1.INTRODUCTION – Level of Service

• The intention of LOS is to relate the traffic service quality to a given flow rate of traffic. It is a term that designates a range of operating conditions on a particular type of facility.

1 INTRODUCTION -Limitations of IRC 106:1990

1. No revisions are made since 1990.2. The capacity values described are much low for

the present scenario.3. LOS is area specific and no provisions are

provided according to areas.4. It is proposed only for mid block sections and not

at intersections.5. It is based on HCM 1985-which is developed for

homogenous traffic.6. Only free flow speed is considered as the

parameter to define

3. Literature Review-Summary

• Literature review

PhD review Savitha B G

Literature Review• There is need to modify the IRC 106-1990.• The studies have to be carried out for junction in

urban roads to define the new LOS.• The heterogeneous traffic behavior to be studied.• Simulation models to derive the capacity and

service volume of the roads.• Modification of HCM2000 to suit to Indian

conditions

4. Data Collected• UnSignalized intersection• 2 Signalized intersection.

• LOS is F-peak hours• LOS is E-off peak hours

6. Scope of the study

1. To study the drawbacks of IRC 106:19902. To study the limitations of HCM 2000 according

to Indian heterogeneous traffic conditions.3. To suggest new values to amend for IRC 106-

1990

7. Methodology1. Study and characterization of the basic road

traffic flow characteristics such as speed, flow , density .

2. Development of capacity & LOS determination procedure for different categories of Indian Urban roads including quantification of the impact of various roadway, traffic and environmental factors on the capacity and level of service

3. Development of simulation model.4. Validation of simulation model.

8. Simulation• SUMO- open source traffic simulation software.

Traffic SimulationSimulation of Urban Mobility (SUMO)

Introduction• Computational simulation has the advantage of

allowing the assessment of system's behavior before it is developed or produced in real life.

• Traffic simulation is necessary because this kind of application domain is inherently complex, usually formed of diverse entities (vehicles, traffic controllers, pedestrians etc.) that present different interactions reflecting social behaviors (e.g. competition, collaboration).

SUMO - • SUMO allows modelling of intermodal traffic

systems including road vehicles, public transport and pedestrians.

• Microscopic simulation - vehicles, pedestrians and public transport are modeled explicitly

• Time schedules of traffic lights can be imported or generated automatically by SUMO
