Many Eastern European cities have experienced in their post-communist development the explosive effect of car usage on networks that have not been designed for car-mobility.The research analyses an accessibility measure-based on different network characteristics and embedding reliability - and illustrates how urban planners can use this measure in their transport related policies.A geographical formulastion for accessibility including network characteristics, and attributes of the service provided such as average traffic conditions (time, cost) and reliability is used.This represents a macro measure of accessibility that lacks the direct relationship between individual's choice and accessibility through bands of isochrones, it isconsidered possible to filter out the effect of reliability expected to influence the travel patterns.Few studies consider travel time uncertainty on the potential of reaching various destinations, and even fewer for emerging countries, where land use and transport planning practices have not been adapted to new mobility patterns. This research will include topological accessibility (position in the network) and distance accessibility for private and public transport separately, and then combine them to highlight their local interactions.Based on GIS and operational data-from various public transport agents and road authorities, in node accessibility the access/egress characteristics and the travel time variability were assessed.Different maps of accessibility to different transport networks and combinations of them are drawn.In Bucharest the road is shared with or dominatedby passenger cars and freight vehicles.Parking on roads is also a major problem, especially in residential areas where very few parking spaces wereplanned.The most immune to traffic congestion was found to be the underground network and the least immune are the bus and trolleybus. Finally, changes in accessibility resulting from different operation and development scenarios were examined.Two examples have been selected as representative:introducing a new light tram route and bus lanes for express routes.This isparticularly useful for transport planners and communities lobbying for infrastructure projects funding destined to alleviate the surface traffic conditions.
