BETTER AIR QUALITY 2004 SPECIFIC TRANSPORT MEASURES TO REDUCE EMISSIONS IN HYDERABAD, INDIA Yash Sachdeva, RITES Ltd Viresh Goel, RITES Ltd D.S.Chari, RITES Ltd DECEMBER, 2004 AGRA, INDIA

TRANSPORTATION POLICIES FOR SUSTAINABLE DEVELOPMENT Typical policy alternatives to reduce emissions in developing countries have relied mainly on technology improvements While technology improvement is desirable, the impacts of transportation policies on emissions also need to be considered Maintaining mobility levels also important for sustainable development This IES component should help policy makers understand the broader impacts of transportation policy

DIAGRAM OF TRANSPORTATION ASSESSMENT PROCESS

TRAVEL DEMAND FORECASTING Takes raw inputs in the form of forecasts of – Population – Employment – Socio-demographic information – Spatial distribution of activities – Transportation networks and services offered Produces forecasts of – Volume of traffic for each important link in a transportation network (for all modes) – Operating speeds along those links Traffic volumes factored up to aggregate forecasts of PKT and VKT Speed and aggregate volumes used to calculate emissions, using a vehicle emissions package Feedback loop technique used to assess induced transport demand

PART- I : SCENARIOS FOR MORE EFFECTIVE PUBLIC TRANSIT SERVICE Business-As-Usual(BAU) Scenario Further decline in bus ridership Increase in use of personalized and IPT modes Increase in traffic congestion on roads Further decline in bus speeds which will lead to high travel time Higher vehicle km by 2-wh,cars and auto rick. Increase in emissions from motorized vehicles Goal of this component: quantify BAU and alternative public transport scenarios

ALTERNATIVE OPTIONS TO MAKE BUS TRANSPORT SYSTEM MORE EFFECTIVE Exclusive bus lanes/ways Provision of adequate and well designed bus stops Priority of buses at traffic signals Bus Route Rationalization

PART-II: TRAFFIC MANAGEMENT AND MEASURES TO IMPROVE TRAFFIC FLOW Corridors I. Sanathnagar to Nalgonda ‘X’ Road Corridor (12.6 km) II. Panjagutta to Secunderabad Corridor ( 8 km) Three scenarios developed for the identified corridors viz. – BAU Scenario – GEP Scenario(Reduction of Side friction,Provision of Foot path, Synchronization of Traffic signals along with junction improvements to reduce intersection delays) – Flyover Scenario(for corridor from Sanatnagar to Nalgonda ‘X’ Road)

PART-III: VEHICLE TECHNOLOGY/ TRAINING MEASURES RELATED OT TWO-STROKE VEHICLES 80% of 2 Wheelers are with 2-stroke engines 3 Wheelers are predominantly with 2-stroke engines Fuels blended with lesser quality fuel(adulteration) Inconsistent driving habits As a result, 2-stroke two or three wheelers in Hyderabad contribute quite disproportionately to air quality problems.

TWO - STROKE MAINTENANCE & OPERATIONS(M&O)TRAINING M&O Training programs can spread awareness and reduce emissions. Goal of component: What is the envelope of improvement that can be expected, and how cost effective would that be?

RECOMMENDATIONS Improved bus transit can attract traffic from 2&3 wheelers,cars and reduce emissions significantly.Therefore, more effective bus transit services should be provided. Traffic Management Measures such as removal of side friction,segregation of vehicular and pedestrian traffic and synchronisation of traffic signals should be implemented on all the major corridors wherever feasible. These measures are low cost and very effective in reducing vehicular emission levels. Although long flyovers attract higher traffic as compared to BAU scenario, they can still reduce emissions. However, construction of flyover should be planned carefully in view of the issue of sustainable development. Training programs and publicity for better maintenance of vehicle and proper driving habits of 2-stroke vehicle drivers should be carried out regularly.
