts, sign control) easy to configure using SIDRA Sites diverse Movement Classes Light Vehicles Heavy Vehicles Buses Bicycles Large Trucks Trams / Light Rail two User Classes Combined with the lane-based method, new Movement Classes allow modeling of Bus Priority Lanes, Bicycle Lanes, and so on 18 of 38

19 What makes SIDRA INTERSECTION different? Unique Method for Complex Network Design and Congestion Modeling Backward spread of congestion (reduced upstream capacity) Capacity constraint (reduced downstream arrival flows) The two basic elements of the model are highly interactive with opposing effects. SIDRA INTERSECTION 6 uses a network-wide iterative process to find a solution that balances these opposing effects. Backward spread of congestion and capacity constraint are common to all intersection types. 19 of 38

20 SIDRA INTERSECTION Version 6 SIDRA NETWORK model: Backward spread of congestion: capacity reduction at upstream lanes blocked by downstream lane queues. Capacity constraint: oversaturated upstream lanes reduce demand volumes for downstream movements Lane Movements: blockage of upstream lanes depends on lane choices of movements from approach lanes to exit lanes Upstream and downstream lane flows and mid-block lane changes on an approach to determine platooning. 20 of 38

33 SIDRA Model Success Stories Example 3 SIGNALISED INTERSECTIONS US North Carolina State University carried out a comprehensive study and evaluation of alternative software packages for signalised intersections (SIDRA, TRANSYT, HCS/HCM, Signal 94, HCM/Cinema, EVIPAS) for the North Carolina DOT. The report stated: SIDRA s powerful combination of high model usability, superior matching of field delays at the lane group level, versatile optimization features, and graphical user interface makes it the model of choice.. 33 of 38
