The entry of
autonomous vehicles is expected to affect parking in cities. Prior research has
predicted a drop in demand for parking along side-curbs, due to the ability to shift
parking locations away from city centers to more remote areas, and due to
travel sharing that will require less parking time. This study examines whether
conversion of urban side-curb parking lanes into public transportation lanes will
reduce traffic congestion, using the Tel-Aviv Activity Schedule Model in the
central area of Tel Aviv metropolis.
The two-staged analysis first involved identification of side curbs parking lanes that are suitable for conversion. In total, 31% of the side-curb parking lanes could be converted to public transportation lanes, adding 445 km of public transportation lanes. The simulations were tested in two scenarios; The first scenario included changing-demand, and the second scenario included constant-demand. In order to estimate the effect of the conversion on traffic congestion, the results of the simulations were compared to the reduction in traffic projected for the red line project of the Tel-Aviv metropolis light rail, which will operate in the same area that was examined in this research.
The simulations showed that conversion of curb-parking lanes to public transportation lanes led to maximum time savings of 7-8% for public transportation passengers in the constant-demand scenario, and of 6-7% time savings in the changing-demand scenario. In both scenarios, there was a growth in the use of public transportation, manifested by an increase in the number of kilometers traveled by public transportation passengers. In constant-demand simulations, traveling additional kilometers was preferred over traveling in lines that were shorter in distance but not in time. This finding demonstrates the tradeoff between time and distance - passenger indifference to travel distance and their desire to arrive at their destination in minimum time. In changing-demand simulations, the increase in the number of kilometers was also an expression of the growth in the number of passengers using public transportation. In addition, we noted a significant need for traffic congestion reduction solutions in residential areas, attributed to the low level of service (V/C>0.75) in these areas and to their large proportion in the metropolitan area.
Comparison of the reduction in traffic congestion between the conversion of side-curb parking lanes into public transport lanes and the red line project of the Tel-Aviv light rail transit, showed that in the short term, the total time saved by passengers using public transportation was higher in the lane-conversion solution. However, both alternatives failed to significantly increase time savings and reduce traffic congestions.
